摘要：The goal of research – signification of influence of the genotype of rootstock varieties on the vegetative and reproductive characteristic of the Purple early (Fioletoviy ranniy) grafted grape variety during adaptation in the field. Observations of research was made with using rootstock varieties - PP 101-14, Kober 5BB, Vierul-3. The influence of the rootstock genotype was introduced on the basis of by the survival rate of bushes, plant growth characteristics of the Purple early (Fioletoviy ranniy) variety, and uvological properties. The least death of bushes was found by usage the rootstock Vierul -3. Was revealed influence of the rootstock genotype on the vegetative measures of the grafted variety. The genotype of the Vierul - 3 rootstock variety was materially affected the leaf-area and leaf-area duration of the bush. Was found that influence of rootstock on the reproductive properties of graft - rootstock combinations. Grafting on the rootstock Cober 5BB foster the increase slightly of yield per Bush. Uvology indicators point at a positive effects of rootstock Vierul-3 on the weight of cluster and berries, the size of cluster and berries, the structure and form of the cluster and total sugars. On-farm research of agrocenosis, is advisable to graft the rootstock Vierul-3 for Fioletoviy ranniy variety.
