The analysis correlation and path coefficient for yield and yield atributes was investigation at Regional Horticulture Research and Extension Centre (RHREC), Dharwad, university of Horticultural Sciences, Bagalkote (Karantaka) during the year 2022-2023 with twenty-eight genotypes of sponge gourd (Luffa cylindrica L. Roem.) laying in two replications in Randomized Complete Block Design (RCBD). Significant amount of variation was observed for all the attributes in the genotypes in the experiment. Correlation revealed number of fruit per vine had a significant and positive correlation with vine length at 90 DAT, number of primary branches at 90 DAT, average fruit weight, fruit length and fruit diameter. It was observed that with increase in vine length, there is corresponding increase in number of primary branches at 90 DAT, average fruit weight, fruit length and fruit diameter. Path coefficient analysis for yield and yield contributing traits on number of fruit per vine exhibited positive direct and indirect effect on vine length at 90 DAT, number of primary branches at 90 DAT, days to first female flower appears, fruit length, fruit diameter and average fruit weight as these characters play a major role in recombination breeding and suggested that direct selection based on these traits will be beneficial for crop improvement of Sponge gourd
Sponge gourd, genotypes, correlation, path analysis, traits
Correlation reveled that number of fruit per vine had a significant and positive correlation with vine length at 90 DAT, number of primary branches at 90 DAT, average fruit weight, fruit length and fruit diameter while the negative and significant correlation were noted in node at which first male flower appears, node at which first female flower appears, days to first male flower appears, days to first female, and days to first harvest at both genotypic and phenotypic level. This implies that improvement of these traits simultaneously is impractical and is complex. But can be exploited for developing yield and yield attributes. Path coefficient analysis depicts that characters like vine length at 90 DAT, number of primary branches at 90 DAT, node at which first male flower appears, node at which first female flower appears, days to first male flower appears, days to first female flower appears, days to first harvest, fruit length, fruit diameter, average fruit weight, number of fruit per vine can be comprised for improve of fruit yield per vine since, these reflect positive direct and indirect effect and can be consider further for crop development in Sponge gourd
