- Abstract
Investigation was carried out to determine combining ability and heterosis for yield and its component traits in rice. The material consisted of F1 hybrids of 30 crosses developed by crossing 10 lines with three testers. The cross HPR 2639 X HPR 2143 is good specific combination for grain yield/plant, panicle length, spikelets/panicle, grains/panicle, biological yield/plant, days to 50% flowering and plant height. Another hybrid, HPR 2529 X HPR 1156 also shows high heterosis over standard check for grain yield/plant biological yield/plant, grain fertility and plant height.
