Reciprocal crosses were made among seven barley genotypes of diverse origin. Parents and 42 F1's were grown in a randomized block design with four replications in the greenhouse. Chlorophyll fluorescence activity of the penultimate leaf (below flag leaf) of the main stem at flowering were measured for each plant. Leaf blade area and its duration were also determined for the above-mentioned leaves. "Leaf blade area × leaf life duration" was also used as a trait. Results of diallel analysis showed that both general and specific combining abilities were significant for all the characters studied. General combining ability values and effects were usually more important than those of specific combining ability, showing the importance of additive genetic control for the traits. Reciprocal effects were significant only for chlorophyll fluorescence activity. Narrow sense heritability values for leaf area, leaf duration, and its chlorophyll fluorescence activity were 87.9, 66.8, and 77.4%, respectively. Key words: combining ability, reciprocal effect, heritability, fluorescence, leaf area.

Texto completoResumen
Anthurium andraeanum Hort. is an important tropical ornamental crop regarded as second only to orchids in its commercial importance. The genetic basis for productivity in anthurium was studied using parent–offspring regression analysis. Sixteen parental genotypes (4 years old) and 14 biparental progeny families (60 plants each, 4 years old) derived from the parents were used in the study. Yield expressed as number of cut flowers per plant per year (CFPY) was significant both between parental genotypes (P < 0.001) and between progeny families (P < 0.05). Mean CFPY of the parent genotypes was normally distributed and ranged from 4.8 in ‘Local Mina Red’ to 9.8 in ‘Kalapana’ with a mean of 7.5. CFPY in Year 1 was strongly correlated to that in Year 2 (Pearson’s r = 0.96; Spearman’s r = 0.93) and the broad sense heritability (H2) was high (87.6%) under controlled shadehouse conditions. CFPY in the progeny families varied from four to 14 with progeny means ranging from 5.7 in ‘Honduras/Local Mina Red’ to 7.2 in ‘Mirjam/Kalapana’. Progeny of seven and 10 crosses possessed mean CFPY greater than that of the more productive parent and the midparent values, respectively. The frequency distribution for productivity of the 840 progeny plants was skewed to the right with a modal class of six to seven. The correlation coefficient between progeny CFPY and midparent CFPY was large and significant (r = 0.90, P < 0.001). The regression of mean progeny CFPY on mean midparental CFPY was strong (y = 0.51x + 2.56; R2 = 0.81) with an estimated narrow sense heritability (h2) of 51.0%. A breeding strategy for improving per plant productivity based on the results is discussed.

The effects of GCA samples according to the results of dialysis analysis are given. Genetic control systems of traits of each variety are reflected, in particular the relative contribution of dominant and recessive alleles. According to the analysis of the effects of general combinatorial ability, samples with high indicators were selected for most of the studied features: the number of vegetatively elongated shoots - Poltava 52; foliage - Anto; dry matter yield - Poltava 52; protein content in dry matter - Poltava 52; the number of generative shoots - Anto and Poltava 52; panicle length - Anto and Radio-mutant k-7; seed productivity - Anto. A high level of the coefficients of heredity of the studied signs in a broad sense (H2 = 0,93 – 0,99) have been established. The coefficients of heredity in the narrow sense (h2) in terms of genetic variability due to additive effects of genes were different. The highest rate was in seed productivity (0,91), the number of vegetatively elongated shoots (0,78), dry matter yield (0,70); the lowest - in the length of the panicle (0,35) and the height of the plant - (0,43). The protein content was average (0,58). Key words: unbearded hundred-spike, diallel crosses, general combination ability, heredity.

This project examined rose (Rosa ×hybrida) performance by measuring flower size and flower numbers per inflorescence in spring, summer, and fall seasons (mean temperatures 21.7, 30.0, and 18.1 °C, respectively) in interrelated rose populations. Populations and progeny differed in flower size as expected. Heat stress in the summer season decreased flower diameter (18%), petal number (17% to 20%), and flower dry weight (32%). Analysis of variance (ANOVA) showed a significant population/progeny × heat stress interaction for flower diameter indicating that rose genotypes responded differentially to heat stress. Flower size traits had moderate low to moderate narrow-sense (0.38, 0.26–0.33, and 0.53 for flower diameter, petal number, and flower dry weight, respectively) and moderately high to high broad-sense (0.70, 0.85–0.91, and 0.88 for flower diameter, petal number, and flower dry weight, respectively) heritability. Genotype × environment (G × E) variance (population/progeny × heat stress) for flower diameter accounted for ≈35% of the total variance in the field experiment indicating that heat stress had moderate differential genotypic effects. However, the genetic variance was several fold greater than the G × E variance indicating selection for flower size would be effective in any season but for the selection of a stable flower size (heat tolerant) rose genotype, selection would be required in both the cool and warm seasons. Seasonal differences in flower productivity of new shoots did not appear related to heat stress but rather to the severity of pruning conducted in the different seasons. The number of flowers produced on the inflorescence had moderate narrow-sense (h2 = 0.43) and high broad-sense (H2 = 0.75) heritability with a moderate genotype × pruning effect that explained about 36% of the variance.

Abstract The concept of sustainability and the feasibility options have been discussed in specialized literature sources for about three decades only. Sustainable development has several definitions; it is defined both in narrow and wider sense. The definition of sustainability is regarded inevitable because the sustainability of agriculture can be interpreted only within this fixed conceptual framework. Our study primarily deals with issues of sustainability in farming practices being specific to countries and regions of the European Union. In frames of the current research we provide the analysis of the ability to produce value added within agricultural sector, the intensity of farming, the non-renewable external input use, farm structure as well as the European-level relations being directed towards the preservation of land productivity.

The survival, initial productivity, and the genetic parameters of Corymbia citriodora subsp. citriodora (CCC), Corymbia citriodora subsp. variegata (CCV), and Corymbia torelliana (CT) were used to develop a breeding strategy for the Corymbia species. Survival, height, and diameter at breast height (DBH) data were assessed 24 and 36 months after planting, and the mean annual volume increment was estimated in three trials. Longitudinal DBH data analysis was applied individually to each trial to identify the best and the poorest families at both ages. The mortality ranged from 5% in CT to 27% in CCC, and the mean annual increment varied from 17.8 to 20 m3·ha−1·year−1 at 36 months after planting. The 36-month narrow-sense heritability [Formula: see text] was high for CCV (0.69 ± 0.17), moderate for CCC (0.41 ± 0.11), and low for CT (0.21 ± 0.09). The genetic parameters indicated the need for different breeding strategies for each species. Selecting the best families while roguing the poor families allowed forward selection of CCC and CCV. It was possible to select good CT trees for hybrid breeding; however, improving the species population requires focusing on increasing the effective size and expanding the genetic variability in the CT population.

Texto completoResumen
Although an average plant height is more preferable in most of agronomic crops, less reduction of this trait in stress condition makes yield components and seed yield sustainable in rapeseed varieties. Combining ability, heterosis and heritability of plant height at application and non-application of nitrogen environments (Hp and Hs, respectively) and its related stress tolerance indices were detected in half F2 diallel crosses of six spring rapeseed varieties. Significant mean squares of general and specific combining abilities (GCA and SCA) were detected for Hp, Hs, mean productivity (MP), geometric mean productivity (GMP) and stress tolerance index (STI), indicating the importance of additive and non-additive genetic effects for them. A high narrow-sense heritability estimate was exhibited for STI, emphasizing the prime importance of additive genetic effects for this stress tolerance index. A significant correlation among Hp, Hs, MP, GMP and STI showed the efficiency of these stress indices for improving plant height in plant breeding programme. In comparison to SCA effects, most of the crosses had significant high parent heterosis for Hp, Hs and all the stress indices. RGS003 with a significant positive GCA effect of Hs was considered as a suitable parent for improving this trait and most of the combinations of this genotype had significant negative SCA effects.

Texto completoResumen
Height growth for interior spruce (Piceaglauca (Moench) Voss and P. engelmannii Parry) after 3, 6, and 10 growing seasons was assessed in a progeny test of 174 wind-pollinated families at three test sites in north central British Columbia. Test sites had a major influence on the juvenile growth of interior spruce, reflecting differences in potential site productivity as well as the importance of good site preparation and subsequent brush control for spruce seedlings. Mean heights within and across sites differed among families. The 3- and 6-year family performances correlated with family performances at age 10. Family–site interaction was significant at the 1% probability level, but accounted for no more than a quarter of the family variance at the three assessment years. Performance of the top and bottom 25% of families was consistent across the three sites. The narrow-sense heritability estimates after the third, sixth, and tenth growing seasons were 0.52, 0.36, and 0.29, respectively. The corresponding family heritability estimates were 0.82, 0.73, and 0.67, respectively.

Crop and Pasture Science 72, n.º 7 (2021): 565. http://dx.doi.org/10.1071/cp21018.
Texto completoResumen
Information on the nature and amount of genotype × environment (GE) interaction for economic traits and persistence is extremely rare in smooth bromegrass (Bromus inermis Leyss.), especially under drought stress. In this study, 25 half-sib (HS) families of smooth bromegrass were evaluated in the field during five consecutive years under normal and water deficit conditions. The effect of water deficit on dry forage yield was increased from the first year to the fifth, and manifested as a decline in persistence of HS families. Based on narrow-sense heritability estimates, additive gene action was found to be an effective factor in the control of yield components, whereas forage yield is controlled by both additive and non-additive gene actions. Considering the three parameters of stability of combining ability, mean performance and drought tolerance simultaneously, it was inferred that four parental genotypes were superior and stable with high values of general combining ability. This indicates that when developing synthetic varieties from these genotypes, both stability and plant productivity are transmitted to their progenies.

Texto completoResumen
A 3-year study on the incidence and severity of leaf rust caused by Melampsoraoccidentalis on hybrid poplars began in 1987 when inter- and intra-specific crosses were made with 20 Populustrichocarpa (T), 8 Populusmaximowiczii (M), and 3 Populustrichocarpa × Populusdeltoides (TD) parents. A total of 5100 seedlings from 67 families were initially surveyed for rust in 1988; however, this number declined to less than 3700 by 1990, and rust infection likely contributed to seedling mortality. There was significantly greater rust incidence and severity in T × T crosses than in T × M, M × TD, TD × M, or M × M crosses. For the 12 M × M crosses and the 6 three-way crosses (M × TD, TD × M), less than 1% of the seedlings had any rust in the 3 years. In the 20 T × M crosses, over 65% of the seedlings showed no rust and less than 1% showed heavy rust. For T × T seedlings from 29 crosses, less than 3% had no rust. Reciprocal crosses of P. trichocarpa from east or west of the Cascade Mountains in Washington showed that the female parent contributed more to rust susceptibility than the male parent. In regression analyses, P. trichocarpa midparent rust ratings were negatively correlated with family survival and positively correlated with the mean progeny rust rating. Narrow-sense family heritabilities were moderate to high for rust susceptibility (h2 = 0.43 in 1988, 0.53 in 1989, and 0.79 in 1990).

Growth and morphology of 308 black cottonwood (Populustrichocarpa Torr & Gray) clones were studied at one plantation site in northwestern Washington. The material was derived from both open-pollinated seed and branch cuttings from 10 natural populations in major river valleys west of the Cascade Range, between central Oregon (latitude 44°44′) and southern British Columbia (latitude 49°05′). Most of the clones (258) were derived from open-pollinated seedlings, with approximately six from each of two to five selected parents per population. Fifty of the clones were ramets from five field-selected ortets per population. Each clone was represented by two ramets in each of two blocks in a randomized complete block design. Three-year height and diameter growth displayed the largest amount of variation at the clonal level, followed by lesser amounts at the family and population levels. A significant block × clone interaction, combined with some responses contrasting with earlier studies on a different site, suggests that the interaction of genotype with environment is important for this species. Weak clinal trends were observed, despite a large degree of within-population variation. Narrow-sense heritability estimates and their standard errors were 0.10 ± 0.08 and 0.13 ± 0.09 for 3rd-year height and diameter, respectively. Significant trait correlations were obtained between volume and branch characteristics. The implications of these results and their relationship to other ongoing work in black cottonwood are discussed.

Texto completoResumen
AbstractAcoustic time of flight and drill resistance (surrogates for wood stiffness and density, respectively) were measured on 11,097 standing trees from 269 pollen-mix families of loblolly pine (Pinus taeda L.) in 6- to 9-year-old progeny tests at eight sites across the southeastern United States. Specific gravity was measured on two test sites. The phenotypic correlation between specific gravity and drill resistance was moderate (r = 0.68), whereas the genetic correlation was very strong (rg = 0.96). Narrow-sense heritabilities for acoustic time of flight and drill resistance were around 0.35 for individual trees and very strong (0.90) for family means. High genetic correlations (>0.80) between pairs of sites suggested a low genotype-by-environment interaction for both traits. Genetic correlations between wood quality traits and other economic traits (growth and stem straightness) were low except for a moderate correlation between acoustic time of flight and tree slenderness (rg = –0.64). The checklot ranked near the middle for both wood quality traits, implying no inadvertent selection occurred in this population that has been selected intensively for volume productivity. This study is the first to apply these tools in a large breeding program, and results suggest they are effective for selecting genotypes for wood quality.

In 2017, the Singaporean government unveiled the Farm Transformation Map, a highly technology-driven initiative that intends to change its current, near-total dependence on imported food. The plan focuses on the prospect of high-productivity farming—in particular, integrated vertical, indoor, and intensive urban farming—as a possible solution to geopolitical uncertainty, intense urbanisation, and environmental degradation. What to farm (or not) and how to farm has long mediated social, cultural, political, and environmental relations. Following the stories of a few small- to medium-scale urban farms, including rooftop gardens, community farms, and organic farms, in this future-oriented city polis, this article explores the rise of urban farming through the politics of localism and the notion of care. How has localism, in some contexts, been reduced to a narrow sense of geographic location? What is being cared for in and through farming in urban locales? How might this type of farming transform and shape bio-cultural, social-technological relations within humans, and between humans and non-humans? More importantly, this article explores how urban agriculture might forge a kind of thick localism rooted in situated care as it carries out social missions, experimenting with and subverting the dominant imaginary of industrial farming.

Agriculture is one of the important and complex sectors, it is not only a simple economic sector but also a biological - technical system. Because the basis for agricultural development is the use of bio-energy - plants and animals. Agricultural sector, if understood in a narrow sense, is only the cultivation, husbandry and service sectors. As for agriculture, in broad terms it also includes forestry and fishery. Agriculture provides food and food for social needs, agriculture is the basic material production industry, plays a major role in economic development in most of the country, especially in developing countries. At present, Vietnam’s agriculture has great potential and can be enriched from agriculture. However, wastage and loss in agriculture are still high in the stages of processing, harvesting and preserving. Mechanization is still low, lower than Thailand, so agricultural labor productivity is not high. Over the past years, Vietnam’s Agriculture has achieved important developments, contributing to the development of Vietnam’s economy. However, to achieve higher goals in the next 10 years, Vietnam’s agriculture needs to promote its strengths, such as: Well implementing land policies in agriculture; training high quality human resources; building a credible agriculture, which is clean, safe, quality agriculture and organic agriculture; protect natural environment, such as: land, climate, weather, hydrology, etc. In order to ensure sustainable agricultural development.

Texto completoResumen
Sugarcane is a major industrial crop cultivated in tropical and subtropical regions of the world. It is the primary source of sugar worldwide, accounting for more than 70% of world sugar consumption. Additionally, sugarcane is emerging as a source of sustainable bioenergy. However, the increase in productivity from sugarcane has been small compared to other major crops, and the rate of genetic gains from current breeding programs tends to be plateauing. In this review, some of the main contributors for the relatively slow rates of genetic gain are discussed, including (i) breeding cycle length and (ii) low narrow-sense heritability for major commercial traits, possibly reflecting strong non-additive genetic effects involved in quantitative trait expression. A general overview of genomic selection (GS), a modern breeding tool that has been very successfully applied in animal and plant breeding, is given. This review discusses key elements of GS and its potential to significantly increase the rate of genetic gain in sugarcane, mainly by (i) reducing the breeding cycle length, (ii) increasing the prediction accuracy for clonal performance, and (iii) increasing the accuracy of breeding values for parent selection. GS approaches that can accurately capture non-additive genetic effects and potentially improve the accuracy of genomic estimated breeding values are particularly promising for the adoption of GS in sugarcane breeding. Finally, different strategies for the efficient incorporation of GS in a practical sugarcane breeding context are presented. These proposed strategies hold the potential to substantially increase the rate of genetic gain in future sugarcane breeding.

Texto completoResumen
In this article we developed scientific and applied foundations of commercialization of the nature-resource potential of anthropogenic objects, on theexample of exhausted mines. It is determined that the category of “anthropogenic object” can be considered in a narrow-applied sense, as specific anthropogenic objects to ensure the target needs, and in a broad theoretical sense, meaning everything that is created and changed by human influence, that is the objects of both artificial and natural origin. It was determined that problems of commercialization of the natural-resource potential of anthropogenic objects are most often considered by researchers for specific objects, without having complex methodological coverage from the point of view of combining environmental, technical, economic and managerial components. When studying the substantiation of the scientific base, the authors confirmed the feasibility of the commercialization of natural-resource potential of anthropogenic objects on the example of a number of theoretical scientific studies in reclamation, reconstruction, recreation, remediation, restoration of biological productivity and economic value of land disturbed by economic activity. The considered examples of exhausted mines in the 21st century in the USA, Canada, Germany, Romania, and Poland indicate a wide range of opportunities for their commercialization. The study of the potential for commercialization of exhausted mines in the post-Soviet countries testified to the underused reserves for the commercialization of their nature-resource potential and their high potential for further development. The authors proposed the identification of anthropogenic objects on the basic livelihood spheres of society. There were identified the main system (natural, biological, technical, economic, social,managerial) and structural (subjects, trends, threats, risks, problems, challenges) factors of diagnosing the state of an anthropogenic object. A set of measures has been developed for commercialization of an anthropogenic object in functional and production activities, product policy, financial and investment spheres, pricing and sales policies, promotion, management and determination of property rights. Recommendations were provided on optimizing the management decision-making process based on a set of positivistic development principles, methods, and management functions. The study allows international organizations, state and local authorities, territorial communities, owners and potential investors to see new opportunities and make mutually beneficial decisions on the rational use of the nature-resource potential of anthropogenic objects.

Mechanization is one form of technology adoption to improve yields in rice farming. The aims of the research to determine the use of agricultural mechanization and its impact on rice farming in Sananwetan Sub-District, Blitar City expected to improve the standard of living and welfare of its group members. The number of samples taken was 50 rice farmers in Sananwetan Sub-District, Blitar City, chosen by using proportional random sampling. Data analysis using the Mann-Whitney Test and the Multiple Linear Regression Cobb Douglas Model. From the results of interviews in this study show that the use of the mechanization of rice farming in Sananwetan Sub-District, Blitar City is still not optimal. This was due to farmers' perceptions of the unsatisfactory results of agricultural machinery performance, a sense of humanity to 'farm laborers', narrow land area and insufficient availability of farm machinery. While from the results of Mann Whitney's test show that pesticide use and labor requirements were smaller and differed significantly in the use of full mechanization rather than partial mechanization. Other than that, the variable cost of the harvest is lower in the use of full mechanization and is significantly different compared to using the mechanism partially. Rice productivity in full mechanization was 782.15 kg / 1000m2 while partial mechanization was 682.87 kg / 1000m2. For farmers' income in full mechanization is IDR. 1,153,407, - per 1000 m2, in the partial mechanization of IDR. 1,590,574, - per 1000m2. From Cobb Douglas model multiple linear regression analysis found that land area (m2), seed costs and the use of mechanization had a significant effect on the income of rice farming in Sananwetan District, Blitar City.

The cultivation of tomato in lowland experience many obstacles, such as low produvtivity. One effort to increase tomato productivity in lowland is through selection of tomato genotype for high yield and yield component in lowland. This study aims to determine the variability based on genetic information, heritability and correlation of characters as well as the yield components of tomato genotypes relationship patterns in the lowlands. A Randomized Complete Block Design was used to characterization base on best genotype of yield component character, genetic variability, broad sense heribility and correlation to yield. Genotype of tomato tested had diverse characteristics. Best genotypes based on the yield character is IPB T1, based on the number of fruit per plant is IPBT30, based on the fruit length and day to flowering is IPB T74, based on the fruit diameter is IPB T73 and fruit thickness is IPBT60. Wide genetic diversity has a high heritability. Number of fruit per plant, fruit length, fruit diameter, and fruit thickness has a wide genetic diversity and high heritability. Yield characters has a narrow genetic diversity and heritability is low. Characters that have a direct impact on the yield are the fruit diameter. Based on the cluster analysis, tomato genotypes are grouped into five groups. Group I consists of seven genotypes (IPBT1, IPBT58, IPBT60, IPBT64, IPBT78, IPBT80 and IPBT82), group II consists of one genotype (IPBT74), group III consists of three genotypes (IPB T13, IPB T73 and IPB T86), group IV consists of five genotypes (IPBT3, IPBT33, IPBT43, IPBT53, and IPBT3) which is characterized by fruit thickness, fruit length and days to flowering, and group V consists of one genotype (IPBT30).

The total samples which taken were 50 rice farmers of Sidomulyo Gapoktan in Sananwetan District of Blitar City. The sampling taken using purposive random sampling technique, which is deliberately chosed based on criteria which determined by the researcher. The Data analysis was carried out descriptively, using the Mann-Whitney Test and the Multiple Linear Regression Cobb Douglas model. Based on the results of the study, it was found that the mechanization of rice farming in Sidomulyo Gapoktan, Sananwetan District, Blitar City has not still optimal. This is caused by the farmers' perceptions of the results of unsatisfactory performance of agricultural machinery, a sense of humanity towards' farm labors, narrow area of farming and insufficient availability of agricultural machinery. The result of reseach which was used Mann-Whitney Test analysis, found that pesticide using and labor requirements were smaller and differed significantly in the use of full mechanization rather than partial mechanization. Harvest variable costs were lower in the use of full mechanization and were significantly different than using partial mechanisms. The Productivity of rice in full mechanization is 782,15 kg / 1000m2 while in partial mechanization was 682.87 kg / 1000m2. For farmers' income in full mechanization is Rp. 1,153,407, - per 1000 m2, in partial mechanization of Rp. 1,590,574, - per 1000m2. Multiple Linear Regression Analysis of the Cobb Douglas model shows that the land area (m2), seed costs and the use of mechanization have a significant influence on the income of rice farming in Sananwetan District, Blitar City.

Purpose The purpose of this paper is to argue that rather than contest the artificial schism produced by social scientists between “qualitative” and “quantitative” research, we should to accept this binary, however, contingently, and use it productively. This would be an act of “strategic essentialism” that would allow us to be productive in the research and inquiry. Design/methodology/approach The paper uses postcolonial theory to make a case for contingent representation, i.e. using artificial categories to carve out a space for heterodox theoretical approaches. Findings Researchers devoted to qualitative research must resist thinking, speaking and evaluating that research using quantitative thinking. Also, while ethical considerations are paramount in qualitative research, we need to debunk the narrow understanding of ethics as “following rules.” Also, qualitative researchers need to be aware of the institutional pulls that the research will be subject to, and also be ready to resist them. Originality/value This paper discusses how good research resists the siren call of institutionalization. It challenges the “common sense” assumptions of the field and brings them into the realm of the questionable. It seeks to theorize the untheorizable, and anthropologize the dominant.

Revista de la Facultad de Ciencias Agrarias UNCuyo 53, n.º 1 (7 de julio de 2021): 196–206. http://dx.doi.org/10.48162/rev.39.019.
Texto completoResumen
Protected Designation of Origin (PDO) is one of the EU tools for rural development. Most of the literature on this subject is focused on premium prices and consumers’ willingness to pay for local products, since PDO and other labels aim to provide premium incomes for farmers. Our assumption is that PDO drives unexpected changes of farming styles not only related to processing or market strategies but also related to local resources using and to stablishing of different approach to agriculture and food production. We analyzed the PDO Queso Palmero (La Palma cheese) as a case of a dual label system (brand–certification common label) because it gives us the opportunity to compare farmers involved in a PDO scheme with farmers who works outside such systems. We conclude that private brands are more important than common label certification in price formation, but both are complementary, since PDO reinforces farmers’ efforts to improve quality. Beyond premium price, PDO also drives a radical change in farm structures, since it reconnects products to local resources (grazing vs intensification) and redesigns relationships with markets (shortening and diversifying chains and widening product offer). This change is characterized by implementation of new farming strategies in the context of PDO structure that coexist with classical farming strategies closer to intensification, not only in terms of productivity but also in terms of decoupling from local resources and productive and market specialization. Therefore, PDO is a powerful tool for rural development in a wide sense (resilience, empowerment, local capacity and network formation among others) far beyond its narrow remit of promoting economic growth (local or regional). Therefore, the coupling with local resources and the strength of local network and relationships as source of resilience, knowledge and capabilities improvement, have to be included in performance assessment of GIs in order to broaden the appraisal of role in regional development.
Highlights
PDO as institution is a powerful tool of farm transformation not only a protection structure of collective heritage or asset.
Private brand effect on price is larger than common label effect (PDO label).
PDO as institution leads radical changes of goat production systems from more production – oriented toward more market – oriented styles.
Market chains and product diversification, focusing on quality, concern about consumers and coupling with local resources are distinctive features of farms involved in PDO.

Let $q\geq 3$ be a prime power. Maximal designed distances of primitive Hermitian dual containing $q^{2}$-ary BCH codes (narrow-sense or non-narrow-sense) are determined by a careful analysis of properties of cyclotomic cosets. Non-narrow-sense BCH codes which achieve these maximal designed distances are presented, and a sequence of nested non-narrow-sense BCH codes that contain these BCH codes with maximal designed distances are constructed and their parameters are computed. Consequently, new nonbinary quantum BCH codes are derived from these non-narrow-sense BCH codes. The nonbinary quantum BCH codes presented here have better parameters than those quantum BCH codes available in the literature.

Texto completoResumen
The paper discusses the results of a pilot study into derivational patterns and semantics of some neologisms referring to persons given in the Database of Lithuanian Neologisms (further also DLN). The research focused on nouns ending in -tojas, -a, -ėjas, -a, -ikas, -ė, ‑ininkas, ‑ė, ‑ėlis, -ė, -ūnas, -ė and -uolis, -ė. Most of these words are suffixal derivatives usually attributed to the categories of nomina agentis, nomina attributiva and nomina professonalia. The analysed suffixes are very different in their productivity. The suffixes -ininkas, -ė, -tojas, -a, -uolis, -ė are very productive, whereas the suffix -ėjas, ‑a, in Lithuanian grammars treated as one of the most typical and productive agentive suffixes, in the DLN have only been attested in a couple of words. The paper also discusses when a new phenomenon should be treated as a neologism and when it is merely a new sense of the existing word, included in some key publications based on the DLN. The investigation draws a conclusion that when analysing current situation and tendencies of word-building the formal principle of classifying neologisms is not operational. According to it, a compositional neologism coinciding with the already existing word is treated as a word with a new sense rather than a neologism. However, in cases when a new lexeme of an already existing word emerges as a result of a new derivational opposition, by building a word from a new or already existing lexeme of the base word, the new lexeme should be treated as a neologism rather than a new sense of the existing word. New senses (semantic neologisms) emerge in cases of semantic development of the word as a result of meaning transfer, lexicalisation and other processes. Another aspect of the present investigation focuses on the relationship between lexical senses and senses of individual derivation. An attempt was made to identify if lexical and derivational senses were the same or whether the former was narrower or broader than the latter. If they were not the same, causes of their divergence were identified. The latter issue might be relevant when analysing further processes of neologism lexicalisation. The paper also attempts to clarify the derivational patterns (origin) of some concrete neologisms and their semantic structure. Such interpretations are appreciated and very welcome by lexicographers, who are responsible for appropriately presenting neologisms in lexicographic publications. Alongside derivatives, analogous, mixed, contaminative formations as well as translations have been discussed. These derivative and formal aspects of neologisms might turn out to be very important in further investigation of larger and more varied groups of affixal derivatives and identifying general features of contemporary word-building. In pursuing the main goal of the investigation, an attempt was also made to discuss in more detail the DLN as a source of new Lithuanian lexis. It has been noticed that the DLN lacks a number of neologisms which are base words for the ones given in the database. They have all been attested on the internet. Such base words in the DLN would help define their derivatives without repeating the information which is inevitably given in the definition of the base word. Seeking precision, some definitions of the neologisms should be revised; for example, definition patterns of nouns should not be used to define adjectives. In some cases, a neologism given in the DLN as a single lexeme should be presented as two different lexemes, for example, the word pilstukininkas, –ė ‘someone who sells or drinks low quality home-brewed alcohol’ should be given as two lexemes representing two derivational categories: nomina professonalia and nomina attributiva. One of the goals of the investigation was concerned with exploring further prospects of researching the derivation of neologisms, posing the key questions and verifying their relevance. Presumably, the results of the investigation could be used in researching the tendencies of deriving neologisms in contemporary Lithuanian and comparing them with the tendencies described in the grammars of Lithuanian of the 2nd half of the 20th century. It would be interesting to ascertain how derivational patterns of neologisms are changing, when the lexicon is inevitably changing due to an enormous flow of information, more intensive communication in smaller communities and in the world, due to new emerging mass media and under the influence of other languages, especially English, which is structurally much more distant than Russian, a language having influenced Lithuanian several decades ago.

Texto completoResumen
SynopsisThe herbaceous vegetation of sand dunes is quite strongly influenced by a number of different grazing animals, principally vertebrates. Between 1985 and 1987 forty-eight dune sites were visited and studied, information being recorded on the vegetation and grazing status of 777 quadrats.The results of the survey confirm that the dominant grazing animal in British sand dunes is the rabbit. Over 70% of the quadrats are regarded as being rabbit-grazed directly and over 98% of the dune sites sampled appeared to be affected by rabbit grazing to some extent. Just over a third of the sites were grazed by cattle and a similar proportion by sheep; generally it was either cattle or sheep although five sites were grazed by both. There was only one site significantly grazed by ponies although a number of other sites were grazed occasionally by passing ponies.The intensity of grazing was very variable. Out of the forty-eight sites, three were regarded as being ungrazed and a further ten only lightly grazed, while nine sites were considered to be heavily grazed. However the remaining twenty-six sites were recognised as being intermediate only to the extent of not being obviously overgrazed or undergrazed. It was further recognised that the present state of the vegetation tended to reflect the grazing management in the recent past rather than current practice. A change in the grazing management often took many years to effect a permanent change in the vegetation.The grazing requirements to promote species diversity are very different for the different habitat types. In the yellow dunes the plant community is open with bare ground for colonisation and plant competition is not intense. There is thus little need for the control of plant growth by grazing.Dune grassland, in the narrow sense, needs to be grazed to maintain plant species diversity. The purpose of grazing is to remove prolific growth from the most vigorously growing plants to reduce competition. Lower grazing intensities are needed for all the year round grazing than when grazing is first applied to an area or is a permanent measure for limited periods of the year only.Dune slacks are generally best grazed by cattle and, with the higher soil moisture, grazing intensities can be higher than those applied to dune grassland. Excessive grazing is likely to cause serious damage to both the soil and the vegetation, especially in the wetter areas.Dune heath vegetation has a low productivity and its own special management problems. It needs to be grazed (or cut or burnt) to maintain the internal mosaic by the successful regeneration of the main species, but too much grazing will lead to conversion to a species-poor acid grassland.

By a careful analysis on cyclotomic cosets, the maximal designed distance δnew of narrow-sense imprimitive Euclidean dual containing q-ary BCH code of length [Formula: see text] is determined, where q is a prime power and l is odd. Our maximal designed distance δnew of dual containing narrow-sense BCH codes of length n improves upon the lower bound δmax for maximal designed distances of dual containing narrow-sense BCH codes given by Aly et al. [IEEE Trans. Inf. Theory53 (2007) 1183]. A series of non-narrow-sense dual containing BCH codes of length n, including the ones whose designed distances can achieve or exceed δnew, are given, and their dimensions are computed. Then new quantum BCH codes are constructed from these non-narrow-sense imprimitive BCH codes via Steane construction, and these new quantum codes are better than previous results in the literature.

Texto completoResumen
The fire-tolerant eucalypt forests of south eastern Australia are assumed to fully recover from even the most intense fires; however, surprisingly, very few studies have quantitatively assessed that recovery. The accurate assessment of horizontal and vertical attributes of tree crowns after fire is essential to understand the fire’s legacy effects on tree growth and on forest structure. In this study, we quantitatively assessed individual tree crowns 8.5 years after a 2009 wildfire that burnt extensive areas of eucalypt forest in temperate Australia. We used airborne LiDAR data validated with field measurements to estimate multiple metrics that quantified the cover, density, and vertical distribution of individual-tree crowns in 51 plots of 0.05 ha in fire-tolerant eucalypt forest across four wildfire severity types (unburnt, low, moderate, high). Significant differences in the field-assessed mean height of fire scarring as a proportion of tree height and in the proportions of trees with epicormic (stem) resprouts were consistent with the gradation in fire severity. Linear mixed-effects models indicated persistent effects of both moderate and high-severity wildfire on tree crown architecture. Trees at high-severity sites had significantly less crown projection area and live crown width as a proportion of total crown width than those at unburnt and low-severity sites. Significant differences in LiDAR -based metrics (crown cover, evenness, leaf area density profiles) indicated that tree crowns at moderate and high-severity sites were comparatively narrow and more evenly distributed down the tree stem. These conical-shaped crowns contrasted sharply with the rounded crowns of trees at unburnt and low-severity sites and likely influenced both tree productivity and the accuracy of biomass allometric equations for nearly a decade after the fire. Our data provide a clear example of the utility of airborne LiDAR data for quantifying the impacts of disturbances at the scale of individual trees. Quantified effects of contrasting fire severities on the structure of resprouter tree crowns provide a strong basis for interpreting post-fire patterns in forest canopies and vegetation profiles in Light Detection and Ranging (LiDAR) and other remotely-sensed data at larger scales.

Improving melon root systems by traditional breeding is one component of the program to develop multiple-stress-resistant melons at the Texas Agricultural Experiment Station, Weslaco. Ten diverse melon lines representing four horticultural groups were intercrossed utilizing a Design II mating scheme. The male parents were: `PI 403994,' `Perlita,' `Doublon,' `Caravelle', and `PI 525106.' The female parents were: `Créme de Menthe,' `Magnum 45,' `BSK,' `PI 124111 × TDI', and `Deltex.' F1 progeny were grown in pasteurized sand in the greenhouse using a randomized complete-block design with four reps. After 4 weeks, root systems from all plants were carefully washed to remove the sand. Each root system was then placed onto a glass, plated, and scanned into the computer software Rhizo Pro 3.8 (Regent Instruments, Quebec). This software calculated root lengths of various diameter classes, root area, and root tip number. All data was input into Agrobase software for calculation of genetic variances based on Design II analysis. Significant differences of contributions by male parents to progeny variation were few. Only length of roots with 1.0- to 1.5-mm-diameter and vine length were significantly different. Differences in contributions by female parents to all traits except root tip number were highly significant. No significant interaction effects were observed for any trait. Narrow-sense heritability estimates were moderate to high for all traits. The range was from 0.56 for root tip number by males to 0.81 for both length of 0.5- to 1.0-mm-diameter roots and vine length for females. Estimates for total root length (0.76) and root surface area (0.77) were high. The lack of male by female interaction suggests very low dominance genetic variation and contributed to high heritability estimates, which represent predominantly additive gene action. Additive genetic variation allows more-efficient progress by selection, making the potential for root system improvement favorable.

In this paper we test the narrow Porter hypothesis on a sample of European economies in the period 1995–2008. We focus on the channels through which tighter environmental regulation affect productivity and innovation. Our findings suggest that the “narrow” Porter Hypothesis cannot be rejected and that the choice of policy instruments is not neutral. In particular, market based environmental stringency measures seem to be the most suitable to stimulate innovations and productivity growth. Consistently with the strategic reorientation of environmental policies in the European Union since the end of the eighties, our results indicate that the EU might privilege the market based instruments in order to meet more effectively the 2030 targets, especially through the channels of innovation and productivity enhancement.

Texto completoResumen
The measurement of scholarly productivity is embroiled in a controversy concerning the differential crediting of coauthors. Some researchers assign equivalent shares to each coauthor; others employ weighting systems based on authorship order. Horan and his colleagues use simple publication totals, arguing that the psychometric properties of labor-intensive alternatives are unknown, and relevant ethical guidelines for including coauthors are neither widely understood nor consistently followed. The PsycLIT and SSCI data bases provided exhaustive publication and citation frequencies for 323 counseling psychology faculty. All PsycLIT scoring permutations yielded essentially identical information; inter-correlations ranged from .96 to unity. Moreover, all PsycLIT methods correlated highly with SSCI within a very narrow band. Since attention to the number and/or ordinal position of coauthors yields no useful information, productivity should be defined parsimoniously in terms of simple publication counts. Implications for research, promotion/tenure, and the mentoring of graduate students are discussed.

IntroductionPhenotype homogeneity and heritability are important conditions for identifying the genetic basis of bipolar I disorder (BPI) in association studies. Our objective was to study the heritability of mood-incongruent psychosis (MIP) in BPI in a sample of 504 families ascertained through BPI probands (294 females; 210 males) recruited from consecutive hospital admissions.MethodThere were 402 families with a psychotic proband and 275 families with a proband with MIP. All probands were directly interviewed as well as 79.55% first-degree and 22.59% second-degree relatives. The narrow and the broad sense heritability (h2) of MIP and the effect of sex and age were estimated using S.A.G.E.v.6.01-software (2009).ResultsThere was no sex difference for the psychosis prevalence in probands but MIP was two times more frequent in females than in males. In families with MIP probands the narrow-sense h2 for MIP was 0.14 (SE = 0.02, P = 0.002) and the broad-sense h2 was 0.20 (SE = 0.014, P = 0.0000). Significant but lower heritabilities were found in families with a psychotic proband (narrow-sense h2 = 0.12; broad-sense h2 = 0.13). In the total sample the narrow-sense h2 was 0.06 (P < 0.005) and the broad-sense h2 was 0.10 (P < 0.00001). The female sex was more prone to incongruency (χ2 = 33.32, P = 0.0000).ConclusionThe heritability of MIP was significant but not high in families ascertained through BPI probands regardless of familial psychopathology. These finding is in line with GWAS-studies showing that the polygenic score fails to differentiate psychotic BPI from non-psychotic BPI. Is therefore incongruent psychosis a useful dimension for association studies?

The latency to heading was examined in 115 lines under controlled environmental conditions, as well as in the field, and the degrees of narrow-sense earliness and vernalization requirement were evaluated for quantitative trait locus (QTL) analysis. Single-marker analysis using 107 RFLP markers segregating in RILWA-1 detected 20 linking markers for heading factors. In all marker loci, the alleles for early heading were conferred by T. monococcum. In interval analysis of chromosome 5Am, two vernalization genes, Vrn-Am1 and Vrn-Am2, were precisely mapped to the Xcdo504Xpsr426 interval on the central region of the long arm and to the Xwg114Xwec87 interval on its distal region, respectively. Interval analysis also showed that two genes for narrow-sense earliness, designated Nse-3Am and Nse-5Am, were located on chromosome 3Am and 5Am, respectively. It was noticed that heading time in the field was determined mainly by Nse-3Am, suggesting that narrow-sense earliness is critical for heading in the field in einkorn wheat.Key words: QTL analysis, einkorn wheat, heading time, vernalization requirement, narrow-sense earliness.

In the science of civil law, two approaches to the understanding and interpretation of accessory have been formed. The first approach can be defined as the understanding of accessory in the "narrow" sense, the second - in the "broad" sense. Russian civil law contains signs of accessory in the "narrow" sense. For this reason, the problem of the concept of "accessory" is seen, which is subject to the identification of an accessory legal relationship with a security obligation, which in turn impoverishes the idea of the role of accessory in the system of legal relationships. With the development of circulation and the complication of law, examples of accessory legal relations of a different kind appeared that were not related to security obligations, i.e. "Broad" understanding of accessory, which has an auxiliary, secondary nature of the obligation, which can not always have a security focus. Russian arbitration courts have developed a number of rules to make up for the shortcomings of the institution of accessory in Russian civil law, and the possibility of using accessory in the "broad" sense. It is concluded that de jure the concept of accessory in Russian civil law is reflected in the "narrow" sense, and de facto, accessory is applied in the "broad" sense.

Based on a polygenic system of a diploid species, without epistasis, and a population in Hardy-Weinberg equilibrium, without inbreeding and under linkage equilibrium, it can be shown that: (1) the narrow sense heritability at half-sib family level is equal to the square of the correlation coefficient between family mean and the additive genetic value of its common parent; (2) the narrow sense heritability at full-sib family level is equal to the square of the correlation coefficient between family mean and the mean of the additive genetic values of its parents; (3) the narrow sense heritability at Sn family level is exactly equal to the square of the correlation coefficient between family mean and the additive genetic value of its parent only in absence of dominance or when allele frequencies are equal; and (4) the broad sense heritability at full-sib or Sn family level can be used to analyze selection efficiency, since the progeny genotypic mean is, in general, a good indicator of parents, or Sn-1 plant superiority with respect to the frequency of favorable genes.
