Abstract
The shoot and root growth of nine grape rootstocks in terms of parameter was evaluated during the year 2024. The present investigation evaluated the performance of different grape rootstocks under semi-arid condition. T3 - 140Ru exhibited most promising features in terms of vigour and growth. It recorded the earliest bud sprout (10.76 days), highest success rate after 30 days of planting (87.78%), and the maximum survival percentage at 120 days (75.56%). In terms of vegetative traits, T3 - 140Ru recorded highest shoot length (25.16 cm), internodal length (3.70 cm), shoot diameter (3.37 mm). V.longii recorded the highest root length (2528.94 mm), T9 - 1613C had the maximum number of roots (60.00), and T2 - 110R showed the highest root diameter (1.82 mm). T3 - 140Ru exhibited the highest root volume (517.59 mm³).
