Abstract

Thirty one advanced genotypes of pea involving six varieties + 25 promising genotypes were evaluated for assessing genetic divergence for grain yield. Significant differences among the genotypes were recorded for all the characters studied. Genotypes were grouped in six clusters based on D2 values. Cluster Ist was more divergent and monogenotypic involving advance genotype KPMR632. Cluster VIth was the largest with eight genotypes. The inter cluster distance was minimum (12.04) between cluster IIIrd and VIth and maximum (41.35) between couster Ist and IInd closely followed by Ist and IVth. The intermating among genotypes following clusters Ist, IInd and IIIrd would be of breeding value so as to improving grain yield.
