The study on genetic variability, correlation and path analysis in F6 generation of ridge gourd (Luffa acutangla (Roxb) L.) for yield and quality was conducted at College Orchard, Department of Horticulture, Agricultural College and Research Institute, Madurai during the year 2019-2020. The aim of the present study is to develop high yielding, medium size fruit and good quality fruits of ridge gourd. The 11 selected ridge gourd accessions derived from two crosses viz., Virudhunagar local x Periyakottai local (L3 x T1) and Virudhunagar local x Alathur local (L3 x T2) along with checks used for this study. The present study was laid out in Randomized Block design (RBD) with three replications. The results revealed that moderate GCV, PCV and high heritability along with high genetic advance as percentage of mean recorded for the character fruit length (13.14 %, 14.06 % and 87.44 %, 25.32 %). Whereas low GCV, PCV and low heritability along with low genetic advance was recorded for the characters node to first female flowering (3.62 %, 8.28 % and 19.15 %, 3.26 %) and rind thickness (5.21 %, 9.93 % and 22.74 %, 5.12 %). Regarding correlation studies, fruit yield was significantly and positively correlated with fruit weight and sex ratio. In the present study, path coefficient analysis showed that positive direct effect on vine length, days to first harvest, fruit weight, fruit length, rind thickness and number of fruits per plant. Of these traits, fruit weight exhibited the maximum positive direct effect on yield.
