Studies on genetic variability for yield and yield contributing traits in Colored pericarp sorghum (Sorghum bicolor (L.) Moench)

Genetic variability in any crop is pre-requisite for selection of superior genotypes over the existing cultivars. Knowledge of variability and heritability of yield and its contributing traits helps in the selection of appropriate strategy for a breeding programme for evolving superior varieties. Therefore, the present investigation was conducted to assess the variability present in colored pericarp sorghum for yield and yield contributing traits. In present study, analysis of variance shows that there is considerable difference between the genotypes for all the traits. The result of genetic parameters revealed that moderate to high PCV, GCV, high heritability accompanied with high genetic advance was recorded for all the traits except days to 50% flowering, days to physiological maturity, 100-seed weight, threshability this suggesting that the selection would be efficient for these characters to bring genetic enhancement in desired way.
