| Abeliophyllum distichum Nakai (O1eaceae) is a monotype of Korea and is distinguished from related genus Forsythia Vahl by the morphological characters such as fruit shape, flower color and etc. Even though several intraspecific taxa were reported according to the color of flowers and shape of fruits, there have been many controversals on the taxonomic indentity and status of rank on those taxa. In the present study, we performed the RAPD analysis to delimit the infraspecific taxa of Abeliophyllum distichum and to investigate the genetic polymorphism and relationships among 12 populations. 212 scorable RAPD markers with 70 common markers were found from the PCR reactions with 16 random oligoprimers and were analyzed by Nei's genetic distance. From 0.108 to 0.321 of genetic variations were showed among the taxa. Some regional groups instead of same taxa were clustered from the phonogram of UPGMA analysis. Also, we could not find distinct lineage among intraspecific taxa. The result from RAPD analysis supported that the infraspecific taxa of Abeliophyllum distichum might be the individual variations and treated as the same taxa. RAPD analysis was very useful to confirm the high gene pool with diverse genetic polymorphism among Abeliophyllum distichum populations. |
