Abstract: The investigation was carried out during the fruit pruning season 2022-23 on 6-year-old vine of Crimson Seedless at ICAR- National Research Centre for Grapes, Pune. The vines were grafted on four different rootstocks (Dogridge, 110R, 140Ru and 1103P). The vines grafted on Dogridge rootstock recorded high TSS, lowest acidity and high TSS: Acidity ratio. 110R rootstocks had lowest berry firmness and skin thickness. 110R rootstock showed better results in organoleptic quality such as color, sweetness, taste, mouthfeel, flavor and overall acceptability as compared to other rootstocks. Rootstocks 110R recorded lowest rate of rachis dehydration and minimum physiological weight loss from bunches on different days of the shelf life. The vine grafted on Dogridge and 140Ru grafted vines recorded least rotten berries while 140Ru had the lowest number of fallen berries during shelf life. In conclusion, Crimson Seedless vines on 110R rootstock enhance shelf life and sensory quality of grapes, but terms of fresh grape quality Dogridge show better results.
