Abstract

Genetic diversity in pea with 30 genotypes using D2 statistics revealed significant differences
among the genotypes for yield and its component characters. The genotypes were grouped into
4 clusters in E1, 4 clusters in E2, 5 clusters in E3, 5 clusters in E4, 4 clusters in E5, 5 clusters in
E6, 5 cluster in E7 and 5 cluster in E8. The intra cluster distance varied from 2.50(II) to 3.786
(III) in E1, 2.489 (II) to 3.409 in E2 (III), 2.546(V) to 3.065 (II) in E3, 2.494 (IV) to 3.282 (II)
in E4, 2.684 (III) to 3.020 (II) in E5, 2.667 (II) to 3.008 (IV) in E6, 0.000 (V) to 2.948 (I) in E7
and 0.000 (V) to 2.903 (III) in E8. The results revealed that clustering pattern of genotypes was
not consistence over environments. Number of clusters as well as number of genotypes in the
cluster differed from environment to environment
