Abstract:
Sponge gourd [Luffa cylindrica (L.) Roem.] is an important vegetable crop having chromosomes (2n=26). It is an annual climbing plant with cross pollinated nature. It is difficult to assign with accuracy the indigenous area of Luffa species. Sponge gourd is an annual climber and monoecious vegetable. There is wide variability in size of fruit; ranging from a few centimeters to one meter, fruit shape and colour as traits are complex and controlled by several genes. The experiment conducted on 15 genotypes of sponge gourd was subjected to evaluate parameters of variability, correlation and path analysis for fruit yield and its attributing traits. Significant variations were observed for all the character in all the genotypes used in the experiment. The analysis of variance revealed that mean sum of squares due to genotypes was highly significant for all characters except days to first fruit harvest. Highest genotypic and phenotypic variation were observed for fruit yield q/ha followed by fruit length, fruit yield per plot, vine length, number of fruit per plant and average fruit weight. The fruit yield q/ha followed by fruit yield per plot, number of fruit per plant, average fruit weight, days to 1st fruit harvest, fruit girth and fruit length showed high heritability coupled with high genetic advance. Hence, selection for these traits for improving fruit yield per plot in sponge gourd is suggested.
