The studies were carried out in the temperate continental climate of southern Russia in the plantations of the Anapa ampelographic collection on the varieties Adisi, Kuldzhinsky, Tarnau belonging to the group orientalis C. Negr. It was found that the growing season duration of Adisi variety from budding to the full physiological maturity of grape berries decreased by 24 days, of Kuldzhinsky variety - by 23 days, of Tarnau variety - by 27 days. Regularities have been established that indicate a close and average positive correlation relationship between a decrease in the duration of the growing season and an increase in the sum of active air temperatures.
