An investigation was carried out to estimate genetic variability and interrelationship of characters in 225 sorghum germplasm under arid condition. Highly significant variations were recorded among 225 sorghum germplasm for all the traits studied. The phenotypic coefficients of variation (PCV) estimates were higher than the genotypic coefficients of variation (GCV) estimates for all the traits under investigation. The combined results for heritability showed that high estimates of heritability with high genetic advance and GCV were reported for panicle length, panicle width, fresh weight per plant and dry weight per plant indicating that these traits were under control of additive genetic effects. The fresh and dry weight per plant was strongly and positively associated with all the traits, except panicle width. The path coefficient analysis indicated positive and significant correlation as well as high, moderate or low direct effects of dry weight per plant, panicle length, stem diameter, days to flowering, leaf area, 1000 seed weight and grain yield per plant on fresh weight per plant. This indicates that effectiveness of selection for dual purpose sorghum as fodder cum grain crop could be enhanced by inclusion of leaf area, stem diameter, number of leaves per plant, panicle length and 1000 seed weight.
