Heterotic expression and combining ability was studied for fifteen yield and related traits in maize involving 66 F1 crosses produced in line x tester design. Pooled analysis of variance revealed significant differences among lines, testers and line x tester crosses except for leaves per plant and ear girth due to testers. Inbred lines L9. L13, L14, L15 and L18 were good general combiners for earliness; L2, L3 and L5 for higher plant height, ear height and number of leaves per plant, L2 and L3 for ear length, ear girth, kernel rows ear, kernels per row, 100 kernels weight, grain yield per plant, dry stover yield per plant and biological yield per plant. On the basis of SCA and
