Abstract: The present investigation was conducted to assess the genetic variability among 24 genotypes collected from different institute/SAUs during kharif season (2018-2019). Genotypic correlation coefficient were found to higher than phenotypic correlation coefficients for most of the characters, indicating a strong inherent association between various characters and significantly affected by environmental components in regard to phenotypic expression. Based on correlation coefficient, fruit yield per plant showed positive and highly significant correlation with number of fruit per plant, days to first fruit set at both genotypic and phenotypic level, which implies that these characters were the primer contributing factors to fruit yield. Path coefficient analysis showed highest positive direct effect on fruit yield was observed for fruit weight, days to first fruit set, fruit girth and fruit length. By improving other characters fruit yield in bottle gourd might be improved.
