One hundred and seventy-five genotypes of pop sorghum of diverse origin were used to estimate genetic variability and correlation for 13 characters. The characters viz., fodder yield per plant, grain yield per plant, flake size, expansion ratio and popping yield exhibited high phenotypic coefficient of variability, genotypic coefficient of variability, heritability and genetic advance. Correlation studies indicated that grain yield per plant was found to be significantly and positively associated with panicle weight, fodder yield per plant, while expansion ratio and flake size with popping yield. The positive correlation observed among days to 50 per cent flowering, plant height, number of leaves, panicle weight, number of primaries and fodder yield per plant indicated that grain yield is largely a function of these five attributes. Similarly, the positive correlation observed among flake size and expansion ratio indicates that popping yield is largely a function of these two attributes.
