Heterosis Studies for Grain Yield and Yield Components in Rabi Sorghum [Sorghum bicolor (L.) Moench.]

The present investigation was conducted to assess the magnitude of heterosis rabi sorghum (Sorghum bicolor (L.) Moench) developed by crossing four lines and twelve testers (in a line × tester design) produce 48 F1 cross combinations at Sorghum Improvement Project, MPKV., Rahuri, Maharashtra. To identify high-yielding Rabi hybrids, promising hybrids were sorted out based on positive significant standard for grain yield per plant. A total twenty-one exhibited best combination 104A x RSR 1012 (86.59%) maximum heterosis, followed X 1019 (73.17%) 104 1003 (70.73%) Heterosis has been considered well-proven method increasing improving traits in crops, exploitation hybrid development programme is one greatest breakthroughs plant breeding.
