Abstract :

 The present study was conducted during 2014–15 to know the variation in growth and yield of eleven wine grape genotypes. The highest shoot length (75.34 cm) was recorded in Chenin Blanc at 60 days after back pruning. The maximum shoot girth (1.61cm) was recorded in Sauvignon Blanc at 105 days after pruning. The vigour of individual shoot increased with the decreased canes per vine. Chenin Blanc registered the maximum number of leaves per shoot (17.94) at 90 days after pruning and also Chenin Blanc had long period (20.00 days) for panicle emergence. The genotype Medika recorded the maximum length of berry (1.64 cm), diameter of berry (1.59 cm) and mean weight of berry (3.08 cm) at different intervals. The bunch length and weight of 50 berries varied significantly among the treatments. The maximum bunch length (23.33 cm) was found in Medika. However, Medika had the highest 50 berry weight (121.53 g) among the genotypes, Sirius was found to be an early where harvesting was done in 115 days. The maximum number of bunches per vine (110.44) was recorded in Grenache Blanc. The genotype Medika recorded the maximum bunch weight (419.15 g). However, the genotype Tempranillo registered the highest tonnage (60.88 t/ha) followed by Grenache Blanc (53.98 t/ha)
