Description A study was conducted during 2006–07 to assess the genetic divergence available in fieldpea (Pisum sativum L.) germplasm, based on Euclidean distances for the identification of genetically diverse and agronomically superior accessions which may generate putative transgressive segregates on hybridization. Based on the results obtained in field experiments, designed in Augmented one, wide morphological divergence were obtained for all the traits under study. Principal component analysis, which transformed all the metric traits into single index of similarity, yielded 8 eigen vector and roots. Based on first 4 principal components (which accounted for 86.51% of the total variation), nonhierarchical Euclidean cluster analysis grouped the 480 fieldpea accessions into 8 well characterized groups (based on aggregate effect of similarity in traits). There is no parallelism between genetic diversity and geographical origin of accessions.
