Abstract:
The present experiment was carried out thirty six cucumber genotypes under Randomized Block Design with two replications to assess the PCV, GCV, heritability and genetic gain for various horticultural traits. In this study phenotypic coefficient of variation (PCV) were higher than the corresponding values of genotypic coefficient of variation (GCV) while the difference between PCV and GCV was very less for length of vine, number of primary branches, number of nodes per vine, node number bearing first male flower, node number bearing first female flower, days for first male flower, days for first female flower, days for first harvest, number of male flower, number of female flower, number of fruits per plant, fruit length, fruit diameter, fruit weight and yield per plant and these traits are less influenced by environment. High phenotypic and genotypic coefficient of variation were observed number of primary branches, node number bearing first male flower, number of male flower, number of female flower, number of fruits per plant, fruit length, fruit weight and yield per plant. In this experiment all the studied traits had high heritability coupled with high to moderate genetic advance except days for first male and female flower appearance.
