Post-harvest quality loss of sugarcane genotypes under sub-tropical climate : Deterioration of whole stalk and billets

  • Ishwar Singh

Post-harvest quality of five mid-late maturing sugarcane genotypes (CoLk 9606, CoLk 8102, CoLk 9617, CoS 767, CoPt 84212) was evaluated during late -crushing season. Sugarcane variety CoPt 84212 showed tolerance to post-harvest sugar losses as evident from lesser reduction in CCS percent, purity coefficient and increase in reducing sugars and dextran after 7 days of staling. On the other hand variety CoS 767 recorded high contents of dextran and reducing sugars with more purity drop and less recoverable sugar in stale canes alongwith higher acid invertase activity in this variety during post-harvest storage. Our study suggests that cane logistics especially during late-milling phase should be organized on the basis of sugar loss profile of cane varieties.
