Variability and path coefficient analysis were carried out in 170 germplasm lines of sorghum. The study revealed high estimates of genotypic coefficient of variation (GCV), heritability and genetic gain for plant height, stover yield, leaf area, flag leaf area, peduncle length and harvest index. Grain yield/plant showed positive and significant association with plant height, flag leaf area, panicle weight, panicle girth, number of primaries and whorls of primaries per panicle. Characters like panicle weight, panicle girth and days to 50% flowering revealed higher positive direct effect on grain yield in path coefficient analysis.
