The combining ability was estimated for seven leaf related traits in five wheat genotypes under both irrigated and rainfed conditions. GCA, SCA, and reciprocal effects among parents and F1 were found to be significant for all traits studied. Most of the traits exhibited additive gene action except for leaf fresh weight, leaf water potential, and leaf osmotic potential in which maternal effects or extra nuclear genes inheritance was observed owing to higher reciprocal effects. Under rainfed environment, only leaf saturated weight, leaf dry weight, and leaf osmotic potential were under non additive control. V-04022 proved to be a good general combiner in both regimes for leaf area, leaf fresh weight, and leaf dry weight followed by V-04189 for leaf water potential and leaf turgor potential in canal irrigated conditions, and of PR-94 for leaf fresh weight and leaf saturated weight in rainfed conditions. Crosses combinations of V-03138 with the remaining parents showed highest SCA values for most of leaf traits, but PR-94×9247 exhibited as the best specific combiner for leaf fresh weight and leaf turgor potential under irrigated circumstances. PR-94 obtained 1st position for higher reciprocal effects for leaf saturated weight and leaf water potential in cross combination with V-04189, and for leaf area and leaf turgor potential with V-03138 in canal irrigation sown experiment. While under water scarce experiment 9247×V-04022 and 9247×V-04189 were at top for reciprocal effects for leaf fresh weight, leaf saturated weight, leaf water potential and leaf turgor potential, respectively.
