Abstract: An investigation was carried out on the effect of roostocks on Anab-e-Shahi grape employing the rootstocks St. George, Teleki 5-A, Dogridge, 1616, 1613 and Gulabi in comparison with own-rooted vines to identify the most suitable rootstock. Rootstocks Dogridge and 1616 were found to impart vigour to Anab-e-Shahi grape but adversely affected the yield and yield attributes. Rootstock Gulabi lowered most of the vigour attributes and resulted in the highest yield. St.George and 1613 similar vigour attributes as own-rooted vines, but influenced the yield favourably. Rootstocks Gulabi, 1613 and St. George increased the yields through increased fruitfulness of canes. Fruit quality parameters were not influenced by any of the root stocks. Higher levels of total and NC3- N were associated with lower yields in the rootstocks Dogridge and 1616 and it was reverse in Gulabi. St. George appeared to be an ideal rootstock for economizing N inputs. Higher petiole K contents during June were associated with higher yields. Lower Mg and higher Zn contents were in general associated with higher yields. Rootstocks Dogridge, 1616 and St. George had low levels of chloride content and may be suitable for areas with high chloride in irrigation water. Among the petiole nutrients, NO3-N, Mn, K and Zn contents in June and total N, Mg and CI in December were found to be useful in yield prediction. Leaf sampling in June may be useful to work out relationship between petiole nutrient contents and yields under double pruning and single cropping conditions. Rootstock Gulabi may be employed to increase productivity of Anab-e-Shahi grape. St. George and 1613 are useful on sodic soils and in locations where irrigation water has high chloride content.
