Abstract

A set of 65 sugarcane clones representing hybrid germplasm was evaluated for genetic variation, mean performance and character association. There was a large variation for canc yield brought about jointly by cane number, cane diameter and cane height. Variation for sucrose on the other hand was relatively low. Three clones, Co 7008, CoC 671 and Q 63 were found to be high sucrose types recording more than 20% sucrose at 12th month. Co 678, Co 62175, H 49-3533 and Co 7201 were found to possess high yield potential. Cane yield was positively associated with leaf area, internode number, internode length and cane diameter. Association of cane yield with cane number, on the other hand, was not significant. The association between cane yield and sucrose, although not significant, showed a negative trend, when very high yielders and very high sucrose type were considered.
