An experiment was conducted with 60 genotypes of pumpkins to study the correlation and direct and indirect effects of different characters on fruit yield per hectare. The experiment was conducted in a randomized block design. Correlation studies indicated that fruit yield per hectare was positively and significantly correlated with fruit yield per vine (0.991, 0.980), average fruit weight (0.718, 0.686), number of fruits per vine (0.524, 0.555), fruit flesh thickness (0.500, 0.406), fruit width (0.483, 0.436) and fruit length (0.464, 0.419) at both genotypic and phenotypic levels. Genotypic path analysis shows that days to first male (1.0918) and female (-0.7358) flowering, fruit length (-0.6348), average fruit weight (0.5923), number of fruits per vine (0.4736) and fruit yield per vine (0.4645). Therefore, emphasis should be given on days to first male and female flowering, fruit length, average fruit weight, number of fruits per vine and fruit yield per vine for enhancing the yield of pumpkin
