Abstract: The genetic variation and genetic relationships among 24 samples of Platycodon grandiflorum DC. cultivars collected from East-Asian area (China, Japan, Korea and DPRK)were analyzed by the method of RAPD-PCR markers. The results showed that 131 bands were amplified by 11 primers with an average of 11.9 bands per primer and 61 polymorphic bands were obtained with an average of 5.5 bands per primer, which revealed relatively high percentage of polymorphic bands (46.6%). The genetic similarity calculated from RAPD data varied from 0.668 to 0.994, and the 24 samples of Platycodon grandiflorum DC. cultivars were divided into 7 major groups on a criterion of 0.78 coefficient.

Key words: Platycodon grandiflorum DC., RAPD, genetic relationship
