The purpose of the research was to study 8 Georgian and 3 Dagestan technical autochthonous grapevine varieties and identify the most productive and promising ones for high-quality winemaking in the Rostov region. The research was conducted in 2016-2019 at Don ampelographic collection named after Ya.I. Potapenko (Novocherkassk, Russia) according to generally accepted methods and state Standards in viticulture. Don autochthonous varieties Sibirkovyij and Krasnostop zolotovskij were used as controls. The soil - ordinary Chernozem carbonate. All the studied varieties had a high percentage of bud break (from 69.3% in Hotsa tsibil to 81.2% in Mahbor tsibil). The fruiting coefficient of 1.0 or more was observed in 6 varieties. The average weight of a bunch varied from 74 g (Mudzhuretuli) to 459 g (Adreuli shavi). The estimated yield was very high for the varieties – Adreuli shavi and Nakutvneuli, high – Goruli mtsvane, Hotsa tsibil, medium – Latsu kere, Grdzelmtevana, Grubela, Amlakhu, Sibirkovyij, Vernakhi and Krasnostop zolotovskij. Grapevine varieties – Goruli mtsvane, Grdzelmtevana, Grubela, Latsu kere, Hotsa tsibil, Nakutvneuli were selected as prospective due to agronomic traits and high quality of wine. These varieties are also recommended to be used in breeding for creating varieties with high technological properties for high-quality winemaking.
