The present investigation on genetic variability, correlation and path analysis of F5 generations of ridge gourd was carried out at College Orchard, Department of Horticulture, Agricultural College and Research Institute, Madurai, Tamil Nadu during 2018 – 2019 to develop medium size, high yielding and good quality variety suitable for Madurai condition was aimed at. The selected genotypes from the two crosses viz., Virudhunagar local x Periyakottai local (L3xT1) and Virudhunagar local x Alathur local (L3xT2) of ridge gourd along with their parents were evaluated. This study was laid out in a randomized block design (RBD) with two replications. The results revealed that both the crosses showed low PCV, GCV coupled with high heritability and high genetic advance for the character node to first male flower. Whereas low PCV, GCV coupled with high heritability and low genetic advance for the characters vine length, days to first female flower and sex ratio. Regarding correlation studies revealed that cross L3xT1 the trait fruit yield was found to be significantly and positively correlated with node to first male flower, node to first female flower, days to first harvest, fruit weight, number of fruits per plant and flesh thickness. Whereas cross L3xT2, fruit yield was found to be significantly and positively correlated with node to first male flower, node to first female flower, fruit weight, fruit length and fruit diameter. Path coefficient analysis showed that fruit weight in L3xT1 cross has contributed the maximum positive direct effect whereas cross L3xT2 fruit diameter contributed the maximum positive direct effect in F5 generation.
