“…Появление многочисленных сортов порождает необходимость подбора лучших из них применительно к внешним условиям конкретных территорий, а также формата хозяйствования и природопользования [7]. В районах с суровыми климатическими условиями Урала селекционерами достигнуты большие результаты по селекции яблони [6,7], но совершенствование сортимента адаптивными сортами нового поколения, пригодными для интенсивных технологий возделывания с конкурентоспособными плодами на рынке, по-прежнему является актуальным [8].…”

The study of variability in the chemical composition of fruits under the influence of external factors is important both in terms of adaptation processes of fruit plants and for practical purposes. In this research, we aimed to carry out a comparative analysis of the biochemical composition of apples of such zoned varieties, as Ekrannoe (autumn ripening), Blagaya Vest’ and Krasa Sverdlovska (winter ripening). The trees were growing in different agrocenoses: in a horticultural research station (conventional extensive cultivation) and in a farm (intensive cultivation). For all the studied apple varieties, the content of insoluble nutrients (1.4–1.6 g/100 g), as well as the level of flavonoids (0.4%) and titratable acidity (1.5–1.7%) for winter fruits, were characterized by the lowest variability among other indicators. These indicators, therefore, can be considered species-specific. The level of polyphenols and antioxidant activity of winter apples can be considered variety-specific indicators for Blagaya Vest’ (0.52–0.53 mmol/l gallic acid equivalent; 71.2–75.9%) and Krasa Sverdlovska (0.65 mmol/l gallic acid equivalent; 89.7–90.1%), respectively. In all apple varieties, the contents of organic acids, vitamin C, dry matter, sugars and mineral elements showed the greatest dependence on growing conditions. In winter varieties, this list also included the sugar/acid ratio. In terms of biochemical composition, autumn-ripening apples proved to be more responsive to changes in external environmental factors.

Currently, new varieties are subject to strict requirements for adaptability, productivity, commercial and consumer qualities of fruits. In this regard, it is important to study the interaction of the genotype of apple tree varieties and forms with climatic conditions, and it is also necessary to assess the genotypic variability of economically valuable traits focused on identifying genotypes characterized by stability of fruit quality in growing conditions. The study examined 12 varieties and forms of apple tree, selected by the Orenburg branch of the FGBNU FNTs of Horticulture. The following signs were studied: useful ovary (%), number of fruits (pcs.), average fruit weight (g), productivity (kg/d), sugar content in fruits, soluble solids, ascorbic acid, determination of titrable acidity. The study used mathematical models of two-factor variance and cluster analysis by the Ward method. Statistically significant differences were observed in the number of fruits between the first and third, and second and third clusters (t = 4.01 and 4.35, at p<0.01, respectively), as well as productivity between the first and third clusters (t = 9.19 at p<0.01), second and third (t = 8.7 at p<0.01).
