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).
