Studies have shown that the clone of the Chardonnay R-10 against the background of the standard variety is characterized by higher agrobiological indicators: fruit bearing coefficient, average cluster weight, the yield from the bush exceeds the control by 1.3 times. The shoot productivity in the wet mass of the bunch in the clone of the Chardonnay R10 variety is characterized as “high”. The clone of the Sauvignon green R-3 variety showed high shoot fertility, the average mass of the bunch in the clone reaches 165.3 ± 2.2 g, exceeding the control 1.15 times, the yield from the bush reaches 4.02 ± 0.1 kg, exceeding the standard grade by 1 kg. The shoot productivity in the wet mass of the bunch is characterized as “high”. The average weight of a bunch in a clone of Muscat white R-3 variety reaches 275.3 ± 2.03 g, which is 95 grams more than the control (180.0 ± 3.2 g). The yield from the bush is 4.49 ± 0.2 kg, exceeding the standard variety by 1.7 times. The productivity of the shoot is characterized as “very high.” The degree of variation of characters in clone populations of the Chardonnay varieties R-10 (V = 2.4-9.8%), Sauvignon green R-3 (V = 1.88.7%), White Muscat R-3 (V = 1.2–9.3%) are characterized as weak, which indicates the genetic homogeneity of the studied clone populations under specific growing conditions. Technological evaluation showed that wine materials produced from introduced Chardonnay R-10 clones, Sauvignon green R-3 and White Muscat R-3 excel in quality indicators wine materials produced from standard varieties.
