The current paper has presented the characteristics of the new winter bread wheat varieties of unified type developed by the FSBSI Agricultural Research Center “Donskoy”. Winter wheat is the most valuable grain food crop grown in vast areas. Breeding plays an important role in increasing production volume and improving grain quality as the basis of the country’s food fund. Expanding grain crops area, among which wheat predominates, there is a problem of crop rotation. Therefore, the development of unified varieties capable of producing stable high grain yields after various forecrops is one of the most urgent areas of breeding work for winter bread wheat. The purpose of the current study was to characterize the new winter bread wheat varieties of unified type developed by the FSBSI Agricultural Research Center “Donskoy” according to the main economically valuable traits. Due to the intensive breeding work over the past decade, on the basis of some of the best zoned varieties ‘Ermak’, ‘Stanichnaya’, ‘Donskoy syurpriz’ there was developed a number of new promising genotypes, which are already being used in production sowings of winter wheat in the Rostov region and other regions of our country. The new winter bread wheat varieties of unified type ‘Lydia’, ‘Kapitan’, ‘Lilit’, ‘Krasa Dona’, ‘Volnitsa’, ‘Volny Don’, ‘Zhavoronok’ and ‘Polina’ are more productive than their parental forms. In combination with grain of high quality, resistance to bio and abiotic environmental factors, they are very valuable, beneficial for cultivation and improvement of the production of commercial wheat grain of high quality.

Variety Testing

The breeding work with the winter bread wheat in the Federal State Budgetary Scientific Institution “Agricultural Research Center “Donskoy” is being carried out taking into account the increasing aridity of the local climate, the availability of different soil and climatic zones, various forecrops. Every year in the Rostov region there is an increase in the sown area under winter wheat. So, in 2020 the grain crop was sown on more than 2.6 million hectares. Most of it is sown after such non-fallow forecrops as peas, maize, sunflower and other crops. In this regard, it is important to develop and introduce into production winter bread wheat varieties based according to these forecrops. The laboratory for breeding and seed production of winter bread wheat of half-intensive type was established in 1978. For the period from 1978 to 2019, 36 varieties were developed in the laboratory and sent to the State Variety Testing. The main task of the crop breeding for non-fallow forecrops was and still remains to develop highly productive varieties with high frost resistance, drought resistance, heat resistance, resistance to major diseases and grain quality of strong and valuable wheat. In 2020 22 winter bread wheat varieties, developed in the laboratory, have been included into the State List of Breeding Achievements of the Russian Federation. Currently five winter bread wheat varieties ‘Polina’, ‘Ambar’, ‘Niva Dona’, ‘Podarok Krymu’ and ‘Premiera’ are undergoing the State Variety Testing. There is still going on the work on the development of new winter bread wheat varieties that meet modern production requirements, with a wide ecological adaptability and stability of productivity and quality of grain and flour.

Winter Bread Wheat

The systematic study on winter wheat breeding began in 1955 in the former Zernograd experimental station, and now the Federal State Budgetary Scientific Institution “ARC “Donskoy”. Under these conditions, the development of the most suitable for local conditions varieties of intensive type with increased frost resistance determined the main direction of winter wheat breeding in those years. In the early 1980s, the area of black fallow increased in the Rostov region, much attention was paid to irrigated agriculture. There was planned to increase the area under irrigation in the North Caucasus to 1 million hectares. Therefore, there was set a goal to develop highly productive, low-stemmed, resistant to lodging varieties, responsive to mineral fertilizing with complex immunity to diseases. The breeding work of the laboratory for the breeding and seed production of winter bread wheat of an intensive type over the past forty years resulted in the development of 22 varieties of intensive type with good adaptability to the conditions of the Rostov region. In 2020, 17 winter bread wheat varieties of an intensive type were included into the State List of Breeding Achievements, five varieties ‘Yubiley Dona’, ‘Zodiak’, ‘Univer’, ‘Razdolye’, ‘Rubin Dona’ are currently undergoing the State Variety Testing at the SVTs of the Russian Federation. A stable productivity improvement is possible only with the emphasis on the development of varieties with broad adaptive properties, providing sufficiently high yields under various cultivation conditions. Among the breeding traits that affect productivity stability, the most significant in the conditions of the Don are winter and frost resistance, disease resistance, drought resistance, early ripeness, and grain quality. Therefore, the adaptive potential increase is the most important task for the future breeding. In order to solve this problem, intraspecific and interspecific hybridization, followed by targeted selection, remains the main breeding method of winter bread wheat of an intensive type.

Resistant Varieties

Systematic work on the development of winter wheat varieties possessing resistance to a complex of the most harmful diseases has been carried out in the Agricultural Research Center “Donskoy” since the early 1970s. During this period, there has been created a large number of varieties that possess resistance to 3–4 diseases in conditions of infectious backgrounds of pathogens. Due to the analysis of varieties, there was identified a small number of varieties resistant to powdery mildew. Powdery mildew, caused by the fungus Blumeria graminis (DC) Speer, annually occurs on wheat, affecting all aboveground plant organs. Earlier the FSBSI “ARC “Donskoy” developed and widely cultivated the medium-resistant varieties ‘Tanais’ (2006), ‘Nakhodka’ (2015), ‘Etyud’, ‘Shef’, ‘Lilit’ (2016), ‘Volnitsa’ (2017), ‘Polina’, Yubiley Dona’ , ‘Podarok Krymu’ (2018), ‘Niva Dona’ (2019). In recent years, breeders have developed such varieties with high resistance to the pathogen as ‘Donskaya Step’ (2016), ‘Premiera’, ‘Univer’ (2018), ‘Priazovye’, ‘Zolotoy Kolos’ (2020). But the breeding process of varieties for resistance to powdery mildew is difficult, since it is explained by the small number of effective resistance genes and their sources. Therefore, the purpose of the current study was to identify new sources of resistance to the pathogen. Under the conditions of artificial infection, during last 10 years there was conducted a testing of 302 varieties and samples of winter wheat of domestic and foreign breeding. There have not been identified immune varieties. There was identified a small percentage (15.2) of varieties that were resistant to the pathogen. Among the Russian varieties they were ‘L 3191 k-5-8’, ‘Akhmat’, ‘Alievich’, ‘Barier’, ‘Ulyasha’, ‘Knyaginya Olga’, which were not attacked by the disease over the years of testing. Among foreign varieties, the varieties ‘Bombus’, ‘Sailor’ (France), ‘Etana’, ‘Rotax’, ‘KVS-Emil’ (Germany), ‘Fidelius’ (Austria), ‘MV 09-04’ (Hungary) were identified as the best ones in their resistance to powdery mildew. All identified sources of resistance have been recommended in breeding programs for immunity.

Bread Wheat Variety

Breeding success is determined by the correct choice of agro-ecotype. In this regard, we have carried out a comprehensive estimation of 75 winter bread wheat varieties and samples of the competitive trials. The variety ‘Ermak’ was used as a standard. The study was carried out using the material and technical base of the Federal State Budgetary Scientific Institution Agricultural Research Center “Donskoy” (FSBSI “ARC “Donskoy”) in 2017–2019. The purpose was to study the correlation among economically valuable traits of winter bread wheat varieties and samples and to find genotypes similar in their parameters to the model variety based on curvilinear regressions. As a result of the phenotypic estimation of the quantitative traits of winter bread wheat varieties and samples, there was determined an average level and their variability degree. Their productivity ranged from 8.52 to 10.51 t/ha. Through the years of study, the variation coefficients indicated a high stability of these features (from 0.9 to 10.0%). In order to identify the similarities and differences between varieties and samples, there has been conducted a cluster analysis. As a result of this analysis, there has been selected the winter bread wheat variety ‘Yubiley Dona’ (C25), parameters which were more identical to the model (C76). This variety is recommended for further breeding process to improve the studied basic economic traits.

Study Results

The current paper has presented the results of a five-year (2016–2020) study of nine winter bread wheat varieties (‘Aksinya’, ‘Nakhodka’, ‘Etyud’, ‘Shef’, ‘Donskaya Step’, ‘Yubiley Dona’, ‘Univer’, ‘Zodiak’, ‘Ermak’ – standard) developed in the SSE “Agricultural Research Center «Donskoy»” (city of Zernograd). In the competitive variety testing, they were scrutinized according to productivity, its elements, ecological stability, adaptability and breeding value. The purpose was to study the new winter bread wheat varieties of intensive type developed by the ARC “Donskoy” on productivity, adaptability and their indicators, as well as a balance between them, in order to identify new promising genotypes. According to the study results, it has been found that the average productivity was 9.32 t/ha in 2016–2020. The highest productivity was identified in the varieties ‘Univer’ (9.86 t/ha) and ‘Donskaya Step’ (9.76 t/ha). Structural analysis of the studied varieties has shown that their productivity was formed due to such elements as ‘productive plant density’ (variety ‘Shef’); ‘productive tilling capacity’ (variety ‘Etyud’); ‘number of spikelets per head’ (variety ‘Univer’); ‘number of kernels per head’ (variety ‘Ermak’); ‘1000-grain weight’ (variety ‘Zodiak’). While studying the varieties according to general adaptive capacity, such varieties as ‘Zodiak’ (0.10), ‘Donskaya Step’ (0.44) and ‘Univer’ (0.54) have been identified. Varieties ‘Yubiley Dona’ (1.07), ‘Donskaya Step’ (1.06), ‘Univer’ (1.05) and standard variety ‘Ermak’ (1.02) were found highly adaptable to environmental conditions, i.e. these varieties positively respond to the improvement of growing conditions and belong to the varieties of intensive type. Variety ‘Etyud’ (0.03) has demonstrated the maximum stability over the years of study, ‘Univer’ (0.60) and ‘Ermak’ (0.17) turned to be less stable. In our trials, all varieties had a breeding value almost at the same level, ranging from 5.10 (‘Ermak’) to 5.96 (‘Donskaya Step’). Taking into account the complex of such indicators as general adaptive capacity, stability and breeding value, varieties ‘Donskaya Step’ and ‘Univer’ can be referred to as the most adaptive ones among all studied in the current work.

The purpose of the current study was to estimate variability of the values of indicators that characterize physical and rheological dough properties, to identify the correlation between them, and to isolate genetic sources. The objects of study were 20 winter bread wheat varieties. Field trials were carried out in 2017–2019 in the fields of the department of winter wheat breeding and seed production, the forecrop was maize for grain. The variety ‘Don 107’ was used as a standard. The quality of grain and flour of the winter bread wheat varieties was assessed in the laboratory for biochemical estimation of breeding material and seed quality. There have been identified the varieties ‘Asket’ (26.9%), ‘Podarok Krymu’ (26.2%), ‘Zolotoy Kolos’ (25.5%) and ‘Izyuminka’ (25.5%) with the maximum gluten content in grain. It was determined that the trait ‘gluten deformation index’ varied from 62 u.v. to 77 u.v., all varieties corresponded to the 1st quality class. There have been identified the genotypes ‘Volny Don’, ‘Don 93’, ‘Premiera’, ‘Podarok Krymu’, ‘Ambar’, ‘Donskoy Surpriz’ and ‘Izyuminka’ with low values of the variation coefficient of the trait. There have been identified the varieties ‘Krasa Dona’ (6.7%), ‘Zhavoronok’ (6.8%) and ‘Asket’ (8.2%) with low values of the variation coefficient of the trait ‘specific work of dough deformation’. There have been identified the varieties ‘Don 93’, ‘Izyuminka’ and ‘Podarok Krymu’, which according to P/L corresponded to the class of strong wheat. It was found that the varieties ‘Zolotoy Kolos’ and ‘Volnitsa’ corresponded to the class of strong wheat according to the valorimetric assessment. Correlation analysis showed that the rheological dough properties were significantly influenced by gluten content in grain. There has been estimated the quantitative manifestation and variability of the traits, which characterize the rheological and physical dough properties. There have been identified the varieties with the smallest varietal variation of traits, which are recommended to use in the breeding process as sources of useful traits and properties. The selection according to the traits ‘delute of dough’ and ‘valorimetric assessment’ allow developing and introducing into production genotypes with good baking properties.

The current paper has presented the study results on estimating the effect of the upper leaves’ area of winter bread wheat samples on productivity and its elements. There have been tested nine winter bread wheat varieties of intensive type developed in the FSBSI “Agricultural Research Center “Donskoy”. The current study has identified that the largest upper leaves’ area under insufficient moisture supply during the periods of head formation and flowering was produced by the variety “Etyud” (31 cm2 in a heading period; 29.4 cm2 in a flowering period). During the period of milky kernel ripening, the variety “Shef” has also shown the largest upper leaves’ area under insufficient moisture supply (17.7 cm2). The variety “Yubiley Dona” has shown a minimal decrease in the upper leaves area to milky kernel ripeness (40%). The evaluation results of productivity and its structure have shown that the largest value of the number of productive stems per 1 m2 in arid conditions was identified in the varieties “Etyud” (261 pcs.) and “Shef” (254 pcs.). According to the number of kernels per main head, the variety “Donskaya Step” was the best with 32 pcs. Large kernel weight per main head was identified in the varieties “Donskaya Step” (0.72 g), “Shef” and “Etyud” (0.67 g), and according to 1000 kernel weight the varieties “Etyud” (25.9 g) and “Zodiak” (25.2 g) were the best ones. The varieties “Etyud” (163.7 g/m2) and “Shef” (168.6 g/m2) have produced the maximum yields, that means the best functioning of all productive systems of winter bread wheat. The estimation of the samples according to the correlation between photosynthesis efficiency of the upper leaves’ area and kernel percentage (ZFL) has identified the samples “Donskaya Step”, “1005/14”, “Univer”. According to the correlation between photosynthesis efficiency of the upper leaves’ area and kernel weight per head (MFFL) the variety “Donskaya Step” showed the best results. The conducted study ad obtained results made it possible to identify the varieties “Shef”, “Etyud” and “Donskaya Step”.

Abstract The aim of the research was to evaluate the relative and absolute protein content in winter wheat grains, to determine the samples that have the maximum values of the studied traits, and to use the selected genotypes in breeding programs. The trials of the winter bread wheat varieties, sown after maize for grain were carried out in 2018-2020. The objects of the study were 13 winter bread wheat varieties (Triticum aestivum L.) developed in the Agricultural Research Center “Donskoy”. The current research established that when selecting parental varieties for crossing to improve grain quality of winter bread wheat varieties, there should be chosen the forms with the highest relative and absolute protein percentage in grain. These genotypes include Don 107, Ermak and Lidiya, whose relative protein percentage in grain was 12.96%, 13.01% and 13.06% respectively. The varieties Don 107, Ermak, Lidiya, Volnitsa and Zhavoronok were characterized by the maximum absolute protein percentage in grain with 5.43 g, 5.62 g, 5.57 g, 5.56 g and 5.54 g respectively. The 1000 grain weight of these varieties averaged 42.1 g (Don 107), 43.6 g (Ermak), 43.1 g (Lidiya), 43.5 g (Volnitsa) and 44.5 g (Zhavoronok).
