Efficiency of selection based on genetic variability in Ridge gourd [ Luffa acutangula L. (Roxb.)]

Abstract

The present experiment was conducted at Main Experiment Station of Department of Vegetable Science at Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during 2015-16. The Analysis of variance, mean performance of genotypes, coefficient of variability, heritability and genetic advance in percent of mean were studies in 29 diverse genotypes of ridge gourd. Considerable variation was recorded for all the characters. The GCV and PCV estimate were high for node no. to anthesis of first staminate flower per plant followed by node no. to anthesis of first pistillate flower, days to anthesis of first staminate flower, days to anthesis of first pistillate flower, average fruit length (cm), days to anthesis of first pistillate flower, days to first fruit harvest, vine length(m), no. of nodes per vine, no. of primary branches per plant, average fruit diameter (cm), no. of fruit per plant, average fruit weight (g) and marketable fruit yields per plant (kg).
