Abstract: To assess the extent of genetic variability and heritability of 12 genotypes and 4 standard checks of sweet sorghum (Sorghum bicolor (L.) Moench), the present experiment was conducted. The observations were recorded for 7 quantitative traits. The phenotypic co-efficient of variation (PCV) was greater than genotypic co-efficient of variation (GCV) for most of the characters studied indicating influence of the environmental effect on the characters. But the GCV values were close to PCV values for the characters like days to fifty per cent flowering, days to physiological maturity and grain yield, indicating very little effect of environment on the genotype, on the phenotypic expression for these traits. The genotypes under study showed high heritability for days to 50% flowering. High heritability combined with high genetic advance (as per cent of mean) was observed for grain yield, total biomass, days to 50% flowering, green cane weight. The correlation analysis indicating the days to 50% flowering. Days to physiological maturity showed significant positive association with plant height at 50% flowering and plant height at physiological maturity, while significant negative association was observed for grain yield...
