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.

Purpose. Develop a simplified method for estimating the color of flour and pasta using Adobe Photo Shop® software. Methods. The research material was grain of varieties and selection lines of wheat species Triticum durum, T. dicoccum, T. timopheevii bred in the Рlant Production Institute nd. a. V. Ya. Yuryev and samples of the National Center for Genetic Resources of Plants of Ukraine, 2018–2020 harvest. Batch of flour and pieces of dough were scanned using EPSON Scanner 010 F. Color was evaluated using Adobe PhotoShop®. The level of carotenoids was determined by spectrophotometric method. Results. Visual assessments of flour and pasta color, presented by different researchers, differ significantly (up to 2–3 points on a 9-point scale). At the same time, the use of the developed method of express color evaluation of flour and pasta samples in Adobe PhotoShop® with the color evaluation system L*a*b*, used in modern reflectometers, allows to obtain data in numerical value and provides high accuracy. In the case of the developed me­thod, correlations were established between the content of carotenoids and the index b* of flour (r = 0.41 / ≤ 0.05) and pasta (r = 0.60 / p ≤ 0.001) and allowed to select the best in flour color selection lines 10-56, 10-65, 14-153, sample T. durum var. falcatomelanopus, in pasta color – lines 10-56, 10-65, 11-29, 12-3. Conclusions. The developed method provides high accuracy and can be used to evaluate the color of pasta and wheat flour, simplifies the evaluation of test samples, standardizes the parameters of agricultural products and avoids subjective judgment. The established weak correlation between the carotenoid content and the b* value of flour indicates the effect on the color of flour not only orange but also yellow and red pigments, and the ave­rage correlation between the carotenoid content and the b* value of pasta indicates the influence of the products of polyphenols oxidation reactions of wheat grain. The best in color flour and pasta lines were selected for breeding work to increase the content of carotenoid pigments in grain.

Для оцінки стійкості до фузаріозу колоса в 2009 році 41 сорт твердої та м’якої пшениці, переважно з Італії, пройшов сортовипробування у CIMMYT (Міжнародний центр поліпшення кукурудзи та пшениці). Крім того, виконано оцінку впливу одного з основ­них QTL стійкості до фузаріозу колоса (Qfhs.ndsu-3BS QTL), вперше виявленого у китайського сорту пшениці м’якої ‘Sumai 3’, на хромосомі 3В, у 125 удосконалених ліній пшениці твердої BC4F6, отриманих шляхом схрещування з вихідним сортом пшениці м’якої ‘Sumai 3’ (68 ліній з ‘Sumai 3’ QTL та 57 ліній без цього QTL), були досліджені в однакових умовах штучного зараження. Для обох груп ділянки заражували під час цвітіння суспензією односпорових культур F. graminearum, підтримуючи вологість до 100%, щоб сприяти розвитку захворювання за допомогою системи дрібнодисперсного зволоження. Через тридцять днів після зараження підрахували кількість колосків, інфікованих F. graminearum, на колосі десяти рослин на кожній ділянці; пошкодження виразили показником зараження фузаріозом (кількість випадків ураження  ступінь ураження / 100, де ступінь ураження = кількість інфікованих колос­ків / загальна кількість випадків ураження  100 та кількість інфікованого колосся / загальна кількість колос­ся  100). В обох випадках пізнє цвітіння було ключовим чинником, здатним обмежити ураженість хворобою. Попередні дані стосовно впливу Qfhs.ndsu-3BS QTL не виявили відмінності між двома групами вдосконалених ліній.
