SUMMARY

The present study was conducted to evaluate the promising forage sorghum [Sorghum bicolor (L.) Moench] genotypes superior in quality and yield. The experiment was carried out in Forage Section, Department of Genetics & Plant Breeding, CCS HAU, Hisar in a randomized block design with three replications. The observations recorded were HCN, IVDMD, crude protein content, structural carbohydrates and green fodder yield. Minimum HCN content was estimated in SPV 2455 (23µg/g) followed by SPV 2449 (64µg/g). Crude protein content was highest in SPV 2446 (10.94 %) followed by SPV 2447 (10.72 %) and IVDMD was maximum in SPV 2448 (50.80 %) followed by SPV 2450 (50.40 %). Among structural carbohydrates, highest NDF content was observed in CSH 13 (63.87), ADF content in SPV 2455 (39.55), cellulose in SPV 2449 (38.90) and hemi-cellulose in SPV 2455 (29.87) on percent dry weight basis. In terms of green fodder yield, the genotypes SPV 2444 (395.5 q/ha) and SPV 2454 (374.0 q/ha) were found superior.
