Path coefficients were computed to assess the direct and indirect influences of 16 characters on seed size (or 100-seed weight) in 52 exotic sorghum genotypes grown in the two consecutive kharif seasons of 1988-89 and 1989-90. Path analysis revealed the highest positive indirect effect of 100-seed volume (or seed heaviness) followed by gross panicle weight, plant height, threshing percentage and days to 50% flowering on seed size.
