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.

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 current paper has presented the study results of SDS-sedimentation and grain quality indicators of the winter bread wheat varieties in an interstation variety testing from the research institutions of the Russian Federation, Ukraine and France. The research work was carried out in 2017–2019 in the field of the laboratory for breeding winter bread wheat, the forecrop was maize for grain. The purpose of the research was to estimate SDS-sedimentation, protein percentage in grain, quantity and quality of gluten in the winter bread wheat varieties of interstation variety testing, for the subsequent introduction of the best samples in the breeding process aimed at improving grain quality. Grain quality indicators of the winter bread wheat varieties were identified in the laboratory for biochemical estimation of breeding material and grain quality using IR spectroscopy on ‘SpektraStar 2200’ analyzer. There was established that according to the SDS-sedimentation most of the samples corresponded to strong wheat (50–63 ml). There have been identified the genotypes with the highest values of this trait, such as ‘Shef’ (58 ml), ‘Nakhodka’ (59 ml) and ‘Don 107’ (61 ml). The largest gluten content in grain was identified in the varieties ‘Don 107’, ‘Shef’, ‘Kavalerka’, ‘Timiryazevka 150’ and ‘Nakhodka’ (25.5–26.2%). The largest protein percentage in grain has been identified in the varieties ‘Don 107’, ‘Shef’, ‘Aksinya’, ‘Nakhodka’ and ‘Timiryazevka 150’ (12.5-12.8%). The varieties ‘Don 107’, ‘Shef’, ‘Nakhodka’ and ‘Timiryazevka 150’ were identified according to the studied traits and were recommended to be involved in the breeding process as parental forms.

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.
