Abstract

Observations were recorded on flowering and bearing habits of six grape cultivars grown at Instructional-CumResearch Orchard, Department of Horticulture, M.P.K.V., Rahuri, Dist. Ahmednagar. For bud-burst after October pruning, Bangalore Purple and Rubi Red required minimum days (12 and 13, respectively) and Hur the maximum. (22 days).Thomson Seedless, Muscat and Pandhuri Sahebi were in between. Cane sprouting was maximum in Bangalore Purple (92.89%) followed by Rubi Red (81.37%). It was minimum in Muscat (44.25%). A great variation was noticed in percentage of fruitful canes and fruitful shoots.The highest percentage (97.87%) of fruitful canes was in Rubi Red and the lowest (23.21%) in Flur.The fruitful shoots also varied from 17.65 per cent in Hur to 95.65 per cent in Rubi Red. Mostly one to two panicles were produced on a shoot. In Thomson Seedless and Hur more than 90 per cent of productive shoots produced only one panicle. However, in Bangalore purple, 66.5 per cent of the productive shoots had two panicles each.The duration of flowering was maximum in Pandhari Saheb' (30 d) and minimum in Bangalore purple (16 d).
