SUMMARY
Hybrids were developed in a Line x Tester mating fashion on six females (lines) using four males (testers) to estimate the variability in quality traits in different environments. For this purpose, 24 specific cross combinations were developed by using these 10 diverse parents during kharif season in 2014-15. These hybrids along with 10 parents and two standard checks (SSG 59-3 and MFSH 4) were evaluated at two locations (Hisar and Karnal) with early and late sowing during kharif season in 201516. The analysis of variance indicated the presence of variability among hybrids and their parents. High and positive environmental index showed that E1 was the best environment for the expression of protein content, protein yield, in vitro dry matter digestibility, dry matter digestibility and HCN content. Hybrids 31A × IS 2389 recorded minimum HCN content (33.41 mg per kg green weight) followed by 9A × HJ G 46 (35.50 mg per kg green weight), 9A × HJ 541(38.18 mg per kg green weight). Other hybrids that showed low HCN content were 56A × IS 2389 (41.75 mg per kg green weight), 31A × HJ 513 (42.91 mg per kg green weight), 467A × G 46 (46.95 mg per kg green weight) and 9A × HJ 513 (47.92 mg per kg green weight)
Key words: Sorghum bicolor, environment, quantitative traits, green fodder yield and dry fodder yield
