The combining ability analysis from eleven parental lines in diallel cross in linseed (Linum usitatissimum L.) exhibited highly significant gca and sca effects from all the traits under study. This signified the importance of additive and non-additive gene effects in controlling the inheritance of characters. Parents, LC-185, Sweta and T-397 were identified as best general combiner for seed yield per plant. Twenty six cross combinations out of 55 showed significant and desirable sca effects for seed yield/plant. Best crosses on the basis of sca effects were Sweta x T 397, EC 41498 x1/76 , R-17x1/76, N- 3 x T-397 and J- 23 x LC 185.
