Entry into the international market today is only possible with genotypes that are able to consistently provide high quality, environmentally friendly and exclusive products. A comprehensive, comprehensive evaluation of new introduced varieties will help highlight the best for conditions the Northern Black Sea Coast and use them as a parent component in crossbreeding. In the collection of NSC "V.Ye. Tairov Institute of Viticulture and Wine-making" for today more than 700 varieties, both classical intraspecific and complex interspecific origin. Many of them are involved and involved in the breeding process. Among Vitis species, vinifera species have the lowest adaptive potential. Therefore, as potential donor varieties of adaptability traits, complex interspecific genotypes are taken into account, which include several Vitis species in their calculated genetic formula. Cleavage and variability of traits in the offspring of such non-permanent gene structures can give the desired combination of genes and therefore the level of adaptability. Investigation of the level of manifestation of valuable traits in future parental varieties using the method of genetic analysis, comparing the results of phenological, agrobiological and immunological observations in the field, will allow to identify the genetic conditionality of traits and to determine the prospects of variety for further use and breeding the potential of complex interspecific hybrids. The main purpose of the research is to create scientific and methodological foundations for the detection and possibility of imitation of the level of manifestation of adaptive properties on the basis of allochthonous and autochthonous varieties and clones of grapes.
