Studies on genetic diversity in blackgram (Vigna mungo L. Hepper) genotypes

Abstract

30 Genotype of blackgram was evaluated in randomized block design was carried out to assess the analysis of variance, coefficient of variance, heritability, genetic advance, genetic advance as percent of mean using D2 analysis. The genotypes was grouped into six cluster. Cluster VIII consisted maximum accessions [8] followed by cluster I and cluster IV [7] and cluster V consisted [4] and cluster VI consisted [3] and cluster consist only accession. The inter cluster distance is greater than the intra cluster distance that considerable amount of genetic diversity existed among accessions. Maximum intra cluster distance was recorded for cluster IV (172.59) followed by, cluster V (148.37), cluster III (129.07) and cluster I (130.02) minimum for cluster V (25.12) and cluster VI (0.80). The character contributing maximum diversity towards in biological yield (16.32), plant height (16.02) cluster per plant (14.25), days to 50% (12.64) and seed per pod (9.89).
