In terms of winter hardiness (average for 2021-2025), the table varieties Muscat Poloskey and the control variety Vostorg with more than 85% buds preserved, the seedless varieties Sultanina and Kishmysh Nakhodka, in which 75% buds bloomed, and the technical variety Muscat Donetsk were distinguished. The table varieties Evgeniya, Muscat Poloskey, Red Globe, Kishmysh Nakhodka and the technical varieties Muscat Odessa and Rubin Tairov were distinguished by resistance to the main grape diseases of fungal etiology of not less than 6 points. A high and stable level of yield (not lower than 9-10 t/ha) over the years of the study was noted in the table varieties Tair and Vostorg, Carbonado, Rochefort and Bazhena. High yields were noted for the technical control varieties Muscat Odessa and Rubin Tairov and the Muscat Donetsk variety. High marketability among table varieties – not less than 90% of bunches – was noted over the five years of research for the varieties Slava Ukrainy, Kuban, Carbonado, Khusayne White and Tair. High tasting scores on average for 2021-2025 were received by the varieties Carbonado, Rochefort, Red Globe and Velyka. The table variety Rochefort was distinguished by a set of characteristics. Among the experimental seedless varieties, the Kishmysh Nakhodka variety and the control variety Kishmysh Tairov were distinguished by a set of economically valuable characteristics. According to the results of five-year comprehensive research on technical varieties, the Muscat Donetsk variety is distinguished by the characteristics of adaptability, productivity and product quality. The database of source and donor varieties has been supplemented with sources of the traits "winter hardiness", "pathogen resistance", "yield", "berry mass", "tasting assessment", "seedlessness", etc. Product Description popup.authors Lyudmila V.
