Abstract This article presents new wine hybrid forms bred in NSC «Tairov Institute of Vityculture and Winemaking» for high quality winemaking and creation of local wines with exclusive taste and aromatic characteristics. Further development of the viticulture and winemaking industry requires qualitative changes that would increase the competitiveness of viticulture and wine product. The development of viticulture and winemaking in Ukraine demand the improvement of the grape assortment based on new generation varieties adaptive to specific growing conditions. Improvements of the grape assortment can be achieved mainly by using the method of interspecific directed hybridization, based on the crossing genotypes from different eco-geographical zones. Thus, new varieties of grapes are created, which combine properties and characteristics of parental forms and contribute to the increase in the quantity and quality of products, as well as the resistance to biotic and abiotic environmental factors. In addition to high resistance to diseases and pests, these genotypes are characterized by increased adaptability to climatic conditions. The article presents the results of phenological observations and the main agro biological indicators of 5 hybrid forms of complex interspecific origin. Genotypes, which showed a level of the above-mentioned characteristics not lower than the estimated one under conditions of the Northern Black Sea Region, were preliminarily selected. The analysis of the experimental data obtained during the three-year field experiment. In this article influence of biotic and abiotic factors on the studied varieties was investigated. The level of resistance against fungi diseases is defined as one of the main criteria for suitability of a variety for environmental (adaptive) viticulture. Obtained data show a level of manifestation of such important traits as frost resistance, cold hardiness, drought resistance, productivity. The level of qualitative characteristics of product of new hybrid forms is determined. The complex of signs of interest demonstrated the most promising genotypes for further registration. Analysis of the obtained data allows us to make conclusions about prospects of ‘Yarilo’, ‘Odesskiy zemchug’, ‘Charivniy’ и ‘Selena’ varieties under conditions of 2012-2014 vegetation periods.
