To estimate combining ability and the model of gene action for some quantitative characters, 5 different rice genotypes were used for producing a half diallel hybrids. To consider 7 quantitative traits, hybrids and their corresponding parents were evaluated based on a randomized complete block design with three replications at the Rice Research Station of Amol, Iran in 2007. Mean squares regarding genotypes were statistically significant at 1% level of probability for all the studied traits. Significant general and specific combining abilities for all traits implied that additive and non-additive effects were effective in controlling these traits. Also, a non significant ratio for all characters except for 1000 grain weight expressed the greater importance of non-additive genetic effects rather than the additive ones for controlling the studied traits. Overall, parents Dasht, Neda and Binam were superior in general combining ability and hybrids Mashad Domsiah×Binam and Binam×IR6287-1-10 were the best for specific combining ability regarding yield and its components.
