Abstract

The yield properties of different scion/rootstock combinations for cv. `Cabernet Sauvignon` (Vitis vinifera L. cv. `Cabernet Sauvignon`) were evaluated. The experiment was set in the Vipava Valley as a randomised group trial. The planting material was cv. `Cabernet Sauvignon` standard selected in Slovenia and clones 191 and 15 of French selection. The rootstocks inspected in the combinations with scions were `Kober 5BB`, `SO 4` and `420 A Mgt` (V. berlandieri Planch. x V. riparia Michx.),  `1103 Paulsen` (V. berlandieri Planch. x V. rupestris Scheele.) and `3309 Couderc` (V riparia Michx. x V. rupestris Scheele.). The vines were trained on double Guyot and monitored during 2001 and 2002. At the harvest the yield/vine and number of bunches/vine were recorded and the sample of 100 berries/vine was taken. The samples of berries were weighed and analysed for grape sugar and acids content. During the dormant season one-year-old canes were weighed. Data were statistically analysed using the one-way analysis of variance. The standard material showed greater vegetative and productive potential than cl. 191 when both were grafted onto `SO 4`. The consequence was lower grape quality for standard. Although the differences in productivity and grape quality between standard grafted onto different rootstocks were not significant it was obvious that `1103 Paulsen`, in comparison with `SO 4` and `420 A Mgt`, significantly increased the vegetative growth of scion.  The difference in the yield/vine between standard grafted onto `Kober 5BB` and cl. 15 grafted onto `3309 Couderc` was unstable but with the former combination better grape quality was achieved and one fold higher pruning weight/vine was detected in both years.
