Six field bean (GI-vcine soza S and Z ) plants were examined for their genetic polymorphisms and intraspecific variations using randomly amplified polymorphic DNA(RAPD) markers. In RAPD analysis of 5 random primers (Rp-1, Rp2, Rp-3, Rp-4, Rp-5), 30 of total 155 bands obtained kom 5 primers were polymorphic and sizes of polymirphic band ranged between 0.5 and 3.0 kb. Number of bands amplyfied per primer was varied from 2 to 11 and average number was 6.0. Genetic variation of intraspecies in the samples of six region was ranged behveen 11 to 25 percent, and genetic similarity among intraspecies was ranged from 0.69 to 0.78. In pairwise genetic similarity test of six field bean plants, Mun and Hoj showed highest coefficient of genetic similarity as 0.67, whereas Sin and Hoj was lowest as 0.45. According to the genetic similarity, the level of intraspecific variation is higher than that of regional distance in GI-vcine soza.
