Abstract

An investigation was undertaken to study the pattern of sucrose accumulation in five sugarcane varieties especially under delayed harvest. It was evident that maximum sugar accumulation occurred during 12th month irrespective of varieties. In general, the quality declined with advance in age. There was a mean reduction of 3.55% in quality by three months delay in harvest. Among the five varieties studied, sugar sustainability could be seen.in Si 86098 which recorded the highest CCS of 10.57% even at the age of 15th month. The present investigation led to the identification of cane clones for sugar sustainability even under delayed harvest. Such clones can be maintained and utilised for its sugar retention as donor.
