Description Not Available
A study was conducted to determine the genotypic and
phenotypic variance and genetic diversity for yield and its
attributing traits in 56 germplasms of mungbean. Significant
variation among the landraces and genotypes was
recorded. Using cluster analysis by UPGMA method, all the
genotypes were grouped into 3 major and one minor
groups. Cluster I consisted 10 genotypes, cluster II 20,
Cluster III 24 and cluster IV 2 genotypes. The pattern of
distribution of genotypes from different locations into four
clusters was random, demonstrating that geographical
isolation may not be the only factor causing genetic
diversity. More emphasis should be given on cluster III for
selecting genotypes as parents for crossing with the
genotypes of cluster I. Principal component analysis
explained nearly 74% of total variation among genotypes.
By plot of first two components score for genotypes
confirmed the results of cluster analysis.
