General and specific combining ability of five fertile male (lines) and two male sterile (tester) of rice were evaluated for 10 important morphological traits as well as yield and yield components in a randomized complete block design with three replications. Results revealed that general combining ability effects were highly significant (P<0.05) for yield, 100 grain weight and fertility percentage traits. But, specific combining ability was significant (P<0.05) only for yield and tiller number traits. Genotypes with good general combining ability like Bejar and IR28 can be used in inbred breeding program. While, crosses with high specific combining ability such as 6 X 1 and 4 X 7 can be used in hybrid cultivar production.
