“…To successfully solve these important problems for fruit crops in the modern world, it is still important to use classical methods: distant hybridization, including interspecies, rehybridization, polyploidy, spontaneous and induced mutagenesis, etc. The use of interspecific hybridization is aimed at improving the commercial attractiveness of the material being created and the biochemical composition of the fruits, enhancing the signs of resistance to bio-and abiotic stress factors, which is associated with high productivity and stable fruiting of the obtained sample under the influence of stressors [3,10,11]. Classical breeding methods of induced polyploidy, clone breeding, induced mutagenesis and distant hybridization can enhance the biodiversity of the resulting hybrid material, increase the number of different variations in the combination of leading agrobiological traits in hybrid offspring, accelerate and increase the likelihood of obtaining valuable samples [5,6,12].…”

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).

“…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]. The breeding use of only a small number of initial forms leads to a serious decrease in the resulting biodiversity, hindering the successful solution of breeding problems [8].…”

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.
