“…Despite the fact that in recent years there has been a tendency for its reduction [1,2], various methods and ways of improving its efficiency and significant acceleration are still relevant [2][3][4][5]. One of the ways to achieve high breeding results in the world in the shortest possible time for the most valuable fruit plants, including the apple tree, is an in-depth study of the entire genetic potential of biological resources of crops, especially with the use of modern methods of molecular genetics, cytology, biochemistry, information technology, etc., for active targeted use in the breeding process [3,[7][8][9][10].…”

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).

“…The method of remote hybridization, especially interspecific hybridization, which is currently most frequently used in the breeding of the most important agricultural perennial plants, including apple trees, is aimed at improving the created sample according to the characteristics of stability and adaptability to abio-and biotic stressors of the environment, which are closely related to the manifestation of increased and stable productivity of the genotype under stressful conditions, as well as at strengthening the qualitative and biochemical composition of fruits [1][2][3][4]. Active use of the induced polyploidy and remote hybridization methods in fruit plant breeding, including their combination or sequential application, helps to enhance the diversity of qualitative and quantitative significant traits of hybrid progeny, increase the number of combinations and variations of the most important economic traits in new genotypes, increasing the probability of creating the most valuable ones for breeding and production use [2,[5][6][7]. In order to speed up obtaining the most important results for the priority goals of a long and time-consuming breeding process, most of the world's scientists successfully use the entire genetic potential of cultural biodiversity to create the latest improved genotypes of leading fruit plants, including apple trees [1,3,[8][9][10].…”

Innovations in the apple tree breeding process are associated with the study of the gene pool, the use of valuable samples for accelerated production of commercially popular domestic varieties. The purpose of the study is to identify the most valuable genotypes of the genus Malus of various origins and ploidy for the accelerated creation of domestic adaptive varieties. Modern programs and methods of breeding and variety study were used. The results of the study (2010–2020) of collection of apple trees samples growing in the conditions of the Prikuban zone of the North Caucasus region are presented. It was found that a significant decrease in yield in 2017 and 2020 in the apple tree crop as a whole (11.69–12.48 t/ha) is due to an increase in the negative complex impact of spring-summer and winter stressors on the plant. Promising samples for industrial research and breeding are identified: Gin, 12/1–21–46, 12/2–20–53, immune to scab (Venturia inaequalis (Cook) G. Winter), with increased adaptability to the complex effects of abiostressors in the region, high productivity potential (average yield 26.15–30.05 t/ha, total - 287.65–330.55 t/ha). Selected by large-fruit: Orphey, Gin, 12/1–21–6, 12/2–20–53, 12/1–21–24 (average fruit weight is 200.3–225.5 g) for further use in breeding research and creation of high-quality southern varieties.

“…The creation of the new varieties of fruit plants with the high quality and commercial indicators of fruits, especially those with a sufficient level of resistance to fungal pathogens and abiotic stressors, is a priority selection direction in the world [1,5,[10][11][12][13][14][15]. Successful creation of new varieties and forms, and finding solutions of this breeding problem is inextricably linked with the complexity of research and involvement of various specialists: breeders, variety scientists, biochemists, immunologists, etc., and also linked with selection, creation and involvement in hybridization of valuable initial parental forms, and also in-depth study of the obtained new, genetically diverse breeding material.…”

The generalized results of a comprehensive long-term assessment (2015-2019) of biochemical and technical indicators of the quality of apple fruits of promising varieties (Malus domestica x Borkh.), including: the valuable initial parental forms and new varieties of regional selection, different in ploidy and genetic origin are presented, grown in the conditions of the South of Russia. This work used the generally accepted modern methods and programs for the variety study of fruit plants developed at the North Caucasian Federal Scientific Center for Horticulture, Viticulture, Wine-making (NCFSCHVW). The aim of the study was to select the source material of the apple fruit quality, which is valuable for the breeding, and the sources of the target traits based on the analysis of longterm data on the assessment of the biochemical composition of promising varieties of different ploidy and genetic origin. As a result of the comprehensive assessment of the main indicators of the quality of apple fruits in a varietal section, the sources of significant traits of apple tree for breeding use were identified: large-fruited, bright red and pure yellow color, improved chemical composition of fruits. According to the data of a longterm studies of the quality indicators of the apple fruits of introduced varieties and varieties of selection of the FSBSI NCFSCHVW, genotypes with an improved biochemical composition were identified for the use in the selection process: diploids: Champion, Orpheus (sugar content 10.5% and 10.8%, respectively); triploids: Soyuz, Vasilisa and the diploid variety Fortuna (vitamin C - more than 10.0 mg / 100 g); diploids: Margo, Vasilisa (P-active substances - more than 110.0 mg / 100 g).
