Combining ability study for earliness and yield traits in rice for earliness and yield potential revealed non-additive gene action for these characters. Based on the per se performance and the gca effects, AD 95128 and AD 95134 were identified as superior parents for earliness. BTCE 23/99 and TKM 9 for yield potential and AD 95157 for both earliness and yield potential. The hybrid AD 95134 x IR 64 was the earliest for improving yield, AD 95157 x TKM 9 was identified as the best recombination for breeding.
