Ten parents along with forty-five hybrids (developed by half-diallel) and one check (Lok 1) were evaluated in RBD with three replications in three environments [early sowing (E1), normal sowing (E2) and late sowing (E3)] during rabi 2016-17. Simultaneous consideration of the mean, bi and S2di of the individual genotypes for grain yield per plant showed that among the parents, UP 2672 (22.18), DBW 110 (20.51), GW 451 (20.06) and Raj 4238 (19.29) recorded average grain yield per plant and average stability as the regression was not differing from unity and S2di also non-significant. Average yielding parent GW 451 (20.06) was also average responsive and stable for biological yield per plant and harvest index. Among five best crosses, cross GW 273 × Raj 4238 was average stable over environments. Similarly, three crosses viz., GW 463 × DBW 110, HD 2932 × Raj 4238 and GW 451 × HD 2932 favored for favourable environments.
