In the world, huge work is being done to create global information banks of plant genetic resources. The need for conservation and rational use of genetic resources in modern conditions has become very relevant. Genetic collections are the basis for selection work: creating new varieties, replenishing the assortment with new, classic, introduced and native varieties, adapted to the natural (soil and climatic) conditions of the cultivation sites. In the Anapa ampelographic collection, 4911 varieties of various ecogeographical and genetic origin are represented, the use of which provides great opportunities for creating and breeding new varieties, their state testing and zoning. In the gene pool of the ampelographic collection, most varieties of V. vinifera L. grapes are represented by local honeycombs of different regions of the grape culture, and more than one fourth of varieties of V. vinifera L. are obtained from intraspecific crossings. Despite the value of local varieties of grapes, they do not always meet all the requirements of production. Therefore, to improve the local assortment, it is necessary to carry out selection - breeding new varieties of grapes. This article presents the long-term results of the work on the selection of varieties of table and technical directions in the Anapa ampelographic collection used for breeding. Also, the role of the genetic collection in the creation of new generation varieties by combinative selection is shown - as donors for creating new varieties of grapes. Dedicated varieties are the sources of valuable traits, which are given primary importance and are especially important for the viticulture of the Russian Federation

A variety determines the direction of use of grape products and plays a leading role in improving its quality. Preservation of genetic resources of grapes and their studying are very important for modern science. The studied material makes it possible to use the selected genetic characteristics for breeding new varieties of grapes, taking into account the requirements, and introducing them into production, as well as highlighting the most valuable varieties for transferring them to the state variety testing. Among a wide variety of grape varieties, in the ampelographic collection there are varieties of AZOSVIV selection of the technical direction: Krasnostop AZOS and Dostoiniy, for which complete phenotyping was carried out. The phenological and agrobiological information on the grape varieties studied for 2015- 2017 is collected. The presented grades of grapes of the technical direction are characterized by high quality of production. The wines from the varieties Krasnostop AZOS and Dostoiniy are competitive, characterized with high consumer properties; they enjoy the well-deserved fame and were nominees of exhibitions and holders of diplomas repeatedly. Based on the results of microsatellite profiling, the varieties showed a sort-specific general combination of alleles. At the same time, in each locus there is one identical allele, which corresponds to the fact that the varieties Krasnostop AZOS and Dostoiniy have one common parent (Phylloxer-resistant Gemete). The received formulas of a variety (DNA-passports) in practice can be effectively applied to determine the cleanliness of planting stock and plantations of grapes, specification of the parent forms of the sample and in the disputed questions of the authorship of the variety. The study was supported by Federal Agency for Scientific Organizations program for support the bioresource collections
