Abstract:
The present experimentation was conducted to assess the genetic variability and heritability in 33 sweet sorghum genotypes at Sorghum Research Station, VNMKV, Parbhani during kharif 2019. Observations were recorded on eleven quantitative traits. The estimate of genotypic and phenotypic coefficient of variation were nearly equal in almost in all traits which indicates that the variability existing in these characters was due to genetic factors and there was less influence of environmental factor in the expression of these characters. High genotypic coefficient of variation was observed for juice yield followed by millable cane weight, grain yield, total fresh biomass and stem girth. Almost all the traits showed high estimate of heritability, however high heritability with high genetic advance was observed for juice yield, total fresh biomass, millable cane weight, grain yield, stem girth and juice extraction percentage indicating additive gene action and thus selection for these characters in genetically diverse material would be more effective for desired genetic improvement.
