There is still apprehension in the grape growers mind that which rootstock has more beneficial effects with respect to sustainable yield and quality and also the longevity of the vine. Thompson seedless was grafted on Dog Ridge, 110R, 99R, 1613C, St. George and Salt Creek and was compared with own rooted Thompson seedless for bud fruitfulness. The results revealed the significant differences with respect to rootstock and bud position. Among the different rootstocks, general performance of the and also the microscopic studies showed that the rootstock 110R can be the alternative to the present Dog Ridge rootstock which is popular among the grape growers of Maharashtra.
