Popis:	Allopolyploid vs. autopolyploid origins of polyploid species of the genus Lathyrus have been tested by the C-banding technique and electrophoretical procedures for 11 genetic loci belonging to six isozyme systems. Results of both experiments suggest for the polyploid populations of L. palustris and L. pratensis an autopolyploid origin from their respective diploid counterparts. Nevertheless, L. venosus seems to have originated through allopolyploidy involving two sympatric diploid species, L. ochroleucus and L. palustris.
