The present investigation was carried out during the 2024-2025 growing season at the Vegetable Research Farm, Department of Horticulture, SHUATS, Prayagraj, with the objective of assessing the correlation and path coefficient analysis in ridge gourd (Luffa acutangula L.). A total of ten diverse genotypes were evaluated using a randomized block design (RBD) with three replications to ensure precision and minimize environmental variation. Correlation analysis revealed a highly significant positive genotypic association between fruit yield per plant and days to first harvest (rg = 0.8696**), as well as a moderately significant positive correlation with days to first male flower (rg = 0.5741*, rp = 0.4148*). Conversely, a significant negative correlation was observed between average fruit weight and fruit yield per plant (rg = -0.6455*, rp = -0.5315**), indicating an inverse relationship. Genotypic correlations were generally stronger than phenotypic ones, indicating a predominant genetic influence, with environmental factors partially masking these relationships at the phenotypic level. Path analysis revealed that days to first female flower, days to first and last harvest, fruit weight, fruit diameter, and fruit length had direct positive effects on yield, making them important traits for selection.
