Genetic divergence in advanced genotypes for grain yield in field pea (Pisum sativum L.)

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 I^st was more divergent and monogenotypic involving advance genotype KPMR632. Cluster VI^th was the largest with eight genotypes. The inter cluster distance was minimum (12.04) between cluster III^rd and VI^th and maximum (41.35) between couster I^st and II^nd closely followed by I^st and IV^th. The intermating among genotypes following clusters I^st, II^nd and III^rd would be of breeding value so as to improving grain yield.
