Present work was attempted to investigate the karyotype, the reciprocal translocation of chromosomes and the geographical distribution of three Paeonia species grown wild in Korea with the aim of elucidating the taxonomical affinities of the species. Prior to conducting these works, it was required to clarify the karyotypes of the cultivated varieties of P. albiflora which has been grown since long time ago in this coundtry for medicinal value. Present report is part of the series of karyotype studies now being extensively conducted using varieties (or lines) of P. albiflora collected across the country. Arm ratio, number of trabant, kind of trabant chromosomes and karyotype formula are different among the six cultivated varieties. Excepting one, five varieties used had invariably trabants on D and E chromosomes while no trabant was found in C chromosome.
