Abstract:

The response of 25 registered winter wheat varieties to autumnal infection with Wheat dwarf virus (WDV) was studied in small plot trials in two years. The materials were infected by vectors, leafhopper Psammotettix alienus Dahlbom, 1851 from three-leaf stage to tillering. The symptoms expression was monitored in spring and plant height, weight of above ground biomass and grain yield were observed in summer. All tested varieties were evaluated as susceptible and divided into three groups: varieties Banquet and Svitava with 87.3–93.1% grain yield reduction as moderately susceptible, varieties Clever, Drifter, Niagara and Rialto with 95.6–97.68% grain yield reduction as susceptible and varieties Apache, Batis, Bill, Complet, Contra, Corsaire, Ludwig, Mladka, Nela, Record, Rheia, Semper, Sepstra, Solara, Sulamit, Tower, Trend, Vlasta and Winsdor with 99.7–100% grain yield reduction as very susceptible. Statistically significant differences were observed between moderately susceptible and susceptible varieties as well as very susceptible ones in absorbency values by means of DAS-ELISA.

Abstract:

Particular agronomic traits of six landraces of Triticum diccocum Schrank (Schuebl) were studied during three years in Prague and Česk&eacute; Budějovice localities, Czech Republic. The analysis of tolerance to drought by using the method of <sup>13</sup>C discrimination (CID) was also focused on in the research. All the tested varieties were resistant to usual wheat diseases. An inclination of particular varieties to lodging and a low harvest index rate (0.33) were negative factors having a significant effect on the yield rate. Meanwhile, all the varieties contained a high percentage of proteins in grain (17.92%) which was an important advantage in low input conditions. The landraces of emmer wheat also proved to be more tolerant to drought (CID = 25.82&permil;) than check varieties of bread wheat (CID = 26.70&permil;). Results of the research showed that some of the emmer landraces may be successfully grown and used directly in low-input farming systems or in breeding programs focused on the breeding of suitable varieties for low-input farming. &nbsp;

Abstract:

The dough characteristics of fifty popular Indian hexaploid wheat varieties were assessed by testing various rheological properties using a Brabender Farinograph and an Extensograph. These studies were aimed at evaluating the flour quality and functionality of the wheat dough. Based on the rheological dough properties of 50 Indian hexaploid wheat varieties it was recommended that 13 wheats could be useful for blending purposes, 31 varieties could be used for both bread and chapatti making, and the remaining 6 wheats were found suitable for biscuit making. The outcome of the experiments will be useful for plant breeders, millers and bakers.

Randhawa, H., Puchalski, B. J., Frick, M., Goyal, A., Despins, T., Graf, R. J., Laroche, A. and Gaudet, D. A. 2012. Stripe rust resistance among western Canadian spring wheat and triticale varieties. Can. J. Plant Sci. 92: 713–722. Stripe rust (Puccinia striiformis Westend.) is an important pathogen of wheat in western Canada and worldwide. One hundred and four spring wheat and triticale varieties and cultivars were evaluated for resistance to stripe rust in nurseries at Lethbridge and Creston, BC, during 2009 and 2010. In the Canada Prairie Spring Red (CPSR) wheat class, newer varieties were more resistant compared with many of the older varieties. Among the white Canada Prairie Spring White (CPSW) wheats, Vista was moderately resistant, whereas Snowhite475 and Snowhite476 were susceptible. Little useful resistance was observed within the Canada Western Hard White Spring (CWHWS) class. Sixty percent of the Canada Western Red Spring (CWRS) wheats, including the currently popular varieties Lillian, Harvest and Kane, were resistant. Susceptible CWRS varieties that are extensively seeded in western Canada include AC Barrie, Superb and McKenzie, but also include the recently registered CDC Kernen and Vesper. The varieties were tested for the presence of the stripe rust genes Yr10, Yr17, Yr18 and Yr36 using molecular markers. Much of the stripe rust resistance, particularly in the CWRS, Canada Western Extra Strong (CWES), and CPSR wheat classes was attributed to the presence of adult plant resistance gene Yr18. Yr17 and Yr36 were also detected among CWRS and CWES varieties. However, the absence of markers for known genes in several resistant varieties indicated that uncharacterized genes for stripe rust occur among hexaploid wheats. Durum wheat and triticale varieties were universally resistant with the absence of tested markers. Therefore, there appear to be numerous sources of stripe rust resistance, both characterized and uncharacterized, among western Canadian spring wheat and triticale varieties.

Abstract:

Variation in the electrophoretic banding patterns of high molecular weight (HMW) glutenin subunits of 274 hexaploid wheat (Triticum aestivum) varieties from China was examined by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Twenty-seven different major glutenin HMW subunits were identified. Each variety contained 3–5 subunits and 29 different glutenin subunit patterns were segregated. Seventeen alleles were identified based on comparison of subunit mobilities with those previously found for hexaploid wheat. Chinese hexaploid wheats exhibited particular allelic variation in glutenin HMW subunit composition and this variation differed from that found in wheats from Japanese and other countries. Average Glu-1 quality scores of 274 Chinese wheat varieties in the present study have been shown to be higher than that of Japanese wheats. Considerable genetic variation in the HMW glutenin subunit compositions of the Chinese wheats was observed in the present study and previously. Alleles from Chinese hexaploid wheat varieties have not been extensively introduced into Japan and other countries. The present data may indicate possible applications of Chinese germplasm in wheat breeding programs. To improve the wheat quality, genetic variation should be attempted through the introduction of genes of Chinese varieties into varieties in Japan and other countries.

Abstract:

Kailali is the second highest district regarding wheat production and area coverage. A study was carried out in the Kailali district for preference of farmers on different wheat varieties that were being cultivated in the district. The objective of the study was to assess farmers’ preference and perception on the different improved wheat varieties in the area. Five commonly grown wheat varieties and seventeen important wheat varietal traits were selected through focus group discussion, key informant interview and preliminary survey. Sixty households were selected for face-to-face personal interview, twelve for each selected variety, at random from Ghodaghodi Municipality, Gauriganga Municipality and Kailari Rural Municipality of Kailali. The weightage of the seventeen selected traits were determined using an online survey conducted among individuals from different designation with the agricultural background who were well known about wheat cultivation practices in Kailali district. Yield, flour quality and tillering were found to be the trait of higher weightage and stem thickness was the trait of lowest weightage. The preferences of the farmers were measured using wheat preference index (WPI). The varieties Vijay, NL-971, HD-2967, Gautam and Aditya were ranked as I, II, III, IV and V respectively. The incorporation of farmers' preferred traits in future wheat varieties would increase the likelihood of adoption of the varieties. Similarly, proper participatory field trial of new improved wheat varieties would also help in the selection of the suitable varieties in the area concerning the farmers’ criteria of selection. Int.

Abstract:

A field experiment was carried out during winter season of 2020-2021 at one of the fields of Al-Hamdhiya research station - College of Agriculture - Anbar University - Ramadi district in order to know the response of some growth traits, grain yield and its quality of several varieties of spring wheat to spraying of kinetin. Randomized complete block design (RCBD) according to split plots arrangement at three replications was used. The main plots were occupied by four concentrations of kinetin (0, 50, 100 and 150 mg L-1), whereas the sub-plots were occupied by three varieties of spraying wheat (Sham-6, Iba-99 and Bora). The results showed that the spraying of kinetin at a 100 mg L- 1was significantly superior inthe plant height (101.78 cm), flag leaf area (48.32 cm2), number of grains (57.58 grain spike-1), grain yield (6.542 ton ha-1) and dry gluten percentage (8.91%) compared with other concentrations. Also, Iba-99 variety was significant superior inthe flag leaf area (48.67 cm2), number of grains (62.71 grain spike-1), grain yield (7.185ton ha-1) and wet gluten percentage (28.50%) compared with other varieties.We conclude the possibility of using kinetin to improve the performance of bread wheat crop, as well as the possibility of using the Iba-99 variety on a large scale for agriculture in Iraq.

Abstract:

Eight wheat varieties viz. NI-5439. NI-747-19, NI-146. Sonalika, DWR-39, MACS-1967, C-306 and WH-147 were evaluated for their tolerance to both black and brown rusts. All the varieties except NI-5439 and Sohalika have shown reduction in yield due to higher rust intensity. These two varieties, despite suffering heavily form stem and leaf rust infection under artificial epiphytotic condition of inoculation, suffered less so for as the grain yield is concerned. Thus these two varieties can be rated as tolerant.

Abstract:

AbstractThe rumen dry-matter degradation of straw from nine varieties of barley, nine varieties of wheat and seven varieties of hard wheat was studied to provide further information on varietal differences and their relationships with agronomic characteristics.In all the cereals there were significant differences in in situ dry-matter disappearance between varieties. The range of differences was lower in hard wheat varieties compared with the other cereals. There were no significant correlations between straw degradability and plant height, days from sowing to heading and grain production and quality. Lignin concentration was significantly correlated to straw degradability (r = −0·937 in barley, −0·675 in wheat and −0·987 in hard wheat).Leaf had lower concentrations of lignin and higher degradability than stem in barley and wheat but the two fractions were similar in hard wheat straws. The differences in degradation between the most and the least degradable straw varieties of each cereal species were mainly due to differences in degradability of both the fractions whereas the role of leaf and stem proportions was of minor importance.

Abstract:

Wheat is worldwide consumed and contributes significantly to the intake of antioxidants with beneficial healthy effects. In the precise two-year field experiments in 2008 and 2009 two varieties of wheat einkorn, two varieties of emmer wheat and three varieties of spring wheat and in 2009 in addition two other spring wheat varieties, three einkorn varieties and three emmer wheat varieties were evaluated for selenium content and antioxidants &ndash; total polyphenols (TP). Selenium content was determined by atomic absorption spectrometry with hydride generation technique (HGAAS) and total polyphenols with Folin-Ciocalteau assay. Higher selenium content in grain is related to emmer (58.9&ndash;68.4 mg/kg DM) and einkorn (50.0&ndash;54.8 mg/kg DM) varieties; in spring varieties selenium content ranged from 29.8 to 39.9 mg/kg DM. Among the varieties with high TP (expressed in gallic acid equivalents) emmer varieties prevail (584&ndash;692 mg/kg DM), less represented are einkorn (507&ndash;612 mg/kg DM) and spring wheat (502&ndash;601 mg/kg DM) varieties. Among varieties significant differences were determined. TP were significantly higher in emmer wheat varieties and one einkorn and one spring wheat variety. Between TP and Se significant linear correlation was determined (r = 0.709). &nbsp;

Abstract:

Soil-borne wheat mosaic virus (SBWMV) is an important disease of wheat production areas throughout the world, causing a great reduction in wheat and barley yields. The most effective way of controlling the disease is the use of resistant varieties in infested areas. In this study, the effects of SBWMV on yields and some yield components of eight susceptible, one moderately susceptible/resistant and nine resistant varieties were evaluated using data from 9 virus-infested and 6 non-infested sites in Eskisehir, Turkey over 6 years. The susceptible varieties yielded 5.35% more than resistant varieties in non-infested sites, while they gave 28.98% lower yield in infested sites. Significant yield loss differences were observed between the varieties in infested sites. Decreases were also observed in yield components at various levels. This study showed that SBWMV is an important disease, which survives in soil for long periods and causes significant yield decreases in wheat. Recently developed varieties have good resistance to the disease and are recommended to farmers in infested areas. Abbreviations: SBWMV, soil-borne wheat mosaic virus

We examined 35 early, 32 mid-season and 12 mid-late winter wheat varieties on calciferous chernozem soil after sunflower green crop in 2003. We set-up the experiment on small-size parcels, with 4 repetitions. In addition to the favourable agrotechnical conditions, with this year’s extreme ecological conditions the varieties resulted in weaker yields (2500-3200 kg/ha). Our findings have proven that there is a significant difference both between the maturity groups and between the yield potential of varieties with different genotypes, inside each group. Early varieties showed lower yield potentials according to the other two groups. The differences between the various variety’s yields was the smallest in the mid late group (893 kg/ha). Under given ecological and agrotechnical conditions, the following varieties showed the relatively best yields and best adaptability:• early maturing varieties (3200-3700 kg/ha): Mv palotás, KG Magor, Mv Mambo, Mv Emese, GK Margit, GK Tündér, GK Csongrád, GK Attila, Mv Amanda, Ukrainka;• mid season varieties (3300-3800 kg/ha): Győző, GK Marcal, Róna, GK Rába, Buzogány, MF Kazal, GK Mura, Hunor, GK Cipó, Mv Magvas, Mv Vilma, GK Zugoly, Jubilejnaja 50;• mid-late varieties (3200-3600 kg/ha): Maximus, Complet, KG Kunhalom, GK Holló.

The article discusses the issue of frost resistance of varieties and samples of winter wheat sown at different depths, in the extreme conditions of Karakalpakstan. Both a decrease and an excessive deepening of sowing leads to a significant decrease in their resistance to low temperatures, which negatively affects their subsequent survival in the spring-summer period. On the basis of the data, 2 varieties were selected, they turned out to be frost-resistant and differed in good yield and other valuable traits in comparison with the zoned varieties. They were transferred to the State Commission for Variety Testing of Agricultural Crops, under the name "Chimbay" and "Aral".

Abstract:

The article presents studies carried out in 2018–2019 and 2019–2020 in the southern foothill zone of the North-West Caucasus in the fields of the selection and primary seed produc- tion department of the Adygh Research Institute of Agriculture. The aim was to study the actual, biological or potential yield of winter soft wheat varieties cultivated in the region, as well as the ratio of the mass of the grain part and the harvested straw - the yield index. The studied varieties were divided into groups according to plant height: semi-dwarfs (up to 90 cm), short-stemmed (up to 105 cm), medium-sized (up to 120 cm). According to the results of the studies carried out, differences in the studied characteristics were revealed. In the group of semi-dwarf varieties, the grain yield varied from 7,25 to 8,05 t/ha, short-stemmed 7,78–8,91 t/ha, medium-sized 7,34–9,60 t/ha. The highest grain yield was shown by the Vekha variety (9,60 t/ha) belonging to the group of medium-sized varieties, from the short-stemmed Maikopchanka varieties (8,91 t/ha) stood out, Kalym semi-dwarf varieties (8,05 t/ha). The biological yield in the experiment varied from 9,37 to 15,29 t/ha. From semi-dwarf varieties, Grom stood out (14,06 t/ha), short-stemmed varieties – Mafe (10,8 t/ha), medium-sized varieties – Vekha (15,29 t/ha). The difference between the actual and biological grain yield of varieties belonging to the short-stem group was the smallest in comparison with the varieties of the semi-dwarf and medium-grown group. On average, over two years of research, the harvesting index was 46,9–53,2%. Semi-dwarf winter wheat varieties had the maximum value of this indicator. In the group of short-stemmed Grom and Graf varieties, the ratio of the mass of the grain part to the harvested straw varied from 46,8% (Velena) to 50,5% (Alekseich). The harvesting index for medium-sized varieties was at the level of 46,9–51,8%. The Vekha variety, which showed the maximum value, stood out from this group.

Abstract:

The article highlights the specifcs of the formation of varietal resources of winter wheat in Ukraine. It is shown that the creation of new varieties is a long, laborious and expensive material and intellectual process. The scheme of the selection process of winter wheat is complex and includes at least 12 stages, during which various selection methods are used. Breeding work to create one variety takes 6–12 years. Analysis of the structure of the State Register of Plant Varieties Allowed for Distribution in Ukraine revealed that as of 2022, 661 varieties of winter wheat were entered into the Register, including 470 varieties of Ukrainian selection, which is 71.1 % of their total number. Over the past fve years, the number of winter wheat varieties in the Register of Plant Varieties has increased 1.7 times, from 273 in 2017 to 470 in 2022. During this period, varieties of foreign selection entered the Register more actively, which in 2022 amounted to 28.9 % of the total number, while in 2017 they were 19.9 %. The majority of created varieties – 43.4%, are recommended for distribution in all soil and climatic zones of Ukraine – Steppe, Forest-Steppe and Polissia. By groups of ripeness, the largest number of varieties is 43.5 % medium-ripe and 37.2 % – medium-early varieties. The analysis of the activity of the originators of varieties of domestic breeding showed that the Institute of Plant Physiology and Genetics of the National Academy of Sciences of the Russian Academy of Sciences is the leader, and in 2022, 102 varieties or 21.7 % of the total number of domestic varieties were entered into the Register. The main direction of the selection work of this institute is the creation of plastic varieties of winter wheat for distribution in all zones of Ukraine – steppe, forest-steppe and Polissia, the share of these varieties from their total number is 61.8 %, mainly these are mid-early and mid-ripening varieties. According to the level of productivity and the direction of use, the wheat varieties of the Institute of Plant Physiology and Genetics of the National Academy of Sciences of Ukraine are conditionally divided into two groups: short-stemmed, high-intensity varieties, which under favorable climatic conditions and intensive cultivation technologies are able to form a grain yield of up to 10 t/ha and more, and medium-growing varieties of universal use, which in extreme growing conditions exceed the yield of high-intensity varieties. Key words: Register of varieties, selection process, maturity groups, distribution of varieties, domestic selection.

Abstract:

As regards wheat varieties constituting a natural ploid series the issue of analysing diploid, tetraploid and hexaploid species is topical since ancient varieties can play significant roles in contemporary agriculture as well. Seventeen winter wheat varieties, out of which 2 diploid varieties carried genome A, 9 diploidic types had genomes AB, two varieties had genomes AG and four varieties were hexaploid ones with genomes ABD, were analysed from the point of view of their amino acid compositions. The amino acid contents of Asp, Thr, Ser, Glu, Gly, Ala, Cys, Val, Met, Ile, Leu, Tyr, Phe, His, Lys, Arg, Pro (a total of 17) were determined in the varieties listed above. It has been found that the amino acid contents of the grains genotype AA Triticum boeticum and T. monococcum exceeded the amino acid content of T. aestivum in respect of all the amino acids analysed in this experiment, with Glu being the only exception. In comparison with the aestivum wheat, essential amino acid contents showed a similarly favourable picture in the diploidic varieties mentioned. As regards type AB tetraploid varieties excesses of 13-16%, in comparison to the aestivum wheat, were found in essential amino acid contents. The amounts of non-essential amino acids in all the winter wheat varieties showed decreases irrespective of the ploid level. What concerns the total amino acid content, all the winter wheat varieties with the exception of T. monococcum (A), T. dicoccoides (AB) and T. dicoccum (AB) contained less amino acid than the aestivum wheat. All the monocarbonic acid and aromatic as well as heterocyclic amino acid contents of the wildly growing Triticum boeticum (A) and the grown Triticum monococcum (A) (with polaric, apolaric R groups, diamino radicles) exceeded the same contents of T. aestivum. The value of the monoamino-dicarbonic acid, however, was lower in our experiment.

Abstract:

Using mycorrhizal fungi known to colonize wheat, the mycorrhizal dependence of various small grains including modem wheat varieties, primitive wheat lines, and wheat ancestors was studied. With the exception of the United States cultivar Newton and the German cultivars Apollo, Kanzler, and Sperber, dry weight of eight other modern wheats from the United States and Great Britain were increased by 29–100% following inoculation with mycorrhizal fungi. All landraces from Asian collections or early introduced American cultivars were also dependent on the symbiosis, with dry weight increases averaging 169 and 55%, respectively. All wheat ancestors of the AA and BB genomes (except Aegilops speltoides) benefitted significantly from the symbiosis, whereas no benefit was observed for ancestors of the DD genome, tetraploid wheats of the AABB or AAGG genomes, or in the hexaploid ancestor Triticum zhukovskyi (AAAAGG genome). These differences in mycorrhizal response of the ancestors, lines, and cultivars were highly correlated with root fibrousness ratings. When the fungi used as a combined inoculum in the previous experiment were inoculated individually onto selected plant species or cultivars, 6 of the 10 isolates stimulated growth of Andropogon gerardii, a highly dependent grass species, and 8 of the 10 stimulated the growth of 'Turkey' wheat. In contrast, none of the isolates positively affected growth of 'Newton' or 'Kanzler' wheat cultivars, and in fact several fungi decreased the biomass produced by these two cultivars. These studies have demonstrated a strong genetic basis for differences in mycorrhizal dependence among cultivars. A trend for greater reliance on the symbiosis in older cultivated wheats than iin wheat ancestors or modern wheats was also observed. The depression in growth associated with certain mycorrhizal fungi and wheat cultivars demonstrates that colonization of roots does not guarantee benefit from the symbiosis. Key words: root fibrousness, growth response, vesicular–arbuscular mycorrhizae.

Abstract:

Wheat breeding continues to be an important component of agricultural innovations in the Great Plains region of the US. This paper reviews Oklahoma’s wheat breeding program over the past several decades with an emphasis on the economic aspects and planning of future breeding strategies. Over the past century, Oklahoma’s wheat yields have increased but the productivity gains have been offset in part due to increased yield variability. The shift to improved wheat varieties has resulted in increased susceptibility to plant disease and pest pressure. While a few varieties introduced over the past few decades have dominated the wheat seed market, recent trends indicate producers are adopting a more diverse range of wheat varieties. Producers’ concerns have expanded beyond demands for high yielding varieties to include more market oriented needs to increase protein content and test weight. This paper identifies several key policy instruments that Oklahoma stakeholders and policy makers should consider when planning future breeding strategies. A critical need is to assist Oklahoma producers in adapting to climate change by developing drought and heat resistant wheat varieties. Marketing new varieties would be improved and revenue increased if more innovative pricing structures were adopted to better align producers’ willingness to pay with seed development costs, which could then be re-invested in breeding. Research budgets, which have remained stagnant in real terms, will need to be increased to adequately address producers’ needs into the 21st century.

Abstract:

During 1997–1998, the reaction of the collections of winter and spring wheat varieties to Tilletia caries was determined. In both years the most diseased winter varieties were Simona and Sparta, the least diseased were Samara and Ilona. High variability in the level of infection was observed in some varieties (VIada, Estica, Regina, Vega). No winter wheat variety was completely resistant. The most diseased spring wheat variety was Alexandria in both years, while Grandur showed no infection. High variability in the level of infection was observed in the special trials with cv. Ina and Contra. In trials of the efficacy of seed dressing against T. caries and T. laevis there was variability only in the controls, but not in dressed variants.

Abstract:

Protein composition of the grain storage proteins (evaluation using electrophoresis in polyacrylamide gel – the SDS-PAGE method) and selected parameters of bread-making quality in a set of 6 winter wheat varieties from organic and conventional growing in Central Bohemia (elevation 295 m a.s.l.) were evaluated during a two-year experiment (2004 and 2005). In comparison with the varieties from organic growing, wheat varieties from the conventional growing were characterized by twice the percentage of High Molecular Weight (HMW) glutenins, responsible for dough elasticity (conventional wheat in average 25.22%, organic wheat 12.71%). At the same time, varieties from conventional growing generally reached higher, more positive values of crude protein content and wet gluten content in grain dry matter, sedimentation index by Zeleny and yield of bread. On the other hand, wheat varieties from organic growing were mainly characterized by significantly higher percentage of nutritionally valuable albumins and globulins (organic wheat in average 17.69%, conventional wheat 7.33%). In both systems of growing the highest percentage of HMW glutenins was determined in varieties from the quality group E (elite, the most suitable for bread-making), while the varieties from the quality group C (wheat unsuitable for bread-making) reached the highest percentage of residual albumins and globulins.

This paper deals with the influence of Mg, N and the content of chlorophylls and carotenoids on photosynthetic productivity of two new genotypes of winter wheat, Lara and Perla, at two localities, Donji Miholjac and Kutjevo, during the vegetation periods 1997/1998 and 1998/1999. The applied parameters were determined by standard methods. The results showed effects of Mg concentration on all examined parameters with the exception of chlorophyll b content. The highest correlation coefficient was with the N concentration, significant correlation between the leaf area and N concentrations and between the leaf area and chlorophyll a. Statistical analysis showed very significant relationship between the content of organic matter and examined parameters with a large number of significant correlations. The most important correlation was found between the content of organic matter and N concentration, and between chlorophyll a, chlorophyll b, carotenoids and the content of organic matter. The link between N, Mg and other examined parameters was firm and significant as well as under strong influence of external factors.

Abstract:

For field experiments in an effort to elucidate functions of the wheat lectin (wheat germ agglutinin, WGA), the establishment of varieties sharply contrasting in the lectin content is very important. As the starting point for solution of this problem we studied the WGA variability in the seeds of 33 spring wheat varieties obtained in two different breeding centers: Saratov's and Kharkov’s those. The vari ability in response to environment for Saratovskaya 29 was also estimated. It was found that the maximal variability in the WGA seed content is intrinsic to varieties of soft wheat originated from Saratov's breeding center. WGA is known to involve in the wheat adaptation to stresses and to interact with root microflora; taking into account this fact we propose that the high variability of wheats from Saratov region is associated with more continental climate in which the breeding of the tested varieties was performed.

MOLNÁR-LÁNG AGRICULTURAL RESEARCH INSTITUTE OF THE HUNGARIAN ACADEMY OF SCIENCES, MARTONVÁSÁR, HUNGARY Received: August 15, 2000; accepted: October 15, 2000 The translocation which involves the substitution of the short arm of the 1R rye chromosome for the short arm of the 1B wheat chromosome by means of centric fusion has exercised an enormous influence on the world’s wheat breeding. Since the first mention of this translocation in 1937 the incidence of the 1RS/1BL translocation has been reported in connection with several hundred wheat varieties. Varieties carrying the translocation possess a chromosome segment which includes the resistance genes Sr31 (stem rust, Puccinia graminis), Lr26 (leaf rust, P. recondita), Yr9 (yellow rust, P. striiformis), Pm8 (powdery mildew, Erysiphe graminis) and Gb (aphid, Schizaphis graminum). The present paper investigates the occurrence of the 1RS/1BL translocation in wheat varieties bred in Hungary in recent years. It was found that 35 (53%) of the 66 Hungarian-bred wheat varieties registered in Hungary between 1978 and 1999 carried the 1RS/1BL translocation.

Abstract:

US wheat varieties are examined for differential disease resistance between public and private varieties, an issue for critics of plant intellectual property. Analysis using disease resistance rankings of wheat varieties from Kansas and Texas indicate that private varieties are as or more resistant. This finding was further confirmed with two years of Texas data. Thus, the results from the study reject the criticism of private breeding activities that they are more susceptible to disease compared to public varieties. However, private varieties resistance is incorporated from public offerings so that productive private wheat breeding is partly derivative.

Abstract. Each soil-climatic zone should be provided with the most adapted varieties of agricultural crops. The Middle Cis-Urals is characterized by a short growing season, low-humus acidic soils. However, due to global warming, the sum of active temperatures in the region exceeded 2000 °C and made it possible to grow not only early-ripening, but also mid-ripening varieties of spring wheat, which have a greater productivity potential. The purpose of the study is a comparative assessment of spring wheat varieties of different ripeness groups according to the nature of the development of the above-ground mass, the formation of yield and its components. Methods. Zonal tests were carried out for three years on acidic soddy medium podzolic medium loamy soil. We tested 10 varieties of early, mid-early and mid-ripening groups. The field experience had accounting plots with an area of 1.05 m2 and their sixfold repetition. Results. It has been established that the mid-early varieties Omskaya 36 and Kalinka, as well as the mid-ripening varieties Simbirtsit, Likamero and Chernozemnouralskaya 2, significantly exceeded the yield of the early ripe variety Irgina by 13, 20, 15, 13 and 31%, respectively. In addition, varieties Chernozemnouralskaya 2 and Kalinka showed an average variation in yield (V = 12.5 and 19.7 %, respectively). The mid-ripening varieties Simbirtsit, Likamero and Chernozemnouralskaya 2 compared with the Irgina variety had a significantly lower straw content ratio by 18, 29 and 17 %, respectively. The variety Chernozemnouralskaya 2 stood out among other varieties in coefficient of productive tillering, exceeding the Irgina variety by 15.5 %. Varieties Kalinka and Simbirtsit had a greater mass of 1000 grains, respectively, by 3.9 and 3.0 g than that of the Irgina variety (27.7 g). The scientific novelty of the conducted research lies in the comparative assessment of the formation of yields by spring wheat varieties of different ripeness groups on acidic low-humus soil.

Abstract:

History of wheat breeding in Latvia A gene pool of Latvian winter and spring wheat (Triticum aestivum L.) has been created over a very long period, by collection, evaluation and selection of local genetic resources, and investigation of varieties and breeding lines from other countries in the world. It is not only a historical collection, but also serves as the foundation for research and plant breeding. National wheat germplasm is the framework for creating competitive winter and spring wheat varieties of grain with high yield, resistant to lodging and diseases, and quality acceptable for producers in the Baltic agroclimatical region. In Latvia, from 1920 to 1990, the selected wheat varieties were not stable pure lines, but mostly population varieties. After accession to UPOV (International Union for the Protection of New Varieties of Plants), the requirements for new varieties have changed, and only distinct, uniform and stable varieties, characterised by high economical value are registered in Plant Catalogues. To implement wheat breeding programmes it is necessary to improve breeding methods by plant tissue culture and production of doubled haploids (DH). During 90 years, 16 winter and 11 spring wheat varieties of bread wheat (Tr. aestivum L.) have been created at Priekuļi and Stende and introduced in the market. The achievements of several generations of Latvian wheat breeders are reviewed in this paper.

Abstract:

The effects of vernalization and photoperiod on times from planting of seedlings to ear emergence were measured in 68 Australian and 49 overseas varieties of wheat, comprising a broad spectrum of genetic material, in a glasshouse in Canberra (latitude 35�S). Vernalization was carried out by growing germinated seedlings in the dark at 1-2�C for 6 weeks. Long photoperiods (16 h) separated unvernalized plants into two distinct groups, corresponding to commonly recognized spring and winter types. Responses to vernalization were generally small under natural photoperiods (11-15 h), but much more pronounced in long photoperiods, particularly with winter wheats. In a second experiment, 24 varieties of wheat gave widely different responses to vernalization treatments. With 8 weeks' vernalization and long photoperiods, all varieties reached ear emergence within 66 days, but in some winter wheats 4 weeks treatment had little effect and 6 weeks gave incomplete vernalization. Under the conditions of these experiments, Australian wheats showed a wide range of responses to photoperiod and a narrow range of responses to vernalization compared with overseas varieties. The need to investigate the control of flowering time in obtaining varieties suited to the high-rainfall zone of Australia is discussed.

Abstract:

Field experiments were conducted at three locations in Alberta to determine the relative competitiveness with wild oat (Avena fatua L.) of three hard red spring (HRS) and three Canada prairie spring (CPS) wheat (Triticum aestivum L.) varieties and a semidwarf hull-less barley (Hordeum vulgare L.) (Falcon), and normal height general purpose barley (AC Lacombe). Crop variety significantly affected crop yield loss, wild oat shoot dry weight and wild oat seed yield (competitive indicators). AC Lacombe barley was consistently more competitive than Falcon barley or any of the wheat varieties, while the HRS wheat varieties were mainly more competitive than the CPS varieties. Falcon barley was generally similar in competitiveness to the CPS wheat varieties. Differences among varieties in crop plant density at establishment correlated significantly with the competitive indicators suggesting that this factor contributed to the differences in competitiveness among the varieties. Crop density tended to be higher with the more competitive AC Lacombe barley and HRS wheat varieties than with the less competitive Falcon barley and CPS wheat varieties. Variety and seeding rate did not interact significantly but intentionally increasing the seeding rate improved the competitiveness of all varieties. Key words: Hard red spring wheat, Canada prairie spring wheat, crop seeding rate, hull-less barley, semi-dwarf wheat and barley

Abstract:

In terms of differentiation of agricultural enterprises by the level of intensification of grain production it is necessary to cultivate varieties that are most adapted and cost-effective for specific levels of technologies of growing spring wheat. This is confirmed by the ecological variety testing, which was carried out in different soil - climatic and technological conditions. In the Vladimir niiskh on gray forest soils under normal technology, the new variety of mA’am was characterized by the highest yield, resistance to lodging and disease. In the competitive variety testing on average for 10 years, he provided a yield of 37.7 C / ha (higher than the best studied in the experience of varieties by 5.9-10.3 C/ha) with resistance to lodging 8.4 points on a 9-point scale. The maximum yield varieties in 2009 was 62.0 q/ha. During the last 5 years of competitive variety trials the most stable and productive years was a kind of heater, which on average for 2013-2017 exceeded the grade’am 4.6 t/ha in the same agricultural background. Among studied varieties of spring wheat the highest yields provided a variety Rook, cultivated on intensive technology: high soil fertility in the Republic of Belarus yields reached 99,0 kg/ha in 2013, and in Yaroslavl, NIIZK - 80,0 kg/ha in 2017 In the Vladimir research Institute of agriculture at high doses of fertilizer, but without the protection of plants from diseases, pests and lodging in 2017 received a yield grade of 73.0 kg/ha.

Abstract:

Selection for drought tolerance typically involves evaluating genotypes for either high yield potential or stable performance under drought stress. In order to select drought tolerant varieties of bread wheat an experiment was conducted in a randomized complete block design (RCBD) with two replications during the growing season 2014-2018. Eight drought tolerance indices including stress tolerance index (STI), geometric mean productivity (GMP), mean productivity index (MP), stress susceptibility index (SSI), tolerance index (TOL), yield index (YI), yield stability index (YSI) and drought resistance index (DI) were calculated and adjusted based on grain yield under drought years (Ys) and favorable years (Yp). Result of study showed significant positive correlation between grain yield in the stress condition (Ys) with indicators STI, GMP, TOL, MP, and DI, accordingly they are discriminating drought tolerant genotypes at the same manner. Wheat varieties Darkhan-172, Darkhan-72, Altaiskaya-325, Altaiskaya-70, Darkhan-181 has a high yield potential.
