Abstract:

Combining ability for yield and its components was analyzed in a 8×8 diallel crosses (excluding reciprocals), involving 3 indica and 5 tropical japonica rice. The GCA and SCA were significant for all the characters, indicating the importance of both additive and dominance genetic components. All the tropical japonica genotypes exhibited good general combining ability effects for yield and most of the yield contributing traits. The parents, IR 66155-2-1-1-2 for yield, 100 grain weight, number of spikelets per panicle, medium plant height and early flowering; IR 66159-23-2-2-1 for yield, number of spikelets per panicle, panicle length, flag leaf length and medium dwarf plant height and IR 65600-81-5-3-2 for yield, 100 grain weight, number of spikelets per panicle, flag leaf length and width were good general combiners. Among the crosses, Jaya×IR66738-118-1-2, Pant Dhan-12×IR66159-23-2-2-1, Pant Dhan-12×IR66155-2-1-1-2, Pant Dhan-12×IR66736-75-1-3 and Pant Dhan-12×IR66738-118-1-2 were good specific combiner for grain yield per plant.
