The study was undertaken to evaluate genetic variability, heritability and genetic advance as percent of mean among the 47 sorghum germplasm accessions for seven yield and yield attributes during 2015-16. 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, grain yield (kg/ha) and dry fodder yield (kg/ha) 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, plant height, grain yield (kg/ha) and 100-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.
