The purpose of the study is to study the diversity of manifestations of adaptability, productivity and quality traits and the selection of stress-tolerant and resistant forms and clones. The conditions of the 2021 growing season significantly deviated from the optimal parameters for the grape plant. The minimum temperature in winter did not fall below 21 degrees below zero, however, the aftereffects of the drought of the previous two growing seasons against the background of a decrease in temperature caused the loss of buds by up to 53% on table varieties and up to 74% on technical The varieties and forms Vostorg, Kalisto, Tairyan, Kardyshah Tairovsky, Fontan, Zagadka, Original, Primorsky with the opening of 65-75% of buds stood out. Among the experimental group of technical varieties and forms, the forms 62-16-32, 56-62-39 and 58-12-6 stood out. A significant group of experimental varieties and forms, which included the control varieties Kometa, Kesha, Original and Zagadka, even in epiphytotic conditions showed resistance not lower than the relative level - 6 points on a 9-point scale. The resistant control varieties Vostorg and Augustin stand out with resistance at the level of 7 points on a 9-point scale. The same group included the forms 58-43-27, 59-17-52, 59-20-55. It is necessary to highlight the promising form Kalisto, the average resistance score of which was more than 8 points. The group of experimental technical varieties and forms showed a level of resistance not lower than the relative, that is, not lower than 6 points on a 9-point scale. The highest resistance was observed in the control varieties Skoda, Illichivskyi early, Rubin Tairovskyi, Zagrei and Muscat Odessa and the form 56-8-84 - the average resistance score is more than 7.0.
