Abstract: This influence of various rootstocks on the yield and grape composition of Sauvignon Blanc was examined. The yield on rootstock 41B/72 was 1 kg/vine or more higher than on rootstocks SO4 cl. 31, Riparia cl. 1 and Kober 5BB. The vines grafted on the Börner rootstock gave the highest weight of 100 berries (241 g). The highest seed weight of 100 berries (6.9 g) was found on rootstock 196/17 Cl, while the lowest one was on the Riparia cl. 1 (5.6 g). There was a strong, positive correlation (r = 0.91) between the berry and seed weights of vines on rootstock 41B/72 (2003). The total acidity content and the relationship between tartaric and malic acids were affected more by the weather conditions than by the rootstock. Relatively strong correlations between the grape yield and total soluble solids (r = -0.89), and between grape yield and total acidity (r = 0.76) were found in the grape juice on rootstock 41B/72 (in 2002).
