11 training systems of trunks investigated with the row distance of planting: 3 x 0.75 m, 3.25 x 0.75 m, 3.50 x 0.75 m and 4 x 0.75 m. The observed differences in the grape yield with some investigated shapes of the trunk can be treated as statistically significant differences in comparison with other shapes which exhibited lower yields of grape. The influences of row distance on the height of the average yield is evident and follows some rulles. The increasing number of trunks per hectare obligatory gives increasing yield of grape in kg/ha. The shapes of trunks which exhibited the highest yield of grape did not realise the lowest content of sugar in grape juice. The average value of acidity in grape juice follows the ampelographic parameters for this variety.
