Forty six diverse genotypes evaluated to study the genetic variability heritability and genetic advance in sorghum. All the genotypes showed significant and considerable amount of variation in their mean performances with respect to the characters studied indicates presence of sufficient variability and scope for further selection and breeding superior and desirable genotypes. Phenotypic variance was higher than genotypic variance for all the traits which indicate the performance of individual not only due to genotype but also in some proportion by environment. GCV played a major role for the expression of the traits. Grain yield per plant had high GCV followed by fodder yield per plant and panicle length. High heritability coupled with high genetic advance was recorded for grain yield per plant, fodder yield per plant, panicle length, panicle weight and stem girth. It was moderate for days to maturity, days to 50% flowering; leaf length and leaf width revealing that characters are governed by additive gene action and phenotypic selection for these characters will be effective.
