dc.description.abstractGenetic diversity for 20 isozymes of 13 enzyme systems and 8 morphological traits was determined in 348 accessions of grasspea (Lathyrus sativus L.) from 10 geographic regions. Accessions from the Near East were the most diverse, based on their high values for diversity index, number of allele per locus, observed heterozygosity and proportion of polymorphic loci; suggesting that grasspea originated in the Near East. Accessions from the Near East and North Africa had the lowest genetic distance, suggesting a common origin. Accessions from South Asia and Sudan-Ethiopia were genetically close even though these regions are widely separated geographically. Accessions from Southern Peninsular Europe and North America were genetically close, suggesting that most grasspea introductions into North America came from Southern Peninsular Europe. The large genetic distance between accessions from South America and those from other regions probably reflects a diverse origin of the few (2) accessions from that region.en_US
