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.

Purpose and objectives. To evaluate the effect of sorting seeds by size on their quality indicators: germination energy, laboratory germinability and 1000-grain weight. Materials and methods. The experiments were carried out in the experimental field of the Plant Production Institute named after V.Ya. Yuriev of NAAS in accordance with the field experimentation method in 2016–2018; 26 winter bread wheat lines and varieties were studied. The varieties and lines were grown in variety trial experiments; the plot area was 10 m2. Seeds were separated on sieves of a laboratory separator RLU-3; the 1000-grain weight was measured; the laboratory germinability and germination energy were determined. Results and discussion. When winter bread wheat seeds are sorted on sieves, they are separated into fractions with various 1000-grain weights. The separated fractions of winter wheat seeds have different sowing qualities. The 2.5 x 20 mm seeds and 2.8 x 20 mm seeds are of the best quality (germination energy, germinability). It was found that in 2016–2018, the germination energy, laboratory germinability and 1000-gain weight changed depending on the growing conditions. They were the highest in 2017. The varieties with a high 1000-grain weight have been identified: Doskonala, Pryvablyva, Smuhlianka, and Haiok. The highest germination energy and germinability were intrinsic to varieties Yednist, Harmonika and Bunchuk. Yednist (93.3%), Harmonika (94.3%), Metelytsia Kharkivska (94.5%), Bunchuk (94.7%), Alians (93.3%), Podolianka (92.5%), Patriotka (93.6%), Zapashna (93.3%), Dyvo (93.7%), Doskonala (93.6%), Krasa Laniv (94.0%), Smuhlianka (93.1%), and Erythrospermum 408-13 (93.7%) had a high germinability of small seeds (2.2 x 20 mm). To clean these varieties, especially in years with low seed yields, it is recommended to use seeds of the standard size (2.2–2.5 x 20 mm). Conclusions. The relationships between the grain size and sowing qualities of seeds have been established. Separation of seeds is an effective technological method allowing for selection of top-quality seeds

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.

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.

The current paper has presented the results of three years’ study (2012–2014) of the application of various terms and methods of nitrogen additional fertilizing for the winter bread wheat variety “Stanichnaya”. There has been studied efficiency of various terms and methods of nitrogen additional fertilizing with various forecrops. There has been identified an effect of these additional fertilizing on winter bread wheat productivity according to the forecrops. In the control variant, the productivity of the variety according to the forecrop depended greatly on the forecrops: 5.52 t/ha (weedfree fallow), 5.26 t/ha (peas), 4.29 t/ha (maize for grains) and 3.57 t/ha (winter wheat). There has been identified large productivity in the autumn ammonium nitrate fertilizing by the scattering method (in all variants of the forecrops), the productivity raised on 0.38–0.73 t/ha. The study has shown that the economic effect of the ammonium nitrate fertilizing in the autumn was also at maximum profitability, 76–154%, and the conditional net income was 10 675–22 955 rubles/ha. The efficiency of ammonium nitrate fertilizing by the scattering method in the spring on thawed/frozen soil was lower, the productivity increase ranged from 0.21 t/ha sown after peas to 0.65 t/ha sown after maize. Root additional fertilizing with a seeder gave a positive effect only when the variety was sown after for winter wheat and maize, in that case the productivity increase was 0.52 t/ha and 0.46 t/ha, respectively. The conditional net income in these variants exceeded the control variant on 1574–2123 rubles/ha. Carbamide (urea) additional fertilizing was only effective for the variety sown after maize, where the productivity increase was 0.40 t/ha, but profitability (100%) and conditional net income (16 593 rubles/ha) were lower than with ammonium nitrate fertilizing by the scattering method in the spring (112% and 18 080 rubles/ha respectively).
