The relationship between genetic similarity and larger geographical distance among populations of plant species has been attributed to a number of dif erent factors mostly breeding systems. We assessed this relationship among i ve accessions of seli ng legume Lathyrus sativus L. (grass peas, Fabaceae) using RAPDs by including 10 randomly selected individuals from each accession. Five primers produced 73 clear, reproducible and scorable polymorphic bands. The percentage polymorphic bands ranged from 20.6% in German to 60.3% in Polish accessions. The range of Nei’s within-accession genetic diversity was wide, ranging from 0.075 in German to 0.25 in Polish accessions. Partitioning of total genetic diversity by AMOVA indicated 76.44% genetic diversity among accessions and 23.56% within accessions, indicating that L. sativus is a seling species. The shortest genetic distance was detected between German and Iranian accessions (0.202), while the greatest genetic distance was revealed between Iranian and Polish accessions (0.5102), indicating that in seling species genetic similarity among accessions is not correlated with geographical distance.
