A set of diallel crosses involving 10 diverse parents (excluding reciprocals) was made. Heterosis for grain yield per plant ranged from -21.95 to 39.65 per cent and -48.13 to 64.34 per cent under normal and late sown conditions, respectively. Out of 45 crosses fifteen crosses in both the sowing conditions exhibited positive significant heterosis while, nine crosses in normal and seven crosses in late sown condition exhibited positive significant heterobeltiosis. In both the environments the crosses BHS 400 × PL 426, BHS 400 x BHS 380, BG 105 x BH 959, PL 426 × RD 2552 and BH 959 × RD 2552 exhibited positive significant heterosis and heterobeltiosis while out of only one cross 426 × RD 2552 has desirable negative significant inbreeding depression. Hence, these crosses were considered to be most desirable for grain yield per plant. The study revealed good scope for commercial exploitation of heterosis as well as isolation of pure lines among the progenies of heterotic F1 for improvement of yield levels in barley.
