Agroecological zoning of perennial crops is based on their requirements for weather conditions in the "genotype-environment" system, taking into account the adaptation of each culture in the cultivar aspect. The phenological method based on plants interaction with a complex of factors, through a multiple model, determines the influence of each environmental factor on the cultivars yield. Ecological indicators indicate specific reactions of the cultivars to changes in weather conditions. According to the above methods of agroterritories zoning in the humid subtropics, the paper grounds the criteria that will estimate zonal agro-ecological resources for peach crop, which is necessary in order to predict its location in mountainous conditions. The following cultivars adaptive in the zone were established: Summerset (early maturing), ‘Redhaven’, ‘Krasnaya zarya’, ‘Larisa’ (mid-ripening), ‘Veteran’ (late).
