Genetic Studies on Some Quantitative Characters of Rice in Diallel Crosses m. Differences of GCA and SCA Effects in $F_1$ and $F_2$ Generations

Degree of dominance for culm length, panicle numbers, flag leaf fwidth and panicle weight showed higher values than the others, and additive protions in variance components were more greater than heterosis protions for many characters. Average gene frequency showed low values for all characters, GCA were more greater than SCA, and the effects of GCA and SCA were differ from parents, crosses, generation and characters.
