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.

Variety Testing

Grain quality of winter bread wheat is an urgent issue in Russia and in the world. The traits and properties of grain that characterize the quality are formed in the field under the effect of weather and climatic conditions. The current study was carried out in 2017–2019. The objects of the study were 12 varieties and 3 promising lines of winter bread wheat of the Competitive Variety Testing. The variety ‘Ermak’ was used as a standard variety. The purpose of the study was to carry out a comparative estimation of grain quality of the varieties and promising lines of winter bread wheat, to identify the variation of traits over the years and to determine the effect of growing conditions on the formation of grain quality. There has been established that the studied varieties and lines formed nature weight from 799 g/l (the variety ‘Aksiniya’) to 830 g/l (‘Yubiley Dona’) and corresponded to the 1-st quality class. There have been identified the varieties ‘Etyud’ (62%; Cv = 6.6%), ‘Ermak’ (62%; Cv = 7.0%) and the line ‘1005/14’ (68%; Cv = 8.1%) with a combination of high values of the general hardness and insignificant variation of the trait over the years. There has been determined that the variety ‘Nakhodka’ (14.11%; Cv = 3.6%) and the line ‘1261/13’ (14.10%; Cv = 6.1%) were characterized by the maximum protein percentage and low values of the coefficient of variation. There has been established that the varieties ‘Aksiniya’ (4.5 points; 7.9%) and ‘Tanais’ (4.0 points; 2.5%) combined a high baking value with the stability of the trait. When estimating the effect of the factors “genotype”, “year of study” and their correlation on the characteristics of grain quality, there has been found that general hardness (52.59%), mass fraction of grain protein (58.31%), dough deformation (57, 78%), valorimetric value (46.01%), volume of bread (41.77%) and general baking assessment (51.24%) were largely dependent on genotype. The growing conditions had an effect on the formation of the quantity and quality of gluten and the P/l ratio.

The current paper has presented the study results on the change of adaptability to water and temperature stresses and the value of productivity according to the stages of variety changing. There have been selected 13 winter bread wheat varieties developed in the FSBSI Agricultural Research Center “Donskoy”. It was found that the varieties of the first stages of the variety changing (I–IV stage, 1950–1989) practically did not differ in the degree of drought tolerance and the value of productivity of winter bread wheat. In this regard, there was carried out an analysis of changes in the adaptability of winter wheat varieties starting from the V stage of the variety changing. The degree of drought tolerance increased from the weakly-medium drought-resistant varieties (37.4–51%) belonging to the V stage of the variety changing to highly drought-resistant samples (80.4–93.3%) belonging to the VII stage of the variety changing. There was a significant productivity increase of the winter bread wheat varieties zoned from 2010 to 2019 (the VII stage of the variety changing). The largest number of stomata per unit of leaf area in the V stage of the variety changing was identified in the variety ‘Don 95’ (12.2 pcs/mm2). In the VI stage of the variety changing, the largest value of this indicator was identified in the variety ‘Don 105’ (18.8 pcs/mm2), and in the variety ‘Krasa Dona’ (26.9 pcs/mm2) in the VII stage of the variety changing. The dry weight of roots of the varieties of the V stage of the variety changing varied from 1.18 (the variety ‘Donshchina’) to 1.41 g (the variety ‘Don 95’), while in varieties of the VI stage this indicator varied from 1.97 (the variety ‘Donskoy Mayak’) to 2.29 g (the variety ‘Don 105’), and the largest dry weight of roots was identified at the VII stage of the variety changing and ranged from 2.34 (the variety ‘Don 107’) to 2.79 (the variety ‘Asket’). The same regularity was established for the change in the amount of roots according to the stages of variety changing.

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.

The current paper has presented the study results on the homeostaticity of the collection samples of soybeans according to the trait “seed weight per plant” in the southern part of the Rostov region, conducted on the fields of the FSBSI “Agricultural Research Center “Donskoy” in 2017-2019. The purpose of the research was to determine the homeostaticity of the collection samples of soybeans according to the trait “seed weight per plant”. The objects of the research were 75 samples of soybeans of the middle early ripening group, which varied according to their morphological, biological and economically valuable traits and properties. There have been selected 27 collection samples of soybeans, which significantly exceeded the standard variety in terms of to the trait “seed weight per plant”. The soybean variety ‘Don 21' developed in the FSBSI “Agricultural Research Center “Donskoy” was used as a standard variety. The meteorological conditions during the growing season of soybeans during the years of study were different, which made it possible to objectively estimate the parameters of homeostaticity. For statistical processing of the results obtained, there were used the Dospekhov's methods of analysis of variance, the homeostaticity indices (Hom) were calculated according to V. V. Khangildin. (1984). According to the study results, it was established that the sample ‘Veselovskaya 5', ‘Line 504/11' and ‘PR 110370 OZ 006' had high productivity indices per a plant, along with high homeostaticity indices. There has been recommended to use them in breeding for homeostaticity and ecological adaptability. The highly productive samples ‘Im 55-2', ‘Kyoto', ‘Kofu', ‘Line 696-1', ‘M-91-212006, ‘RZhT Shuna', ‘SVH 14 TOS 1D' have shown a low index of homeostaticity. They could be characterized as the samples responsive to the improvement of environmental conditions and could be recommended as an initial material when developing varieties of intensive type.
