Prospects of using bioresource potential of Adygei branch

Abstract

The paper substantiates the need to preserve and replenish the diversity of subtropical and southern fruit crops in the foothills of the North-West Caucasus. There is a list of species, cultivars, and breeding forms collected at the Adygei branch of the FSBSI Russian Research Institute of Floriculture and Subtropical Crops; this list is represented by 85 samples that are promising for breeding use and introducing into production. Their brief biological characteristics are given. Tea, persimmon, jujube, papaw, walnut, hazel, filbert, chestnut, pecan, apple, shrubby cinquefoil, etc. are considered among the promising crops. The studied plants are observed in accordance with generally accepted methods. According to a long-term assessment of the crops introduced in the conditions of the given branch, they showed their high resistance to a complex of adverse climatic and abiotic environmental factors, which contributes to the expansion of their cultural range and range of products in the region.
