Impact Studies on Delayed Crush on Post-Harvest Deterioration of Promising Sugarcane Clones

The present study was conducted with five promising early maturing sugarcane clones at Regional Agricultural Research Station, Rudrur [latitude of 18o-300' north and 77o-510' longitude to the east at an elevation of 404 m above mean sea level], Nizamabad district, T.S., India during Rabi 2014-15. The key objective of the present investigation was to study the impact of a delayed crush on postharvest deterioration of promising sugar cane clones. Different biochemical aspects like percent juice sucrose, commercial cane sugar percent, juice extraction percent and reducing sugars % were assayed from 0-72 h. The results of the study indicated that the clones such as Co 99004 and 2011 R 42 indicated the highest sucrose percent (22.29% & 20.87%) and CCS percent (15.84% & 14.87%) respectively, percent reduction in single cane weight of Co 99004 and 2010 R 305 (1.83 and 1.63) and juice extraction percent of clones 2010 R 305 & 2011 R1 were 55 & 53 percents respectively. Among the five clones tested 2010 R 305 maintained its cane quality up to 72 hours with minimum percent reduction of 4.05, 4.30, 2.80 and 4.25 for to sucrose content, CCS percent, juice extraction percent and percent reduction in single cane weight, respectively followed by 2011 R 1 and Co 99004. The Present study concluded that 2010 R 305 was found to possess tolerance to Post- harvest deterioration.
