Evaluation of genetic divergence for grain yield and its contributing traits in field pea (Pisum sativum L. var. arvense)

One hundred twenty genotypes of field pea were evaluated with four check varieties to assess genetic divergence for grain yield and its contributing traits. Significant differences among all the genotypes were recorded for all the characters studied except number of primary branches per plant. All the genotypes were grouped into twelve different nonoverlapping clusters by Non-hierarchical Euclidean cluster analysis on the basis of D2 values. The genotypes of cluster I had highest mean value (20.585g) for 100 seed weight.
