Study was carried out at Palampur and Bajaura in India.7 lines, 4 testers & their 28 hybrids were evaluated in RBD with 3 replications in line x tester mating design. ANOVA revealed significant differences among genotypes and GxE interactions, the line x tester analysis revealed significant differences due to line x location, tester x location & line x tester x location interactions (tested against error mean squares) at both locations and pooled analysis for most of the traits. GCA effects revealed that the lines BT-18 and Rodade and tester Hawaii-7998 and EC-392698 at Palampur;lines BL-333 and CLN-2123 and testers EC- 191536 and EC-392698 at Bajaura were good general combiners for yield and its contributing traits. However, BT-18 and BL-333 among lines and EC-392698 and Hawaii-7998 among testers were good general combiners for maximum traits studied in over all pooled analysis. Based on combing ability, heterosis and mean performance, crosses BT- 18xHawaii-7998, RodadexEC-392698 and BL-333xEC- 191536 in overall pooled analysis had great promise for further exploration. Preponderance of non additive gene action was fond in most of the traits.
