Abstract

The genusLens includes 5 taxonomic species:L. culinaris is cultivated andL. orientalis, L. odemensis, L. ervoides, andL. nigricans are wild. All the species are annual and almost exlusively selfers. The wild lentils are distributed over a large geographical area and form small disjunct populations which are composed of a small number of plants. 67Lens populations were assayed electrophoretically for 9 enzyme systems; 15 enzymic genes with 37 alleles were identified. The genetic distances (D) measured between the pairs of populations indicated a significantly greater similarity between populations belonging to the same taxonomic species. Assuming the populations represent a random sample of the variability in each of the species the genetic distances (D) between the 5 taxa were calculated. The shortest genetic distance was found betweenL. orientalis andL. culinaris. Another significant feature of the data is the apparent isolation ofL. nigricans from the other 4 species. The genetic distances between theLens species are compared to the patterns of crossability barriers between them.
