Evaluation of coloured seedless table grape varieties for increase in shelf life

An experiment to study the shelf life of four table grape varieties was conducted at National Research Centre for Grapes, Pune (M.S.). Grape bunches packing and the cold storage condition for 30 days after precooling for 24 hours was according to the export standard. After cold storage, shelf life and other quality parameters were recorded for four days. Lowest physiological loss of weight was recorded in Sharad Seedless followed by Mahadev Seedless. These two varieties also performed better for the quality parameters in terms of bunch weight, 5 berry weight and berry diameter which are favourable for better shelf life. Significant differences were found for the quality parameters except total soluble solids (TSS). Overall, Sharad Seedless and Mahadev Seedless recorded with the lowest per cent of berry fallen and rotting among the four varieties studied.
