Variability, correlation and path coefficients were studied in four lines of bottle gourd. Genotypic and phenotypic variability were high for fruit length and number of branches per plant, but very low for number of fruits per plant and length of main vine. Heritability (broad sense) and genetic advance in percentage of mean were high for fruit length, fruit diameter and fruit weight per plant. Fruit weight per plant had strong positive genotypic correlation with days to first picking, length of main vine and fruit diameter and a negative correlation with fruit length. Path coefficient analysis revealed that fruit diameter and fruit length had high positive direct effect on fruit weight per plant. Number of fruits per plant also had considerable positive direct effect on fruit weight per plant.
