An experiment was conducted to evaluate the performance of 54 F1 developed by crossing of 18 lines with 3 testers. Analysis of variance revealed highly significant difference in treatments, parents, crosses and line × tester for days to 50% flowering, plant height, flag leaf area and grain yield per plant under both normal and saline conditions. Parent vs. crosses were highly significant for plant height and grain yield per plant while significant for days to 50% flowering and flag leaf area in normal condition but in case of saline condition highly significant differences were found for plant height and flag leaf area and non-significant for days to 50% flowering and grain yield per plant. Analysis of variance revealed highly significant differences among lines for grain yield per plant under both normal and saline conditions while plant height for saline condition. Tester was non-significant for all the characters under both normal and saline conditions. The estimates of variance of specific combining ability effects, ratio of variance of general combining ability to specific combining ability and degree of dominance indicated preponderance of non-additive gene effects for each trait. On over all bases, role of lines in the expression of most of the morphological traits were more than testers and line × tester interaction under both conditions.
