| Abstract | In this article we consider the possibility of breeding of Ukrainian highly adaptive and highly productive seedless grape varieties using the best introduced, geographically and genetically distant genotypes. Based on the main modern trends in grape breeding and the necessity to replenish autochthonous assortment of seedless varieties, 35 grape cultivars from 12 countries were evaluated according to a development level of seed traces. The National Center for Plant Genetic Resources of Ukraine registered a database of seedless grape varieties. A possibility of effective use of modern breeding and natural genetic diversity regarding stress factors in order to develop successful strategies for the selection, creation, and propagation of grape varieties which are the most adaptive to specific cultivation conditions was demonstrated. Methods of performing the breeding task were optimized by modeling the main selection criteria and determining the correlation between traits of interest. Following highly productive, ecologically plastic seedless genotypes, which showed traits at a level not lower than the one set by the model in conditions of the Northern Black Sea Coast (yield not lower than 12 t/ha, marketability not lower than 70%, average weight of bunch not less than 350 g, etc.), stood out: “Kishmish tairovskii”, “Mechta”, “Beogradska besemena”, “Mars”, “Marquis seedless”, “Jupiter”, “Venus”, “Kishmish luchistii”, “Rusensko bez seme”, “Rusalka 3”, “Flame seedless”, “Gleanora”, “Attika”. Potential applications of these cultivars in the breeding process as parent varieties in creating seedless, highly adaptive and productive Ukrainian varieties were determined. | ||
