Abstract: Fifty genotypes of Sudan grass were evaluated in a randomized block design with three replications to estimate variability, correlation and path analysis. High heritability estimates were observed for all the characters studied, except L: S ratio. High estimates of heritability (b.s) accompanied by high genetic advance as percentage of means was reported for characters viz., days to 50% flowering, green forage yield, dry matter yield, plant height, crude protein yield, number of tillers, stem thickness, leaf width, crude protein content and leaf length. Correlations studies showed that green forage yield was significantly and positively associated with plant height, number of tillers, leaf length, stem thickness, dry matter yield and crude protein yield. Path analysis revealed that leaf width exhibited highest positive direct effect on green forage yield as well as it showed significant and positive correlation with green forage yield. Stem thickness showed highest negative direct effects on green forage yield which was followed by leaf: stem ratio, plant height, leaf length, crude protein content and dry matter yield. The pair of genotypes viz., IS-700 and cofs-29 (D2= 1523.39) was most divergent from one another and genotypes like, IS-3236, IS-3284, IS-700 and cofs-29 for improvement in green forage yield of Sudan grass.
