| We determined the genetic diversity and population structures of Carex breviculmis (Cyperaceae) populations in Korea, using genetic variations at 23 allozyme loci. C. brevicuimis is a long-lived herbareous species that is widely distributed in eastern Asia. A high level of genetic variation was found in 15 populations. Twelve enzymes revealed 23 loci, of which 11 were polymorphic (47.8%). Genetic diversity at the speciesand population levels were 0.174 and 0.146, respertiveIy, Total genetic diversity ( $H_{r}$ = 0.363) and within-population genetic diversity ( $H_{s}$ = 0.346) were high, whereas the extent of the population divergence was relatively low ( $G_{ST}$ = 0.063). Deviation from random mating (F/suib IS/) within the 15 populations was 0.206. An indirect estimate of the number of migrants per generation (Nm =3.69) indicated that none flow was extensive among Korean populations of this species. Analysis of fixation indices revealed a substantial heterozygote deficiency in some populations and at some loci. Genetic identity between populations was high, exceeding 0.956.956. |
