SUMMARY

Sorghum is widely grown as a semi-arid infallible fodder crop for livestock consumption. The availability of better quality green fodder for prolonged periods is directly associated with the lactation efficiency in animals which ultimately leads to the self sufficiency in milk production. The present investigation was conducted at Forage Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar during the Kharif season of 2019 for the estimation of amount of heterosis, heterobeltiosis and correlation between quality parameters of forage sorghum. The experimental material consisted of 18 F1 hybridsdeveloped by crossing three lines and six testers in L×T design. The crosses 9A × G 46 (-52.88%), 9A × HJ 541 (50%),14A × S 437 (-16.85%),9A × S 437 (-16.83%), 9A × S 437 (-16.99%), 9A × GFS 5 (-45.45%), 31A × G 46 (-64.56%, -68.53%) and SSG 59-3 (-42.57%) exhibited the high significant heterosis for sorghum quality parameters like crude protein,
total soluble solids (TSS),hydrocyanic acid (HCN), crude protein, neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose, lignin, tannin and phenol, respectively. The significant correlation observed between HCN, crude protein, NDF, ADF and cellulose contents indicating the scope of these crosses for the crop improvement. These findings can be applied to develop high heterotic hybrids with better forage quality for animal nutrition.

Key words: Hybrids, quality nutrition, correlation, heterosis, HCN, crude protein
