Determining relationships between different Horticultural and Yield Traits in sponge gourd (Luffa cylindrica Roem.) Genotypes with path coefficient analysis

Abstract

The aim of experiment was to study the inter-relationship and direct-indirect effect among yield and yield attributes in sponge gourd. The analysis of variance revealed that the mean sum of squares due to genotypes were significant for all the eleven traits. The genotypic correlation in general was greater than the phenotypic correlation. The significant and positive correlation with yield per plant was observed at phenotypic level with average fruit weight (0.462) and number of fruits per plant (0.476). Path coefficient revealed appreciable amount of direct positive effect of number of fruit per plant (0.653) followed by average fruit weight (0.571) and days to anthesis of firs pistillate flower (0.156) on fruit yield per plant. The study concluded that the average fruit weight and number of fruits per plant in due consideration for improvement of genotypes in respect to yield.
