Promising sugarcane clones 2006A 102, 2001A 63, 2007A 161, 2007A 223, 2001A 70, 2001A 109, 2007A 64, 2006A 81, 2006A 22, 2006A 130, 2006A 107 and Co 6907 (C) were studied for juice quality parameters at different months of crop age (12th and 13th months) and at different intervals of harvest at Regional Agricultural Research Station, Anakapalle, during 2013 – 14 and 2014 – 15. Decline in per cent juice sucrose was observed high at 13th months (March) of crop age in all varieties and its rate of decline was low in 2001A 63, 2006A 22, 2007A 109, 2007A 223 and 2006A 22. Reduction in per cent sucrose was noticed high in 13th month (March) of crop age. Per cent reducing sugars were high at 72 hours after cane harvest. All the tested varieties loss their cane weight at 72 hours after cane harvest but their rate of loss was low in sugarcane clones 2001A 63, 2007A 223, 2001A 70 and 2006A 22. Based on per cent juice sucrose reducing sugars, Dextran (ppm), and cane weight loss at different months of crop age and at different intervals of crushing after harvest. Sugarcane clones 2001A 63, 2007A 223, 2001A 70 and 2006A 22 were found to be competitively more tolerant to post harvest deterioration.

Key words: Cane quality deterioration, sucrose per cent, Reducing sugars, Dextran (ppm).
