Genetic diversity and variability studies in moth bean [Vigna aconitifolia (Jacq.)]

Abstract

A field experiment entitled “Genetic diversity and variability studies in moth bean [Vigna aconitifolia (Jacq.)] was conducted at Agricultural Botany Research Farm, College of Agriculture, Pune during Kharif 2018. Thirty genotypes were obtained from Dry Land Agricultural Research Station, Solapur. The experiment carried out in randomized block design with three replications. Analysis of variance showed significant difference among genotypes for all characters. Phenotypic coefficient of variation was greater than genotypic coefficient of variation for all the characters showing higher influence of environment on characters. High heritability coupled with high genetic advance as per cent of mean was for the characters viz., clusters per branch, seed yield per plant, primary branches per plant, seeds per pod and secondary branches per plant and suggested that these characters are under the influence of additive gene action. Genetic diversity studies was carried out by using Mahalnobis D2 statistics which grouped 30 genotypes in 5 clusters. Cluster I having maximum genotypes followed by cluster II with 4 genotypes.
