Description	The drought tolerance is a very important property of grapevine rootstocks. For that reason the breeding and selection of new rootstock varieties is focused also on the evaluation of their drought tolerance. In this experiment, altogether 20 new hybrids and 4 existing rootstock varieties were compared and evaluated. The experimental scheme involved 3 variants of water supply. Evaluated were the following properties: growth intensity of annual shoots, CCI (chlorophyll content index) and visual characteristics of plants. The most resistant were hybrids from the pedigree groups C (Binova x Borner), D /Binova x /(Binova x Teleki 5C/) x Borner/, and F (Teleki 5 C x B?r). The following hybrids were classified as drought-tolerant: 17-1-6 (C); 17-1-9 (C); 17-6-2 (C); 17-6-9 (C); 17-8-2 (D) and 9-20-1 (F). Based on obtained experimental results and also on correlations existing between individual traits it can be concluded that practically all traits under study may be used when evaluating the resistance of plants to drought. The obtained results indicated that the Borner rootstock (and thus also the species Vitis cinerea) can be used as a suitable genetic resource for the purpose of the breeding grapevine rootstocks for tolerance to drought.
