PROMISING OFFSPRINGS OF PLATOVSKY GRAPEVINE VARIETY

Сreation of new, well adapted to the limiting factors of the natural environment, high-quality grapevine varieties is relevant and contributes to the implementation of a new federal project "Stimulating the development of viticulture and winemaking in Russia". The article consid-ers the agrobiological characteristics of white technical hybrid forms of grapevine bred by ARRIV&W − branch FSBSI FRARC – off-springs of Platovsky variety – a donor of valu-able traits. Based on the results of agrobiologi-cal and uvological studies, the ripening dates of berries were determined, the most winter-hardy ones were identified − Izumrud, Muscat Pla-tovsky, Nectariу and 2-16-5-9; productive − 2-15-4-9 and Muscat Platovsky; on the high yield of juice - 2-15-4-6 and 2-16-2-3. High-quality wines were obtained from hybrid forms Izumrud, Nectariу, 2-15-4-9. The conducted studies made it possible to recommend 2-15-4-6, 2-15-4-9, 2-16-5-9 and 11-28-4-4 for further study with subsequent transfer to the State testing and use in breeding as initial forms of valuable traits. Izumrud and Nectariу have been transferred to the State Test, and Muscat Platovsky is being prepared for transfer in 2023.
