abstract
In late Kharif 2021–22, a Randomized Block Design was employed to cultivate thirty-two genotypes of snake gourd for the purpose of assessing correlation coefficient and path coefficient analysis. The correlation coefficient analysis revealed a notable and positive correlation between various traits such as fruit yield per vine, number of fruits per vine, flesh thickness, fruit set percentage, fruit length, average fruit weight, number of female flowers per vine, number of seeds per fruit, and TSS at both phenotypic and genotypic levels. Path analysis further indicated significant positive direct effects at the genotypic level, particularly from node to first female flower, number of female flowers per vine, fruit set percentage, fruit girth, average fruit weight, number of seeds per fruit, and fibre content. At the phenotypic level, average fruit weight and number of fruits per vine also exhibited significant positive direct effects. Based on the comprehensive findings of this study, it was concluded that in the selection of superior genotypes, priority should be given to fruit yield per vine, followed by number of female flowers per vine, average fruit weight, and fruit set percentage.
