Abstract: The study was undertaken to evaluate genetic variability, heritability and genetic advance as percent of mean among the 60 sorghum germplasm accessions along with four checks for 14 yield and quality characters. The values of PCV were observed higher than the values of GCV for all the traits, indicating the environmental influence on the expression of these characters. High values of PCV and GCV were noted for plant height, 1000-seed weight, ear head length, harvest index, crude fibre content, total antioxidant activity, dry fodder yield, total phenol content and grain yield per plant, implying high degree of variability in these traits among the genotypes under study. High heritability in addition to high GAM was observed for the traits viz., ear head length, total phenol content, dry fodder yield, days to maturity, plant height, water absorption capacity, protein content, harvest index, grain yield per plant, crude fibre content, days to 50% flowering, total antioxidant activity and 1000-seed weight, suggesting the functioning of additive gene action in the inheritance of these traits. Therefore, simple phenotypic selection is sufficient for improving these traits.
