Genetic variability studies in bottle gourd (Lagenaria siceraria L.)

Abstract

The present investigation was carried out to estimate phenotypic and genotypic coefficient of variation, heritability (broad sense) and genetic advance per cent of mean for 14quantitative traits in 21 different genotypes of bottle gourd during Kharif 2018 at Instructional-Cum-Research Farm, Department of Horticulture, College of Agriculture Latur, Vasantrao Nike Marathwada Krishi Vidyapeeth (M.S.). Significant differences among the genotypes were observed for all the characters under study. The PCV and GCV values were high for vine length, number of branches per plant, sex ratio, fruit length, fruit diameter, fruit yield per plot, fruit yield per hectare, fruit yield per vine,. High heritability and high genetic advance were observed for characters like vine length, number of branches per plant, node at which first female flower appear, days required first female appear, number of male flower, sex ratio, fruit length, fruit diameter, fruit weight, fruit yield per vine, fruit yield per plot and fruit yield per hectare.
