Abstract: Five pre release sugarcane clones viz., Co11001, Co11004, CoM11081, CoM11082 and CoM11084 in the early group were tested against the three standards Co85004, Co94008 and CoC 671 in two plant crops and one ratoon from 2016-17 to 2017-18. Based on their performance in the plant and ratoon crops, the clone CoM 11082 was found to be on par with the standards for cane and sugar yields. The clone CoM 11082 also recorded higher mean values for length of millable cane and single cane weight compared to other test clones. The clone CoM 11081 was found to be superior for juice quality over the other test clones but was on par with the standards The high yielding clone CoM 11082 may be recommended for commercial cultivation in Rayalaseema region after on testing in farmers’ fields. Number of millable canes, single cane weight, percent CCS and sucrose may be given due importance while for making selections for higher cane and sugar yields as the associations among themselves were positive and significant and also with CCS yield and cane yield.
