Full textAbstract:
The duration of the growing season is an important, adaptively significant indicator for any crop variety. In wheat breeding, a reliable criterion for determining the maturity group of a variety is the ear formation period. The purpose of the study was to determine the ear formation period of soft winter wheat varieties of various ecological and geographical origins in the conditions of the forest steppe of the Middle Volga region, and also to determine its effect on yield. Among the studied varieties of wheat from the world collection, German varieties were characterized by late ripeness, wheat from China, Japan, Bulgaria and the North Caucasus region of Russia by early ripeness and mid-ripeness, - varieties from the Siberian region of the country by mid-ripeness. Ukrainian cultivars were represented by wheat of different maturity groups. It has been found in the studies that under varying environmental conditions in different years early ripening, mid-early, mid-ripening and mid-late wheat can be highly productive. A well selected system of ripening varieties of soft winter wheat (65–70 % mid-ripening, 25 % mid-early and early-ripening, 5–10 % mid-late) will make it possible to use favorable environmental factors with great efficiency and withstand environmental stresses.

In the Middle Urals the middle-ripening varieties of spring soft wheat with gluten content of 22–24% and the middle-early and early ripening varieties of spring soft wheat with gluten content of 26–34% are able to form kernels suitable for bread baking of the first, second and third classes. Nowadays a comparative characteristic of the grain quality of the main varieties developed by the of the selection of the Ural RIA included in the State List of the Breeding Achievements in the Volga-Vyatka Region and their ability to form food grain suitable for bread baking is of great practical interest. In the Krasnoufimsky breeding center there were studied 11 spring wheat varieties included in the State List of the Breeding Achievements in the Volga-Vyatka region in the 2013 and 2016 years of arid conditions (90–100 mm of precipitation, 17.0–17.5 ºC of average daily air temperature) and in the years 2014 and 2015 of excessive moisture (294–423 mm of precipitation and 15–16 ºC of average daily air temperature). The early ripening varieties “Irgina” and “Iren” (71–94 days of vegetation period) formed an average yield of 2.94 t/ha. The middle-early ripening varieties “Ekaterina”, “Gornouralskaya”, “Svecha”, “Bazhenka”, “Zlata” (75–98 days of vegetation period) produced 3.32 t/ha.The middle-ripening varieties “Krasnoufimskaya 100”, “Ekada 70”, “Simbirtsit”, “Omskaya 36” (90–94 days of vegetation period) produced 3.55 t/ha. The most productive ones are “Iren” (3.05 t/ha), “Ekaterina” (3.64 t/ha), “Ekada 70” and “Simbirtsit” (3.70–3.78 t/ha). Food grain of the first class (with gluten content of more than 32%) was formed by the varieties “Irgina”, “Iren”, “Bazhenka”; the rest varieties formed the second class grain (with gluten content of more than 28%). The ranking method by seven indicators of grain quality allowed us to determine the average rank and to identify the varieties “Irgina” and “Iren” with the highest baking properties (average rank of 1.0–1.7). They are the most promising varieties for the production of food grains in the conditions of the Middle Urals. It is not advisable to use the middle-ripening varieties “Ekada 70” and “Simbirtsit” for this purpose as the average rank of their quality indicators is 7.0–7.1.

Full textAbstract:
The current study was carried out in order to create an early-ripening variety of spring bread wheat with productivity at the level of middle-early or higher, the most adapted to the specific conditions of the Middle Urals. The estimation of the breeding material was carried out in the fields, the soils of which are typical for the Sverdlovsk region and Permsky Krai. During the years of the study, the agroclimatic conditions differed along the growing season. There have been established the dry year of 2016 (90 mm of rain, GTC 0.6) and the moisture years of 2014, 2015, 2017–2019 (with precipitation amount of 247–448 mm, GTC 2.0–3.2). The crossings were carried out between the middle-ripening variety ‘Omskaya 35’ (mother) and the early- ripening variety ‘Iren’ (father). There has been developed the variety that combined high productivity and early maturity. The average productivity of the new variety ‘Ekstra’ in the Competitive Variety Testing in 2014–2019 was 4.07 t/ha, which is on 0.55 t/ha higher than the standard variety ‘Iren’, the maximum productivity was 5.0–6.1 t/ha (2019). The new variety has exceeded the values of the standard variety in such yield structure elements as “seed weight per head”, “1000 grain weight”, “grain content per head”; the accumulation of seeds per day of growing season was 14.2% and at 1 mm of precipitation the value improved till 15.2%. In the ecological testing the variety ‘Ekstra’ exceeded the varieties ‘Iren’, ‘Irgina’ from the State List of Breeding Achievements in the Volga-Vyatka region on 0.56–0.80 t/ha and the middle-early ripening varieties ‘Gornouralskaya’, ‘Bazhenka’, ‘Svecha’, ‘Zlata’ on 0.44–0, 55 t/ha. The variety ‘Ekstra’ is characterized by better energy efficiency parameters than ‘Irgina’, ‘Iren’, ‘Gornouralskaya’, ‘Zlata’. The excess was 9.2–21.9% in terms of total energy in the harvest per hectare, 16.0–40.6% in net energy income, and 4.7–13.1% in bioenergy ratio. The variety reduced energy consumption for the production of 1 ton of grain by 9.5–11.5%. There has been determined a significant advantage of the variety ‘Ekstra’ in terms of the general adaptability, stability, and breeding value of the genotype. In 2020 the variety was included into the State List of Breeding Achievements in the Volga-Vyatka region, Ural, West Siberian regions of the Russian Federation. The variety ‘Ekstra’ has the same parameters of productivity, yield structure elements, adaptability, the accumulation of seeds per day of growing season and per 1 mm of precipitation, energy efficiency of cultivation, as the middle-early ripening standard variety ‘Ekaterina’.

Full textAbstract:
At present, the results of research of the ripeness dynamics of cereal for harvesting it in the earlier periods in the condition of Uzbekistan. During the researches, quality indicators were studied of wheat sorts of middle and late ripening “Krasnodar-99” and “Kroshka” as well early ripening “Chillaki” in wax (biological) ripening and technical (complete) ripening periods and the grain that was harvested in early periods. It was known that the grain of wheat becomes empty by results of experiments if it is harvested 16 earlier than complete ripeness. When it is harvested 12 days earlier, the grain ripens more completely than the previous. However, its fullness does not become at enough level. If the cereal is harvested 8 days earlier than complete ripeness, namely when it is harvested in the wax ripeness period, the fullness of the grain does not become less than the fullness of the grain that is harvested after complete ripeness.

Full textAbstract:
The work presents the results of research into the yield and quality of grain obtained from crop varieties of different maturity types, namely spring common wheat varieties (mid-early Pamyati Aziyeva, mid-late Baganskaya 95 and Omskaya 28), spring barley (early-ripening Bagan, mid-ripening Acha and Signal) and spring oats (early-ripening Krasnoobsky, mid-ripening SIG, mid-late Ural 2). The study was conducted in the conditions of the steppe zone of Western Siberia (North Kulunda), the climate of which is extremely continental, and is characterized by signifi cant variability of agrometeorological conditions of the vegetation period by years and a drought during the fi rst half of summer. It was established that sowing of midripening and mid-late varieties of wheat and barley resulted in the increase of the grain yield by 0.47-1.07 t/ha or by 24-30%, compared with the more early-ripening varieties. Among various biotypes of oats, the highest yields of grain were formed by sowing of the mid-ripening variety, which was by 0.60-0.87 t/ha or 19-30% higher than the early and mid-late varieties, whereas the highest yield of green mass was achieved by sowing of the mid-late variety. All varieties of barley, oats and mid-early wheat were characterized by signifi cant variability in grain yields by years (with coeffi cient of variation being 24-38%), while midlate varieties of wheat were characterized by medium or small variability in grain yields (coeffi cient of variation being 3-12%). The content of crude gluten in the grain of wheat varieties varied considerably depending on agrometeorological conditions (coeffi cient of variation being 20-25%). On average, over the years of research, the highest content of gluten (34.0%) was in the grain of the mid-early variety Pamyati Aziyeva, the lowest content (27.4%) was in the mid-late Baganskaya 95. The maximum amount of crude gluten in the wheat grain (33.6-40.0%) was observed in the dry year, the minimum (19.9-26.4%) was in the year with favorable humidity. The content of crude protein in the barley grain varied in the experiment from 11.6 to 14.9% (coeffi cient of variation being 9-14%) and did not differ signifi cantly by varieties (12.5-12.9%). The greatest amount of crude protein in the grain of all varieties of barley (13.7-14.9%) was recorded in the dry year.

Full textAbstract:
Creation and introduction into production new high-yielding and early ripening varieties of soft winter wheat adapted to certain weather conditions are the principal ways to increase yield and improve general harvest volumes. A properly selected variety is one of the most effective ways of achieving crop yield improvement for any farm. To realize the potential for increasing yields, it is crucial to bear in mind specific soil and climatic conditions. The aim of the research was to characterize a new variety of winter soft wheat ‘Podarok Krymu’ by economic and biological qualities, as well as morphological characteristics. Soil of the experimental plot – chernozems ordinary with a thick humus layer (up to 140 cm). The meteorological conditions during the years of research were quite diverse, which made it possible to evaluate the new variety by a set of economically valuable features. The studies were carried out in 2015–2019 on the experimental fields of the scientific crop rotation of the Department of Winter Wheat of State Scientific Establishment “Agricultural research center “Donskoy” (SSE “ARC “Donskoy”). The object of the research – a new variety of winter soft wheat ‘Podarok Krymu’. Winter soft wheat variety ‘Don 107’ was used as a standard. Preceding crop – corn for grain. The accounting area of the variety test plot – 10 m². Field experiments were replicated six times. In 2019, variety ‘Podarok Krymu’ was submitted for State Variety Testing by SSE “ARC “Donskoy” together with the Research Institute of Agriculture of Crimea. This variety has a high potential for grain productivity. The average yield in the competitive variety testing was 7.71 t/ha (preceding crop – corn for grain), which is 0.39 t/ha higher than the average yield of standard variety ‘Don 107’. According to the length of the growing season, the variety belongs to the early maturing group; its ears emerge and kernels ripe three days earlier than that of the standard. The high and stable yield of the new variety is ensured by its tolerance to drought and heat, increased winter hardiness and resistance of plants to frost, as well as resistance to the main diseases typical in the regions where studies are being conducted. Since the autumn of 2020, ‘Podarok Krymu’ has been studied to cultivate it in the North Caucasian, Lower Volga and Central Black Earth regions of the Russian Federation.

Our research was carried out at University of Debrecen Centre for Agricultural Sciences Faculty of Agriculture Institution of Plant Sciences Látókép Research Institute through the breeding year of 2003/2004, 2004/2005 and 2005/2006 using cherrnozem soil. In our research we tested 14 chosen autumn wheat varieties during the three crop years.The different varieties showed very dissimilar ability of resistance against diseases through the three crop years. We could observe both susceptible and resistant varieties. Susceptible varieties got diseases even in favourable crop years. The observed winter wheat varieties showed higher susceptibility against helminthosporium (21.8%) and leaf rost (16.4%). Among the 14 varieties we experienced the least susceptibility in the case of ‘Gaspard’ and ‘GK Kalász’. The research showed that the disease of fusarium undoubtedly depends on the features of the crop year.In terms of stem solidity we experienced big differences. Among all the observed winter wheat varieties the mid-late ripening ‘Gaspard’ showed the best results in the average of the three years, only 5.3% was beaten down.The three ripening group of the winter wheat showed the following average yield in the average of three years: 7065 kg/hectare (early ripening varieties), 7261 kg/hectare (late ripening varieties), 6793 kg/hectare (mid-late ripening varieties). Among all the observed varieties the early ripening ‘Flori 2’ produced the biggest yield (7692 kg/hectare).During the three crop years we reached very different amounts of yield which means that weather conditions had a telling affect on yield. In 2004 we reached an excellent average yield in all the tree breeding groups because of the favourable weather conditions. In 2005 we had a moderate amount of yield because of the unfavourable weather conditions of winter. The year of 2006 showed the smallest amount of yield which is due to the fact that the plant grew less thick than usually.There were significant differences among the observed varieties in the term of yield, which can be attributed to dissimilar biological basics.One of he most important questions is the yield stability of the varieties. We had extremely different results at this field. Speaking in general terms we can state that both weather conditions and genetical abilities have a determining effect on yield. In the case of winter wheat varieties the rate of yield fluctuation was quite big, moving in the interval of 33.7-70.3%. Among all the observed varieties ‘Gaspard’ showed the best yield stability (33.3%).

Full textAbstract:
The influence of sowing method and plant density on the biomass of spring wheat and Persian clover was evaluated. In a pot experiment conducted in three series during the years 2010–2012, plants were cultivated as mixed and pure crop at higher (consistent with agronomic recommendations) and lower density, decreased by 20% compared to it. Dry mass accumulation tests for both species were conducted during the following wheat growth stages (BBCH): leaf development (12–14), tillering (21–23), stem elongation (31–32), inflorescence development (54–56), and ripening (87–89). Based on the results obtained, the biomass growth rate for both species in question was also determined. It was shown that the mass of shoots of spring wheat cultivated as mixed crop was lower than that of wheat shoots grown as pure crop during the stem elongation and ripening stages. Mixed sowing limited aboveground accumulation in the heads and grain the most and in the stems the least. During the leaf development and stem elongation stages, the wheat presented a more pronounced response to the presence of clover expressed by biomass decrease in case of the treatment with lower plant density and during ripening in the treatment with recommended plant density. In case of both sowing methods and plant densities, the mass of wheat roots was similar. Biomass accumulation in Persian clover shoots and roots in mixed sowing was lower than in pure crop during the entire growing period. The wheat limited biomass accumulation of Persian clover in inflorescences the strongest and in the roots the least. The spring wheat growth rate in both sowing methods was similar as opposed to Persian clover in the case of which a decrease in the growth rate was observed in the mixed crop during the generative development period.

Full textAbstract:
Maize is one of the mostly consumed grains in the world. It possesses a greater potentiality of being an alternative to rice and wheat in the near future. In field condition, maize encounters abiotic stresses like salinity, drought, water logging, cold, heat, etc. Physiology and production of maize are largely affected by drought. Drought has become a prime cause of agricultural disaster because of the major occurrence records of the last few decades. It leads to immense losses in plant growth (plant height and stem), water relations (relative water content), gas exchange (photosynthesis, stomatal conductance, and transpiration rate), and nutrient levels in maize. To mitigate the effect of stress, plant retreats by using multiple morphological, molecular, and physiological mechanisms. Maize alters its physiological processes like photosynthesis, oxidoreductase activities, carbohydrate metabolism, nutrient metabolism, and other drought-responsive pathways in response to drought. Synthesis of some chemicals like proline, abscisic acid (ABA), different phenolic compounds, etc. helps to fight against stress. Inoculation of plant growth-promoting rhizobacteria (PGPR) can result to the gene expression involved in the biosynthesis of abscisic acid which also helps to resist drought. Moreover, adaptation to drought and heat stress is positively influenced by the activity of chaperone proteins and proteases, protein that responds to ethylene and ripening. Some modifications generated by clustered regularly interspaced short palindromic repeat (CRISPR)-Cas9 are able to improve maize yield in drought. Forward and reverse genetics and functional and comparative genomics are being implemented now to overcome stress conditions like drought. Maize response to drought is a multifarious physiological and biochemical process. Applying data synthesis approach, this study aims toward better demonstration of its consequences to provide critical information on maize tolerance along with minimizing yield loss.

Proteins are not just interesting and significant in food in their intact or even aggregated or complexed states, but often lend their greatest value to food by their disappearance. For example, in cheese, as we discussed in the last chapter, proteins are critical for the coagulation of milk and conversion into curd, and cheesemakers choose the enzymes they use to cause that coagulation specifically for their lack of other impact on the milk protein casein. However, once the cheese is made, the intactness of the casein abruptly becomes a liability, in a sort of cosmic ingratitude, and indeed the cheese will not be considered fit to eat until it is at least partially gone. The reason for this is immediately apparent if the freshly made cheese (of just about any variety) is tasted. Does it taste like cheese? Only if you like your cheese bland and flavored almost entirely of salt. Does it have the texture of cheese? Only if you think cheese should take quite a while to chew while savoring its boring saltiness. This is the taste and flavor of (salted) intact casein curd. So, no one eats cheese in this state, and almost every variety of cheese, from Accasciato to Zamorano, is held for at least some time after manufacture to undergo what is called ripening, during which it develops the flavor and texture we will expect it to have. In the case of the Parmesan shown in Figure 3.1, the crumbliness we associate so closely with this cheese is achieved by a combination of breakdown of the protein network over very long ripening times (often 12 months to 2 years), and a parallel drying out to low-moisture contents (which also concentrates the wide range of compounds produced during such long ripening to give a very strong and piquant flavor). Interestingly, almost all freshly made cheeses enter the ripening stage with similar flavor, but they leave with a ridiculously wide variety of characteristics.

Only three weeks after the Hiroshima Peace Concert, Bernstein returned to Japan to tour with the Israel Philharmonic Orchestra (IPO). The days Bernstein and Hashimoto spent together during this tour were manifestations of their ripening relationship, both professional and personal. The IPO concerts took place amidst the volatile conflict in the Middle East, but the music Bernstein and the orchestra delivered clearly spoke across borders, and especially the performance of Mahler’s Symphony no. 9 became legendary. While many critics lauded the performance in the press, the most eloquent expression of what Bernstein communicated was Kazuko Amano’s letter to the maestro.

This undistinguished, productive, drought resistant, vigorous white grape, Airén, from the La Mancha region of Spain, was said to be the most widely planted grape in the world. In part the justification for this claim relies upon the observation that it is planted at a very low density! Except for its use in blending to make other wines “lighter,” it has not found wide accep¬tance. In part, it appears that its lack of popularity is the result of what is reported to be a mild, neutral flavor, and advertising has not pushed wines produced from it to the fore. Although it is now common to attempt to analyze the headspace (or ullage) in bottled wine (as well as the wine itself ) by chromatographic and mass spectrometric techniques it is less common to find that the grapes (skin, must, and seeds) are also subjected to such analysis. Nonetheless, the phenolic composition of V. vinifera var Airén was subjected to just such analysis during ripening from véraison to “technological” maturity (i.e., maturity which might actually be earlier than harvest, the latter being the decision of the viticulturist and vintner). The analysis of the ethyl ether extract of macerated skins, seeds, and accumulated solids (the pomace) was undertaken. Procyanidins and anthocyanins which would (the authors claim) interfere with subsequent analysis would not move into the ether phase. It was also found (using controls) that other highly polar materials (e.g., carboxylic acids) were only poorly extracted from the macerated skins and seeds. The isolated compounds and some information about their sources are provided in Figures 14.1 and 14.2. The analysis of the seeds, skin, and must did lead to the conclusion that “the maximum concentrations of benzoic and cinnamic acids and aldehydes and flavonol aglycones and glycosides at the end of the ripening period did not coincide with the minimum concentrations of the flavan-3-ols and hydroxycinnamic tartaric esters.” Depending upon what was sought, this information might thus affect decisions concerning the harvest date.

Full textAbstract:
The article deals with the effect of nitrogen fertilizer on the yield of different cultivars of winter wheat. Field experiments were conducted in 2011–2013 at the Experimental Station of Aleksandras Stulginskis University in carbonate shallow gleyic leached soil, (Calc(ar)i-Epihypogleyic Luvisol). The object of the investigation was winter wheat cultivars ‘Zentos’ and ‘Ada’. In sowing time the wheat was treated with granular superphosphate (P60) and potassium chloride (K60), and in spring, after the vegetative growth had resumed, in tillering time (BBCH 23–15) with ammonium nitrate (N60). Additionally, foliar fertilizer urea solution was used: N30, N40 at booting stage (BBCH 34–36) and N15, N30 at milk ripening stage (BBCH 71–74). It has been established that application of nitrogen fertilizer at booting and milk ripening stages increased the yield of wheat cultivars ‘Zentos’ and ‘Ada’ (0.06–1.74 and 0.41–1.74 t ha–1). The correlation and regression analysis confirmed that wheat grain yield statistically significantly correlated with nitrogen fertilizer application rates. The correlative relationships were very strong (r = 0.983 and r = 0.987). Irrespective of additional fertilization, genetic properties of the cultivars also had influence on the yield.

Full textAbstract:
The paper investigates the effect of nitrogen fertilisers on the amount of photosynthetic pigments in winter wheat leaves. The research was carried out in the period between 2012 and 2013 at the Experimental Station of Aleksandras Stulginskis University in carbonate shallow gleyic leached soil, (Calc(ar)i-Epihypogleyic Luvisol). The object of investigation: winter wheat cultivars ‘Zentos’ and ‘Ada’. Granular superphosphate (P60) and potassium chloride (K60) fertilisers were spread during sowing, while amonium nitrate (N60) was used in tillering time (BBCH 23–25), after the vegetative growth had resumed. Additionally, the plants were treated with foliar fertiliser urea solution: N30, N40 at booting stage (BBCH 34–36) and N15, N30 at milk ripening stage (BBCH 71–74). After the analysis of the data, it was established that additional fertilization with N30 and N40 fertiliser application rates at later stages of plant development stimulated the accumulation of photosynthetic pigments and prolonged the period of active photosynthesis. Irrespective of treatment with nitrogen fertilisers, genetic properties of the cultivar also had influence on the accumulation of the pigments. Wheat cultivar ‘Zentos’ tended to accumulate larger amounts of pigments. The highest amounts of pigments were found at the beginning of milk ripening stage before additional treatment with N15, N30 fertiliser application rates.

Full textAbstract:
We studied the fiber flax varieties bred in the Tomsk region in 2017–2019 in the subtaiga zone of the Omsk region on the experimental field of the Northern Agriculture Department of the Omsk Agricultural Scientific Center. We provide the material for 7 varieties. The soil of the experimental plot is gray wooded podzolic, medium, loamy with a humus content of 3–4 %. The predecessor is spring wheat after fallow. The research results showed that the weather conditions significantly affected the growth, development, and formation of the yield. In 2017, cold and wet weather generally affected the yield and quality of fiber flax in comparison to 2018-2019. As a result of the research, we established that for 3 years the best varieties were TOST 5 and Tomich. The variety TOST 5 gave a straw yield of 4.70 t/ha with number 1.9, an estimated fiber yield of 1.31 t/ha and a seed yield of 0.80 t/ha with the growth season of 61 days. The variety Tomich was characterized by the high quality of straw with number 2.1 with a short growth season (48 days), it had a straw yield of 4.0t/ha, a fiber yield of 1.18 t/ha and a seed yield of 0.70 t/ha. Therefore, the combination of varieties of different ripening duration will optimize the harvesting timing, raise the flax straw, and get a high yield of quality products.
