The current investigation was undertaken at the experimental plot of Department of Vegetable Science, College of Horticulture, UHS, Bagalkot (Karnataka) during 2020-2021. Fourty sponge gourd genotypes collected from different places were evaluated to know the character association between them. The correlation coefficient analysis measures the mutual relationship between various plant characters and determines the component characters on which selection can be based for improvement in yield. The present study indicated that genotypic correlation co-efficient is higher than the phenotypic correlation co-efficient for all the 17 characters studied. This indicates very little or no influence of environment on genotypes performance and the presence of inherent association between various characters. The trait fruit yield per vine was significantly and positively correlated with vine length, number of branches per vine, fruit length, average fruit weight and number of fruits per vine and sponge yield at both genotypic and phenotypic levels. Therefore, selection based on these characters can be effective for identifying high yielding sponge gourd genotypes.
Sponge gourd, fruit yield, phenotypic and genotypic correlation co-efficient
The present investigation revealed that fruit yield per vine was significantly and positively correlated with vine length, number of branches per vine, fruit length, average fruit weight and number of fruits per vine and sponge yield at both genotypic and phenotypic levels. These traits were considered as important component contributing to fruit yield per plant and the selection primarily based on these characters may result in development of high yielding genotypes.
