Studies on combining ability effects were executed through line x tester analysis under normal and saline sodic soil conditions. The results indicated the predominance of non-additive gene action for all the traits. The desirable lines, viz. NDB-1245, NDB-1445, NDB-3, NDB-1276, NDB-1302, K-762, K-880, HUB-202, BH-910, RD-2035, RD-2640, PL-820, PL-826, BCU-546, RD-2552 and four tester's, viz. NDB-1173, Azad, Lakhan, and NDB-943 were chosen for experiment. It was observed that the entries NDB-1245, NDB-1445 and RD-2552 were proved to be good general combiners for grain yield and quality component characters. The crosses namely, NDB-1302 x Aazd, RD-2035 x NDB-1173, RD-2640 x NDB-1173, K-762 x Azad and NDB-3 x NDB-1173 in normal soil and BCU-546 x NDB-1173, NDB-1302 x Azad, NDB-3 x NDB-1173, K-880 x NDB-943 and RD-2035 x NDB-1173 in saline sodic soil while NDB-1302 x Azad, RD-2035 x NDB-1173 and NDB-3 x NDB-1173 in both environments exhibited highest SCA effects for grain yield and a few quality traits, showing their desirability to offer transgressive segregants in succeeding generations.
