Table grape rootstocks in South Africa

The state of rootstock use in the various South African table grape regions is indicated in Figure 6 and Table 1. Figure 6 shows the contribution of the six most cultivated rootstocks, with Ramsey by far in the first position in all regions. The Western Cape has the highest percentage of plantings with Ramsey as rootstock, followed by the Lower

Orange River region and the Northern Provinces R 110 is in the second position in all regions, with the largest plantings (25%) found in the Northern Provinces. This can be attributed to favourable growing conditions regarding climate and soil in these provinces. R 99 still plays a significant role in the Olifants River region, while the use of US 8-7 is limited.
