| Random amplified polymorphic DNA(RAPD) markers were investigated to clarify the taxonomic positions of Vicia linearifolia and V. bifolia, and to assess the genomic diversity among the 9 populations of V. unijuga, each of which represents a geographical variation or infraspecific taxa in southern Korea. These species are characterized by unijugate leaves in East Asia and have been controversial as to infra- or interspecific classification. The polymorphic markers among the populations examined were observed for fifteen decamer primers. The degree of band sharing was used to calculate genetic similarity between populations, and a phenogram using UPGMA cluster analysis was generated based on the Dice similarity coefficient. The taxa studied were divided into two main groups and the populations of V. unijuga were all grouped together in the phenogram. The genetic similarities of V. unijuga were very high among the populations and did not show distinctions between the infraspecific taxa, although the populations of Mt. Odae and adjacent areas in eastern Korea wre different from others of the species. V. linearifolia fell within the range of the genonmic variation among the populations of V. unijuga, while V. bifolia was grouped with V. venosa var. cuspidata having multijugate leaves rather than V. unijuga. The result from studying RAPD markers suggested that V. linearifolia should be integrated into V. unijuga and that species with unijugate leaves of V. bifolia and V. unijuga are polyphyletic. |
