The article presents the results of three years of studies
on regenerative processes in technical white one-bud
cuttings of resistant varieties of grapes Bianca, Viorica
and Riton. The studies were conducted in greenhouse
experiments at the Department of Viticulture of Kuban
State Agrarian University. It was found, that the
cuttings of Viorica varieties had achieved the best
ripening, and the worst was Bianca. Varieties of
Viorica and Ryton which have rather good level of
ripening of the cuttings, had starch in carbohydrates
and Bianca variety had sugar. Earlier blooming of
buds characterized the cuttings of Ryton. Blooming of
the buds of Bianca somewhat delayed. Maximum
length of the shoots characterized the cuttings of
Bianca, and the lowest – Viorica. The shortest pre-root
period (26.3 days) was observed in Ryton, and the
longest (29.3 days) – in Bianca. Viorica was
characterized by the highest yield of cuttings with 3
roots and more (81.3%), this indicator was a bit less
(72.5%) for Ryton. For Bianca it was minimal and it
was 26.3%. A similar pattern was observed for the
average number of cuttings formed at the roots: the
variety Viorica - 9.4 pc.,Ryton - 8.1 pc. and Bianca -
4.3 pc. Thus, cuttings of the varieties of Viorica and
Ryton belong to a group with a very high root growing
activity and Bianca has an average activity
