The 40 fodder sorghum accessions were evaluated at Main Forage Research Station, A.A.U., Anand., during kharif season of the year 2011–2012. The experiment was laid out in randomized block design with three replication with different fifteen characters. The analysis of variance revealed significant differences among the genotypes for all the characters studied. This indicated the presence of sufficient variability in the experimental material. In the present study magnitude of genetic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), heritability and genetic advance as percentage of mean were recorded high for leaf: stem ratio, number of leaves per plant, green fodder yield per plant, stem girth and dry matter yield per plant. Therefore, more emphasis should be laid on these component traits, during selection programme for further improvement of green fodder yield per plant. High broad sense heritability estimates were recorded for most of traits viz., days to fifty per cent flowering, leaf: stem ratio, green fodder yield per plant, number of leaves per plant and dry matter yield per plant indicating that these traits were less influenced by the environment. These traits can be improved by simple selection procedure. Genetic advance as percentage of mean was observed high for leaf: stem ratio, dry matter yield per plant, green fodder yield per plant, number of leaves per plant and stem girth. It was moderate for number of tillers per plant, leaf width and dry matter content.
