Comparative performance of different grafting techniques in grape cv. Pusa Urvashi

Abstract

Rootstocks have become a major component in present day viticulture. Till date, there are several rootstocks evolved of which some have become commercial in many advanced countries. Different types of grafting and budding methods have been tried in grape with varying success rates. Hence, to standardize the same for Pusa Urvashi, different rootstocks (Dogridge A, Salt Creek, 1613 and H-144) involving different grafting methods (wedge, side and bench grafting) were tried. The grafting factors like month (February, March and August) and grafting height (15, 30 and 45 cm) were standardized using one-year-old rootstocks under glasshouse conditions. The highest graft take success was registered in wedge followed by side in all the three months, while for bench grafting, the highest graft take was recoded in the month of February. The graft take was the maximum at the height of 30 cm, while the minimum was noted at 15 cm. Of the three grafting months, February was found the best with respect to percentage graft success and survival. Dogridge A as rootstock was proven most compatible with Pusa Urvashi as compared to other rootstocks.
