The present study on sugarcane cross derivatives involving ‘Co’ clones, it was found that specific combining ability was more important than general combining ability for number of millable canes (NMC), cane thickness and HR brix. The inbred 83 R 23 was the best general combiner for NMC, cane thickness and HR brix. Contribution of line × tester interaction to the total variance for NMC was the highest in testers (72.58%) followed by that of lines (32.98%). Among the testers, Co 775 was found to be a good combiner for NMC and Co 89003 for HR brix. Three crosses, viz., 83 R 23x Co 89003, 83 R 23x Co 775, and Co 98014x Co 89003 were the best specific combiners for NMC. Among the 15 crosses, the three crosses Co 7219x Co 775, Co C 671x Co 89003 and Co 98013x Co 89003 recorded significant and desirable heterosis for HR brix.
