The main purpose of the study was to investigate the the level of manifestation of interest feature of a group of promising genotypes at different stages of the breeding process in comparison with the data of control varieties. Five hybrid combinations for major traits of interest have been described to determine patterns of inheritance and variability in offspring. The best genotypes are selected for further study in terms of overall plant development, yield, bunch size and berries, taste properties and resistance to major fungal diseases. Among the prospective table grape and technical forms studied are the genotypes, which in the conditions of the 2017 growing season showed a high level of winter hardiness and frost resistance, prolificacy and productivity, the size of the bunch and berries, complex resistance against diseases. The level of manifestation of the main economic values in the selected genotypes corresponded to or exceeded the level of control varieties. And the perspective clones of grape varieties, which are allocated according to the study for features of interest, outperformed the average data for a group of clones of one variety. Research of genetically heterogeneous populations will be continued to confirm the stability of the level of manifestation of traits in vegetative periods with different weather conditions.
