Purpose. To determine the content of biochemical compounds in fruits of M. domestica Borkh. varietal samples, select the most promising ones for use in further breeding, and recommend for use in various directions, given the biochemical complex of signs, taste and marketability of the fruit. Methods. We used generally accepted methods for determining the biochemical composition of fruits (soluble so­lids (SSR) according to GOST (State Standard System) 29030-91, total sugars according to GOST 8756-13.87; polyphenol composition according to the method of L. I. Vigorov (1968), vitamin C according to the method of A I. Ermakov (1972); tit­rated acids – according to GOST 25555.0-82). Results. Nine cultivars of apple trees were analyzed for the biochemical composition of fruits, namely the apple tree cultivar ‘Vydubytska Plakucha’ (‘V. p.’) and various hybrids created on its basis from the collection of the fruit plant acclimatization department of the M. M. Hryshko National Botanical Gardens of National Academy of Sciences of Ukraine. Selected forms are sources of 1–5 important biochemical characteristics (solids content, glucose, sugars, ascorbic acid, titratable acid) and promising for use in breeding. According to the dry matter content – the lowest rate was found in hybrid ‘V. p.’ × ‘Renet Symyrenko’ (16.68%), the highest in the hybrid – ‘V. p.’ × ‘Renet Oranzhevyi Coksa’ (22.87%), rates of ascorbic acid content varied within (6.0–12.25 mg%), total sugars (10.37–18.23), acids (0.74–1,67 respectively). The most interesting for introduction and breeding are hybrids with a high content of biochemical parameters, namely: ‘V. p.’ × ‘Renet Oranzhevyi Coksa’, ‘V. p.’ × ‘Golden Delicious’ and ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’. Conclusions. The content of the biochemical composition of the fruits, taste and marketability were characterized, and varietal samples of hybrids of the apple tree ‘Vydubytska Plakucha’ were distributed in the directions of use in order to improve the quality of life of the population. According to the biochemical indicators of the cluster analysis of the studied apple hybrids, close relationships were found between the three groups necessary in the future for breeding when selecting parental forms for an improved biochemical composition of the fruit (including hybrids ‘V. p.’ × ‘Renet Oranzhevyi Coksa’, ‘V. p.’ × ‘Golden Delicious’ and ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’, titrated acid hybrids ‘V. p.’ × ‘Starkrimson’, ‘V. p.’ × ‘Parmen Zymovyi Zolotyi’ and ‘V. p.’ × ‘Renet Symyrenko’, tannins hybrids ‘V. p.’ × ‘Slava Peremozhtsiam’ and ‘V. p.’ × ‘Starkrimson’); and to expand the assortment of apple trees according to the planned commercial signs. Hybrids of the apple-tree cultivar ‘Vydubytska Plakucha’, created in the NBG using old and valuable modern apple-tree cultivars, indicate the promise of producing high-yielding, large-fruited varieties with a high content of biologically active substances

Определить содержание биохимических соединений в плодах сортообразцов M. domestica Borkh., отоб­рать наиболее перспективные с целью использования в дальнейшей селекции и рекомендовать для применения в различных направлениях, учитывая биохимический комплекс признаков, вкусовые и товарные качества плодов. Методы. Использовали общепринятые методики определения биохимического состава плодов (растворимые сухие вещества (ССР) – по ГОСТ 29030-91; общие сахара – по ГОСТ 8756-13.87; полифенольный состав – по методике Л. И. Вигорова (1968), витамин С – по методике А. И. Ермакова (1972); титрованные кислоты – по ГОСТ 25555.0-82). Результаты. Были проанализированы девять сортообразцов яблони по биохимическому составу плодов, а именно сорт яблони ‘Видубицька плакуча’ и созданные на ее основе различные гибриды из коллекции отдела акклиматизации плодовых растений Национального ботанического сада (НБС) имени Н. Н. Гришко НАН Украины. Отборные формы являются источниками 1–5 важных биохимических признаков (содержание сухих веществ, глюкозы, сахаров, аскорбиновой кислоты, титруемой кислоты) и перспективные для использования в селекции. По содержанию сухого вещества самый низкий показатель обнаружен у гибрида ‘В. п.’ × ‘Ренет Симиренко’ (16,68%), самый высокий – у гибрида ‘В. п.’ × ‘Ренет оранжевый Кокса’ (22,87%), показатели содержания аскорбиновой кислоты варьировали в пределах 6,0–12,25 мг%, общие сахара – 10,37–18,23, кислоты – 0,74–1,67, соответственно). Наибольший интерес для интродукции и селекции составляли гибриды с высоким комплексом содержания биохимических показателей, а именно: ‘В. п.’ × ‘Ренет оранжевый Кокса’, ‘В. п.’ × ‘Голден Делишес’ и ‘В. п.’ × ‘Пармен зимний золотой’. Выводы. Охарактеризованы содержание биохимического состава плодов, вкусовые и товарные качества и распределены сортообразцы гибридов яблони ‘Видубицька плакуча’ по направлениям использования для улучшения качества жизни населения. По биохимическим показателям в результате кластерного анализа исследованных гибридов яблони обнаружены плотные взаимосвязи трех групп, необходимых в будущем для селекции при отборе родительских форм на улучшенный биохимический состав плодов (в частности, по высокому содержанию сухого вещества выделено гибриды ‘В. п.’ × ‘Ренет оранжевый Кокса’, ‘В. п.’ × ‘Голден Делишес’ и ‘В. п.’ × ‘Пармен зимний золотой’, по содержанию тит­руемых кислот – гибриды ‘В. п.’ × ‘Старкримсон’, ‘В. п.’ × ‘Пармен зимний золотой’ и ‘В. п.’ × ‘Ренет Симиренко’ по содержанию дубильных веществ – гибриды ‘В. п.’ × ‘Слава Победителям’ и ‘В. п.’ × ‘Старкримсон’) и для расширения сортимента яблонь по запланированным коммерческим признакам. Созданные в НБС гибриды сорта яблони ‘Видубицька плакуча’ с использованием старых и ценных современных сортов яблони свидетельствуют о перспективности получения высокоурожайных, крупноплодных сортов с высоким содержанием биологически активных веществ.

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.
