Socio-economic and climatic changes require replenishment of assortments with new, adaptive and technological varieties. To the full, this applies to grapes. Consumers and producers of grape products prefer varieties with exclusive taste indicators, mandatory large-fruited and large-sized. Today's seedless varieties are very popular in the market. It is extremely important for today to maintain the ecological purity of agricultural products, including table grapes. This is possible if the pesticide load of the planting is reduced. New-generation varieties obtained through complex crosses using several types of Vitis have genetically determined disease resistance of at least a relative level. This reduces the number of spray from 10-12 to 5-7. And with the use of crossbreeds of Amur frost-resistant varieties, they also get increased endurance to wintering conditions. Today, grape varieties that can withstand up to minus 40 degrees frost can co-exist with the major pathogens without sacrificing their quality. At the same time they have exclusive economic indicators - seedlessness, large-fruited and coarse-grained, exclusive taste and aroma, etc. In 2017, a number of crossings were conducted to identify donor varieties of valuable traits and enrich the domestic grape gene pool, in which 6 varieties were attracted, which had a high manifestation of interest and were promising as donor varieties of these traits. The best of will add to the base of donor varieties of valuable characteristics and properties of grapes.
