“…Varieties with a constant and high sugar content are of value. In our studies, a high sugar content was observed in the forms 18-31 (14,2 -13,2 %), 5-1 (14,0 -12,5 %), and 1-31 (13,6 -12,8 %) [11].…”

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).

“…The combination of high parameters of adaptation and resistance of the apple plant to biotic and abiotic stress factors and their complex is important for a more successful realization of the productivity potential of modern assortment grades. The data we obtained [14,19], as well as the data of a number of Russian scientists, confirm that that quite often the grades of domestic breeding are superior to foreign ones in adaptability to the complex of stress factors in the cultivation region [33][34][35].…”

The breeding renewal of the apple assortment in the conditions of southern fruit growing in Russia on the basis of domestic achievements is due to the acceleration of the breeding process associated with an in-depth study of the existing gene pool of culture, the widespread use of the samples most valuable in terms of the quality of the products obtained to create commercially demanded grades of regional breeding. The aim of the study is to isolate, on the basis of a long-term comprehensive study in the conditions of the Western Ciscaucasia, valuable specimens of the genus Malus to enhance the efficiency and accelerate the process of creating adaptive and high-quality grades of regional breeding. The work was carried out using generally accepted and modern programs and methods of variety study and selection of perennial fruit crops (apple trees). The long-term results of the study for 2010-2020 are summarized. in the conditions of the Kuban zone of the North Caucasian region of gardening of collection specimens of apple trees. Established that the increase in high-temperature stressors, the deficit in August of precipitation (28.2 mm) in recent years (2010-2020) has a negative impact on the growth, development and ripening of fruits, the laying of generative buds of the next year’s harvest. The weather conditions that have developed in the region, which are not sufficiently favorable for apple plants, make it possible to select drought-resistant, high-yielding, stably fruiting grades with commercially valuable fruits. Highlighted with high productivity potential diploids: 12/1-21-60, 12/2-20-22, 12/2-20-75 and triploids: 12/2-21-35, 12/2-20-56 (average yield 28.06-34.08 t/ha; total – up to 374.88 t/ha). Diploids were distinguished by large-fruited: Orpheus and 12/1-21-60 (average fruit weight 202.3-204.5 g, maximum – 224.8-278.8 g) and triploid varieties and elite forms (from the family of Idared × Balcgard 0247E): 12/2-21-35, 12/2-20-56, 12/1-21-27 (average fruit weight 201.4-317.9 g, maximum – 286.5-387.2 g).

“…VNIISPK makes a great contribution to the implementation of the set tasks by introducing scientific achievements in breeding new disease-immune, triploid, high-quality apple varieties and improving technology elements in intensive plantings [22,23]. Long-term study of new scab immune, heteroploid varieties of different ripening periods, including early summer ones in terms of basic production and biological indicators, allows to recommend the best of them for modern intensive plantings, farms and homestead orchards (Table 11).…”

The study results of the main economic and biological indicators of summer ripening apple varieties on low-growing rootstocks in intensive plantings were generalized. It was found that the use of low-growing intercalars has the same weakening effect on the apple tree growth as when using it as a rootstock. In terms of the total yield, 10-year-old trees of the Orlinka and Yablochny Spas varieties did not show significant differences in the options for using low-growing forms in as an intercalary or root stock. Modeling the damaging factors of the winter period revealed good resistance to early winter frosts, to a decrease in the freezing temperature in the middle of winter to -40 °C and to frosts after thaws at the end of winter. On the medium-sized rootstock 3-3-72, Rannee Aloe variety showed high early ripening and productivity significantly higher than Papirovka. The highest yields of the studied varieties on the rootstock 3-3-72 were given at the age of 10 to 20 years and are characterized as mildly periodically fruiting. According to the complex of economic and biological indicators, the varieties of summer ripening period for intensive plantings, farm and homestead gardens were identified.
