A pot culture experiment was undertaken in 2000-01 in Rahuri, Maharashtra, India, to investigate the relative drought tolerance of grape rootstocks (Dogridge, Salt Creek, 1613-C, 1616-C, 1103-P and SO4) on the basis of relative leaf water content (RLWC) and morphological characters, under 3 levels of irrigation regimes (0.3, 0.5 and 0.7 bar). The maximum height of shoot (66.50 cm) was observed at 0.3 bar irrigation scheduling in Dogridge. The maximum diameter of shoot (4.20 mm) was observed in 1613-C with irrigation scheduling at 0.3 bar; whereas Dogridge attained the highest diameter of shoot (3.35 mm) with scheduling at 0.5 bar. The maximum number of shoots per vine (19.12) was observed in 1613-C, whereas 1103-P had the longest internode (6.85 cm). The maximum RLWC at irrigation scheduling at 0.3 bar (84.52%), 0.5 bar (79.15%) and 0.7 bar (75.34) was observed in 1103-P followed by Dogridge and Salt Creek. Based on the effect of the different irrigation regimes on grape rootstocks, the relative drought tolerance of grape rootstocks could be ranked as 1103-P > Dogridge > Salt Creek > 1613-C > 1616-C > SO4.
