Aim. To determine the adaptability of modern winter bread wheat varieties by homeostaticity and breeding value of their yields in the northeastern forest-steppe of Ukraine. Results and Discussion. The adaptability of modern winter bread wheat varieties was determined by homeostaticity and breeding value of their yields in the northeastern forest-steppe of Ukraine. It was found that, in mid-tall genotypes, homeostaticity (Hom) ranged 22.6 to 84.5 with a higher breeding value (Sc = 3.49–6.32) compared to semi-dwarf accessions (Hom = 18.9–56, 3 and Sc = 3.16–4.99, respectively). Korovaina (Hom = 84.5) and Vyhadka (Hom = 75.8) (UKR) are highly homeostatic mid-tall accessions. As to the semi-dwarf group, MV Nador (HUN) was the best in terms of this trait (V = 10.8%; Hom = 56.3). We demonstrated that the shares of the middle-homeostatic accessions were 28.6% in the mid-tall group and 30.8% in the semi-dwarf group; the shares of the low-homeostatic accessions were 57.1% and 69.2%, respectively. We selected sources with the highest breeding value for this parameter of adaptability, which exceed its average value in the experiment (Sc = 4.9). They include Metelytsia Kharkivska (Sc = 6.32), Korovaina (Sc = 6.16), Raihorodka (Sc = 6.00), Vyhadka (Sc = 5.74), Zoloto Ukrainy (Sc = 5.63), Darynka Kyivska (Sc = 5.42), and Hubernator (Sc = 5.08) (UKR). The shares of sources distinguished due to their breeding value are 50% in the mid-tall group and 38.5% in the semi-dwarf group. Conclusions. Korovaina (Hom = 84.5; Sc = 6.16) and Vyhadka (Hom = 75.8; Sc = 5.74) (UKR) are the most significant mid-tall genotypes that combine high homeostaticity and breeding value. The sources of adaptability identified in the study of homeostaticity and breeding value are valuable starting material to create new highly adaptive and promising varieties of winter bread wheat in the northeastern forest-steppe of Ukraine.

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.

Winter Bread Wheat

The production of winter wheat varieties, which are characterized by high productivity and sowing qualities of seeds, is one of the ways to improve productivity and gross grain harvest in the region. The current paper has presented data on the productivity, sowing qualities and biological properties of the original seeds of the winter bread wheat varieties ‘Stanichnaya’, ‘Lydia’ and ‘Asket’, grown in the laboratory for primary seed production of the Federal State Budgetary Scientific Institution “ARC “Donskoy”. The purpose of the research was to study the productivity and sowing qualities of the winter bread wheat varieties. Productivity is the main criterion for the value of a variety. It was found that with an average productivity (5.8 t/ha) of the variety ‘Stanichnaya’, the data by the years of 2018–2020 varied from 5.1 to 7.2 t/ha, and for the variety ‘Asket’, at a similar level of average value, the variation ranged from 5.2 to 6.8 t/ha. There was found that 1000-seed weight depended on the variety and climatic conditions, and not only on the cultivation technology. The leader in this indicator was the variety ‘Stanichnaya’, with an average value (44.5g) of 1000-seed weight. The maximum yield of conditioned seeds during the years of research was identified in the varieties ‘Stanichnaya’ (73.5%) and ‘Lydia’ (72.4%); the minimum was in the variety ‘Asket’ (71.7%). There was noted that the germination energy of the varieties ‘Stanichnaya’, ‘Lidiya’ and ‘Asket’ ranged from 88 to 92%. The difference between germination energy and laboratory germination ranged from 5 to 8%. When determining the intensity of the initial growth, it was found that the maximum values of the sprout length and weight of 100 dry sprouts were identified in the variety ‘Stanichnaya’ (11.0 cm and 0.63 g); the smallest values of these traits were identified in the varieties ‘Lydia’ and ‘Asket’. Field germination varied by the varieties from 73 to 82%, deviations of this trait from laboratory germination ranged from 14 to 23%. Over the years of study, for all studied varieties, the sowing qualities of seeds corresponded to GOST R 52325-2005.

The studies were conducted at The V.M. Remeslo Myronivka Institute of Wheat of the NAAS of Ukraine during 2016-17–2018-19 growing seasons. There were estimated 17 winter bread wheat genotypes that were sown in three sowing dates after five preceding crops. Test weight was evaluated according to the State Standard 10840–64. Statistical processing was performed with using programs Statistica 8.0, Excel 2013. It was revealed the significant effect of growing season conditions on grain test weight in winter bread wheat varieties in environments of Ukrainian Forest-Steppe. Significant differences in responses of the genotypes under study on sowing date after different preceding crops were revealed. The most effect of sowing dates on test weight was established in the variety MIP Vidznaka, while the most effect of preceding crops was established in the varieties MIP Yuvileina, Podolianka, MIP Lada, and MIP Darunok. In general, maximal test weight was formed after green manure and the minimal one was after soybeans as preceding crop. The general tendency of decrease in grain test weight with shift in sowing dates from September 26 to October 16 after preceding crops green manure, mustard, sunflower, soybeans was revealed. The sowing date October 05 was optimal for the varieties MIP Valensiia, Estafeta myronivska, MIP Lada after green manure, for the varieties Podolianka, Trudivnytsia myronivska, Hratsiia myronivska, MIP Dniprianka, MIP Lada after mustard, for the varieties Podolianka, Trudivnytsia myronivska, Balada myronivska, Hratsiia myronivska, MIP Assol after sunflower, for the varieties Trudivnytsia myronivska, Estafeta myronivska after maize, for the varieties Podolianka, Trudivnytsia myronivska after soybeans. The varieties MIP Vyshyvanka, Trudivnytsia myronivska, Balada myronivska, Estafeta myronivska, MIP Dniprianka, MIP Vidznaka, and MIP Yuvileina were identified which exceeded significantly the standard variety Podolianka in test weight on average by years of the research, sowing dates, and preceding crops.
