Genetic divergence studies in bottle gourd [lagenaria siceraria (mol.) standl.]

Abstract

An experiment was carried out to analyze genetic diversity for yield and its contributing traits in 31 bottle gourd genotypes at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), India; during Kharif 2014. The cluster analysis grouped all 31 bottle gourd genotypes into 5 major clusters based on D2 value. Extreme genetic divergence was estimated among clusters. Maximum number of genotypes were grouped into cluster V included ten genotypes, whereas, cluster II included eight genotypes. The cluster I had six genotypes, which is followed by cluster IV and cluster III had only three genotypes in each cluster. Fruit length, fruit girth and average fruit weight contributes maximum towards genetic divergence.
