A set of diallel crosses involving 10 diverse parents (excluding reciprocals) was made. Heterosis for grain yield per plant ranged from to per cent and to 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. | Heterosis and inbreeding depression studies for yield and its contributing traits in barley Hordeum vulgare L. under normal and late sown condition
