Influence of Different Rootstocks on Vine Growth, Cane Storage, and Yield in Crimson Seedless Grapevine

The study investigated the influence of different rootstocks (Dogridge, 110R, 140Ru, and 1103P) on vine growth, cane storage, and yield in Crimson Seedless grapevines during 2021-22 and 2022-23 at ICAR-NRC Grapes, Pune. Growth parameters, including pruned biomass, leaf area, and stock: scion ratio, were significantly impacted by the rootstocks, with Dogridge rootstock recording the highest values. Dogridge also resulted in greater shoot length, shoot diameter, and minimum internodal length. Cane biochemical content, such as total phenol, tannin, proline, and carbohydrates, was highest in vines grafted on Dogridge, while 1103P rootstock showed the highest cane protein levels. Yield parameters, including average bunch weight and yield per vine, were superior in vines grafted on Dogridge. The study concluded that Dogridge rootstock significantly enhanced cane storage, biochemical composition, and yield, making it a suitable choice for Crimson Seedless grapevines in tropical conditions.
