The study aimed to identifying peculiarities of formation and variability of grain test weight in winter bread wheat genotypes depending on the growing season conditions, sowing dates and different preceding crops. 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.

In the ecological conditions of the central part of the Ukrainian Forest-Steppe (The V. M. Remeslo Myronivka Institute of Wheat, NAAS of Ukraine) the influence of growing season conditions (2016-17–2018-19), sowing dates (September 26, October 5, October 16) and different preceding crops (green manure, mustard, soybean, sunflower, corn) on variability of 1000 kernel weight of seventeen modern genotypes of winter wheat was investigated. Under environments of the central part of the Ukrainian Forest-Steppe, significant variability in the trait depending on the factors under study was revealed. Part of sum square for the growing season conditions in the variation of 1000 kernel weight of winter wheat was the most (63.2%). Part of sum square for genotype was 7.0%, for preceding crop it was 4.8%, for sowing dates it was 0.4%. In terms of growing season, the variation in part of sum square was 23.5–30.1% for genotype, 12.7–39.8% for preceding crop, 0.8–6.1% for sowing date, and 2.0–26.5% for interactions between them. During the period of the study, on average for all genotypes, the maximum 1000 kernel weight was obtained after green manure (42.6 g), the least one was after soybean (39.0 g). When changing the sowing dates from September 26 to October 16, it was revealed a general tendency of decrease 1000 kernel weight after the preceding crops mustard, sunflower, corn, and soybean. Significant differences in the response of genotypes under study on the sowing dates after different preceding crops were revealed. The most influence on 1000 kernel weight was established for preceding crops in the variety MIP Darunok and for sowing dates in the variety MIP Vidznaka. There were distinguished the varieties Trudivnytsia myronivska, Balada myronivska, MIP Dniprianka, Avrora myronivska, MIP Darunok which significantly exceeded the standard by 1000 kernel weight on average through the growing season conditions, sowing dates, and preceding crops.

Purpose. Reveal the features of the formation of a quali­ty indicator complex in winter bread wheat depending on the growing seasons, preceding crops and sowing dates, as well as differentiate and identify genotypes with high and stable levels of manifestation. Methods. Field, laboratory, statistical. Results. A different share of the influence of the year conditions, the preceding crop, the sowing date and their interactions on the quality indicators of some varie­ties was determined. A different reaction of varieties in terms of quality indicators, depending on the investigated factors was revealed. The variation was very low for test weight, water absorption ability of flour, crumb porosity. Strong variation was observed for flour strength after sunflower and soybean as preceding crops, alveograph configuration ratio after sunflower and soybean, index of elasticity dough after corn, valorimetric value after mustard, dough dilution degree after green manure, sunflower, corn and especially after mustard and soybeans. The varieties, which on average for 2016/17–2018/19 reliably exceeded the standard both in individual indicators and in general in terms of physical indicators of grain and flour quality and dough rheological properties. GYT biplot analysis identified the genotypes ‘MIP Vidznaka’ and ‘MIP Assol’ with a more optimal combination of increased yield and a complex of quality indicators in terms of different years, preceding crops and sowing dates. Some varieties, namely, ‘Estafeta myronivs’ka’, ‘Trudiv­nytsia myronivs’ka’, ‘MIP Valensiia’, ‘MIP Yuvileina’, ‘Balada myronivs’ka’, ‘Vezha myronivs’ka’ were inferior to them, but were significantly superior the others. Conclusions. The selected by quality indicators varieties as genetic sources can be used in breeding process. A more stable level of yield and quality indicators at different sowing dates after different preceding crops should be expected for growing varieties ‘MIP Vidznaka’, ‘MIP Assol’, as well as ‘Estafeta myronivs’ka’, ‘Trudivnytsia myronivs’ka’, ‘MIP Valensiia’, ‘MIP Yuvileina’, ‘Balada myronivs’ka’, ‘Vezha myronivs’ka’. The peculiarities obtained in the research should be taken into account when evaluating and differentiating genotypes in breeding process, as well as developing basic elements of technology for growing the varieties of winter bread wheat.

It was found that varieties Novosibirskaya 31 and Iren have an advantage in yield and grain quality over Omskaya 36 and Tyumenskaya 25 in terms of the predecessors of annual grasses and green manure fallow. For varieties Omskaya 36, Tyumenskaya 25, Iren, the background of mineral nutrition is optimal for obtaining a yield of 4 t/ha. A further increase in yield leads to a decrease in grain quality. The exception was the Novosibirskaya 31 variety, which retained the grain quality to a yield level close to 5 t/ha. The best sowing dates are the first and second.

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.
