The Relationship

Plant height is an important component of the model of many wheat varieties. Studies aimed at identifying the relationship between important economic characteristics of wheat and heights are relevant given the long process of wheat domestication. The article highlights the results of a research of plant height and lodging resistance of 28 winter wheat varieties created in the period from 1971 to 2017. Studies have shown that varieties vary in height and lodging resistance over the years. In terms of height relative to the variety-standard Perlyna Lisostepu, the highest yield were of the varieties Zhuravka (112 cm), Miryutinka (113 cm), Kievskaya-73 (102 cm), Pamiati Girka (103 cm). The lowest varieties were Gnome (65 cm), Analog (77 cm), Kievskaya polukarlikova (76 cm), Shchedraya Polesia (83 cm). According to the resistance to lodging, the studied varieties can be attributed to different groups. Varieties created after 1992 were resistant to lodging: Kraevid, Polesskaya-90, Gnom, Analog, Kesaria Polisska, Olzhana. Conventionally dividing varieties into groups according to the years of creation in the period from 1971 to 2012, you can notice a tendency to decrease in height and increase resistance to lodging with each subsequent variety change. According to the results of field tests, the average height of winter soft wheat varieties of the Institute of Agriculture created in the period from 1992-2017 decreased by 5 cm compared to varieties created in the period from 1971 to 1992.So, the results obtained indicate the active involvement of short-stemmed genotypes in the breeding process of winter wheat, which are still being successfully studied. Most varieties of the Institute belong to the semi-dwarf group in terms of height and are highly resistant to lodging, and therefore are promising as a source of economically valuable traits.

Winter soft wheat is one of the most important crops. New varieties of wheat should be characterized by a set of valuable economic characteristics, but the most relevant is the creation of varieties with high yields and grain quality, resistant to a complex of diseases and other negative factors. The aim of the study was to evaluate new promising varieties of winter soft wheat breeding of the NSC "Institute of Agriculture NAAS" for grain yield, winter hardiness, disease resistance and grain quality. Experimental studies were conducted at the NSC "Institute of Agriculture NAAS" in 2016-2020, research fields are located in the Fastiv district of Kyiv region. Different weather conditions over the years of research have contributed to a better and more comprehensive assessment of varieties on a set of valuable economic characteristics. During field experiments, the generally accepted technology of growing winter wheat was used. The area of the competitive variety testing site was 20.0 m2, repeated four times. Field, measuring and weighing, laboratory and mathematical and statistical methods were used during the research. In 2018, new varieties of soft winter wheat Krasunia Poliska, Mokosha, Pyriatynka, Fortetsia Poliska, Efektna and in 2020 the variety Zemlerob were transferred to the Ukrainian Institute of Plant Variety Examination for qualification examination. Varieties created in NSC "Institute of Agriculture NAAS" by the method of hybridization using as parent components varieties and lines of local and foreign breeding. The variety Krasunia Poliska, belongs to the Lutescens type, is characterized by high drought resistance, resistance to lodging, germination on stumps, grain shedding. The Mokosha variety, belongs to the Lutescens type, has high drought resistance, is resistant to lodging, germination on stumps and grain shedding. Variety Pyriatynka, belongs to the Lutescens type, has high drought resistance, resistance to lodging, germination on the stump, shedding. Fortetsia Poliska, belongs to the Alborbrum type, is characterized by high drought resistance, resistance to lodging, germination on the stump and shedding of grain. Variety Efektna, belongs to the Erythrospermum type, is short (plant height 64-80 cm), characterized by high drought resistance, resistance to lodging, germination on the stump, shedding. The variety of winter soft wheat Zemlerob, belongs to the Lutescens type, has high drought resistance, resistant to lodging, germination on the stump, shedding of grain. The highest grain yield on average over the years of testing was obtained in the variety Fortetsia Poliska - 7.31 t / ha, varieties Pyriyatynka and Zemlerob with indicators of 7.10 and 7.06 t / ha, respectively, were distinguished by high yields. The yields of Mokosha, Effektna and Krasunia Poliska ranged from 6.27 to 6.95 t / ha. According to the increased winter hardiness, the best varieties are Pyriatynka, Krasunia Poliska, Mokosha and Efektna with a score of 8.0-8.2 points. In the varieties Fortetsia Poliska and Zemlerob the score for winter hardiness was 7.8-7.9 points. Estimation of powdery mildew showed that the maximum percentage of lesions on average over the years of research was found in the variety Mokosha (25.5%). As the most stable selected varieties Efektna, Lisova pisnia, Pyriatynka and Fortetsia Poliska (1.7-11.6%). In terms of resistance to brown rust, all varieties showed high resistance, the damage did not exceed 8.0%. The most stable variety was Efektna (0.3%). The greatest damage to winter wheat varieties was found in leaf septoria, which ranged from 19.0 to 39.3%. The greatest resistance to this disease is determined in the cultivar Zemlerob. New wheat varieties should also be characterized by high levels of protein, gluten and other valuable traits that ensure grain quality. The highest protein content was determined in the grains of the varieties Efektna (11.67%), Mokosha (11.62%) and Krasuni Poliska (11.54%). According to the increased content of gluten, the varieties Krasunia Poliska, Lisova pisnia, Mokosha (19.22-19.66%) were distinguished. According to the highest indicators of sedimentation, the varieties Krasunia Poliska, Pyriatynka and Mokosha (34.50-34.84 %) should be noted, these varieties are also the best in terms of a comprehensive assessment of grain quality. New varieties of soft winter wheat Krasunia Poliska, Mokosha, Pyryatynka, Fortetsia Poliska, Efektna and Zemlerob breedibg of NSC "Institute of Agriculture NAAS" are characterized by high grain yield (up to 7.31 t / ha), increased winter hardiness and disease resistance, as well as good indicators of grain quality: protein content - up to 11.67%; gluten - up to 19.66%. The introduction of these varieties into production will allow to obtain high yields of quality grain.

Abstract Cereal yield loss from eyespot directly depends on the severity of the disease. The aim of this study was to establish the relationship between eyespot damage in winter wheat and components of yield of winter wheat cultivars Ada, Mulan and Tukan in Lithuania in the 2011/2012 cropping season. Several eyespot did not decrease the grain number per ear cv. of Tukan while for cvs. Ada and Mulan the decrease was 14 and 15%, respectively; however, the grain number per ear of moderately eyespot-affected stems of cv. Ada did not differ from that of visually healthy stems. For cv. Ada, the grain weight per ear of moderately affected stems was 5.8% less and that of severely affected stems was 12.8% less than that of healthy stems, while for cv. Mulan the decrease in grain weight per ear was 40.3 and 35.5%, respectively and for cv. Tukan it was 59.0 and 63.2%, respectively for moderately and severely affected stems. The decrease in thousand grain weight of moderately eyespot-affected stems of cv. Ada was less (6.5%) compared with that of cv. Mulan (31.3%) and cv. Tukan (55.8%). Thousand grain weight of severely eyespot-affected stems of cvs. Ada, Mulan and Tukan was 22.2, 26.0, and 65.0%, respectively, less than that of healthy stems. Screening of healthy, moderately and severely affected plants of the winter wheat varieties Ada, Mulan and Tukan for grain number per ear, grain weight per ear and TGW revealed that these varieties differed in tolerance to eyespot

Penza region is characterized by a diversity of natural and climatic zones and considerable variability of meteorological factors over the years. Therefore, the creation of high-yielding winter soft wheat varieties with high protein content in grain is one of the most significant challenges in this crop breeding. The purposes of this research are twofold: assess the ability of winter wheat varieties to form high-protein grain in various environmental conditions and isolate a valuable source material for breeding. The research objective is to evaluate winter wheat varieties by such indicator as “mass fraction of protein in grain”. The research was carried out from 2008 to 2017 in a forest-steppe zone of the Penza region. The soils of the experimental field – medium-humus medium-thick leached chernozem with the 35–40 cm depth of the plowing horizon. Ninety varieties of winter wheat from the world collection were the material for the research. The forecrop is black fallow. Square of experimental fields is 3 m2, triple replication. Seeding rate – 5.5 million germinating grains/ha. Standard – winter soft wheat variety ‘Fotinya’. Mass fraction of protein in grain in early ripening and mid-early varieties of winter wheat significantly differed from those of the mid-maturing group. Winter wheat varieties from the mid-ripening group were distinguished by a high protein content (on average 15.5 %), high yield (on average 3.8 t/ha), high yield of protein per hectare (on average 0.59 t/ha). According to the level of stress resistance, varieties ‘Fotinya’ and ‘Moskovskaya 39’ stood out (0.7 and 0.6, respectively). The following varieties are characterized by high genetic flexibility (15.3–16.2): ‘Fotinya’ (Penza region), ‘Moskovskaya 39’ (Moscow region), ‘Bezenchukskaya 380’ (Samara region), ‘Badulinka’ (Volgograd region), ‘Ershovskaya 25’ (Saratov region), ‘Zimorodok’, ‘Pobeda 50’ (Krasnodar Territory), ‘Zernogradka 8’, ‘Konkurent’ (Rostov Region). All the aforementioned varieties have less variability of a characteristic over the years (coefficient of variation – 3.2–9.7 %) and are recommended for use as a starting material for creating new forms.

The purpose of our investigation was to identify the features of the depressive effects of the aftereffect of different doses of gamma-rays on winter wheat varieties of local breeding in terms of germination, survival, morphometry, yield. The parameters of germination and survival, the passage of the main phases of ontogenesis in winter wheat plants of French varieties (Courtiot and Gallixe) at the first generation were studied. The influence of mutagenic depression on parameters of yield structure (morphometry of mature plants) was established and the level of their variability was estimated too. In 2019 - 2020, experiments were conducted in the research fields of the research center of the Dnieper State Agrarian and Economic University. The experiments used seeds of Courtiot and Gallixe varieties, irradiated with gamma rays in doses of 100, 150, 200, 250, 300 Gy. Control was dry seeds. The variety Gallixe can be classified as resistant to gamma-rays, the variety Courtiotwas corresponded to high-sensitive. Parameter of germination and survival were directly correlated with increasing dose, with a dose of 200 Gy already semi-lethal, a dose of 250 Gy for variety Courtiot was sublethal, 300 Gy doze full-lethal, for the variety Gallixe sublethal was 300 Gy dose by which almost no plant material was obtained. Such parameters as plant height, weight of grain from the main spike and weight of thousand grains, partially (except for doses of 100-150 Gy) weight of grain from the plant reliably reproduce the mutagenic depression. Depression of the variety is affected by the dose of mutagen more than the genotype of the variety; the plant height parameter clearly demonstrates mutagenic depression. According to the results of factor and discriminant analysis as indicators affected by genotype-mutagenic interaction should be used germination and survival, pollen sterility, plant height, grain weight per spike, weight of thousand grains. Doses of 100 - 200 Gy are optimal for further use to obtain mutations; it is possible to use a dose of 250 Gy for the variety Gallixe.

Abstract The article discusses the impact of severe drought on the growth and development of winter wheat plants. The studies were carried out in 2018-2020. As a starting material, we used 57 samples of winter soft wheat bred by ARC “Donskoy”. The studies were carried out under laboratory and vegetation methods. According to the analysis, it was revealed that the highest values of the index of complex resistance were shown by the samples: intensive type - 1630/17 (282.8 rel.units), 2078/16 (265.1 rel.units), 1990/17 (265, 0 rel.units); semi-intensive type -1727/17 (260.6 rel. units), 2243/17 (258.6 rel. units), 522/16 (252.8 rel. units). The maximum value of the degree of drought resistance of samples of the intensive type was noted for lines 2243/17 (92.4%), 1727/17 (84.9%), and 522/16 (82.6%). Among 36 samples of winter soft wheat of intensive type, high drought resistance was noted in 67% (24 samples) with germination from 71.6 (Univer) to 92.9% (1630/17). High values of heat resistance (I-81-100% of germination) out of 57 studied samples of winter wheat were noted in 56 genotypes, the indicators of which ranged from 85.1% (1181/16) to 98% (Zodiac, 1166/15, 1275/16). The highest grain yield under model drought conditions was noted for winter wheat varieties Zodiac (332.86 g/m2), Premiera (332.48 g/m2) and Podarok Krymu (317.50 g/m2), which is higher than the yield of the Ascet classifier (292.97 g/m2) by 8.0-13.7%..

The knowledge of climate change effects on variations of winter wheat yields are crucial for productions. Our objectives were to investigate the relationship between yield-related indices of winter wheat and the related climatic variables (selected using variance inflation factors) at the 20 sites of Xinjiang, China over 1981–2017. The background of climate and yield changes was analyzed from temporal and spatial respects. The number of independent climatic variables was selected with the variance inflation factor method to remove the multicollinear feature. The Pearson correlation was conducted between the first difference values of climatic variables and yield-related indices of winter wheat (namely plant height, growth period duration, 1000-kernel weight, kernel number per ear, biomass and yield) to find the key climatic variables that impacted winter wheat growth and yields. The multi-variate linear and nonlinear functions were established step by step using the selected key climatic variables. The best function was determined for each site (significant for p < 0.05). From the results, there were general wetter and warmer trends of the climatic variables. Correspondingly, shortened winter wheat phenology and increased growth and yields were observed for most sites. Still, the climatic trends had mixed effects on winter wheat yields. The effects of precipitation, mean air temperature and relative humidity on plant height and growth period duration agreed well. Different sites had different major climatic drivers for winter wheat growth or yields, and the best functions of growth and yields could be linearly or nonlinearly, mostly described by multi-variate functions. The winter wheat growth or yield indices were also found to be closely connected with the soil water content status at the eight sites. The relationship between winter wheat growth or yield and climate provided useful references for forecasting crop production and for projecting the impact of future climate changes.

Improving the quality of wheat grain is an important task of agricultural production. In recent years, the production of strong and valuable wheat, necessary for the production of high-quality baking flour, has decreased. In this regard, the study of the quality of grain varieties of winter wheat in specific soil and climatic conditions of the Rostov region is becoming topical. Therefore, the purpose of our research was to study the main indicators of grain quality of varieties of soft winter wheat (protein and gluten content, flour strength, bread size from 100 g of flour) in ecological variety trials to select the best under conditions of the Rostov region. The studies were carried out on the trial fields of the Laboratory of selection and seed production of winter soft wheat of intensive type of the State Scientific Establishment “Agricultural research center «Donskoy»” (Rostov region) in 2014–2016. Seventy-five varieties were studied in the course of the research. Planting dates – optimal for implementation of agricultural and agro-technical measures. Planter – «Wintersteiger Plotseed S.» Seed placement depth – 4–6 cm. Preceding crop – black fallow. Accounting square of fields – 10 m2, double replication. Seeding rate – 4.5 million seeds per hectare. Grain quality was assessed according to the methods of the national standards of the Russian Federation. Such grain quality indicators as gluten content (according to GOST R 54478-2011), protein mass fraction (as required by GOST 108460-91), baking properties of flour (in a laboratory using the remix method) were determined. The article discusses the main indicators of the quality of grain and flour of winter soft wheat varieties in ecological variety testing and compares them. Analysis of the main indicators of the quality of varieties in trials showed that in the south of the Rostov region in 2014–2016 flour strength and gluten content were the most variable indicators. In terms of protein content (> 14.5 %), 8.0 % of the studied varieties were in full compliance with strong wheat standards; by the gluten content (> 28 %) – 7.0 %; by the flour strength (>280 e.a.) – 9.0 %. Five varieties of winter soft wheat: ‘Aksinya’, ‘Tanais’, ‘Asket’, ‘Nakhodka’, ‘Yumpa’ (Russia) with a complex of economically valuable traits are of greater interest for practical breeding in terms of improving grain quality.

In the conditions of the Kirov region, 375 samples of soft spring wheat of various ecological and geographical origin (from 30 countries) of the Federal Research Centre N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) collection were studied. The assessment of the source material by yield, duration of the growing season, plant height, lodging resistance, productivity of the ear and plant, 1000-grain mass is presented in the form of a 9-point system of the severity of the trait for three years of field study. As sources for breeding, varieties that combine high yield (5.0...9.0 points) with a high level of economically valuable traits (7.0...9.0 points) were identified. The maximum average point (9.0) for yield capacity was noted by the variety Karabalykskaya 91 (Kazakhstan). The optimal height (53.9...74.0 cm) and lodging resistance were noted in the varieties: Estivum 155 (Russia), Kvorum (Ukraine), Epos, Ethos, Nandu, Schenk and KVS Akvilon (Germany), AC Phil and PT-741 (Canada), Hybrid (Mexico), Leguan (Czech), PS-133 (China) and SSL 25-2 (USA). Early maturation was distinguished in the domestic varieties Skala and Iren (80...87 days). The samples Line 3691h, Izida, FPCh-Ppd-m, Gerakl, Sibirskaya 16 (Russia), Kvorum (Ukraine), Attis and Nandu (Germany), Musket (England) were distinguished by the length (7.3...8.8 cm) and the number of grain of the main ear (32.1...39.9 pcs.). The varieties Voronezhskaya 16, Gerakl, Saratovskaya 72, Saratovskaya 73, Sibirskaya 16, Serebristaya, FPCh-Ppd-m and Ekada 6 (Russia), Anshlag and Kvorum (Ukraine), AC Gabrieland Hoffman (Canada), Attis and Nandu (Germany) were distinguished by a high grain weight per ear (1.28...1.58 g). The varieties Zakamskaya (Russia), Rassvet (Belarus), AC Cadillac (Canada) and PS-95 (China) are recommended as sources of high protein content. It is shown that the wheat yield in the region is closely related to the plant height (r = 0.67), the ear and plant productivity elements (r = 0.24...0.41), the protein content (r = -0.49) and does not depend on the 1000-grain mass (r = 0.04). Sixteen samples were identified with complex resistance to dominating fungal diseases. Samples Altajskaya 110, Kinelskaya 61, Line 2, Lutescens 30 and Estivum V313 (Russia) combined high yield with aluminum resistance. Varieties Altajskaya 100, Baganskaya 95, Line 3691h, Novosibirskaya 20 and Estivum 155 (Russia), Klein Vencedor (Argentina) and NOS Norko (Germany) were characterized by high yield and drought resistance. Based on the obtained results, a bank of sources of economically valuable traits was created, which allows to involve genotypes adapted to the conditions of the region in the breeding process.

Winter Wheat Varieties

To successfully increase grain production and improve its quality, the development and introduction of new winter wheat varieties is of great importance. The winter soft wheat varieties developed by the FSBSI “Agricultural Research Center “Donskoy” and included into the State List of Breeding Achievements of the Russian Federation are able to form grain with 30.0% gluten and more, and are suitable for the first, second and third class of baking. A comparative characteristic of the grain quality of winter wheat varieties of the intensive type included in the State List and their ability to form food grain suitable for baking is currently of practical interest. There have been studied 6 varieties in the conditions of drought in 2013 and 2014 (the amount of precipitation during the growing season was 190.0–191.5 mm, the average daily air temperature was 20.3–20.9 °C), and in the conditions of excess moisture in 2016, 2017 (the amount of precipitation was 274.2–292.8 mm, the average daily air temperature was 19.5–20.4 °C). The studied varieties formed the highest productivity from 8.70 to 9.01 t/ha under conditions of excessive moisture. Under drought conditions, productivity of the varieties decreased significantly and ranged from 6.50 to 7.69 t/ha. Better grain quality of the studied varieties was formed in the conditions of the drought of 2013, 2014 with 14.9 to 15.9% of protein and 27.9 to 31.0% of gluten. Food grain close to the first class (from 30.0 to 31.0% of gluten) were formed by the varieties “Aksiniya”, “Tanais” and “Nakhodka”; the second class (more than 28.0% of gluten) was obtained from the varieties “Shef” and “Etuyd”. The ranking method according to grain quality indicators allowed establishing an average rank and identifying the varieties “Aksiniya”, “Tanais”, “Nakhodka” and “Shef” with the best baking traits.
