Abstract

For the spring ephemeral and myrmecochorous perennia, Corydalis filistipes Nakai (Fumaria-of the species were investigated with allozyme markers. Levels of genetic diversity (A=1.73, P95% = 61..2%, Ho= 0.201, He= 0.167) were relatively lower than those of other endemic species with widespread distribution range, but considerably higher than other endemic species with similar life history traits isolated in island. The moderate level of genetic diversity within subpopulations in C. filistipes is characteristic of the species with predominantly outcrossing, myrmecochorous seed dispersal by dual function of the elaisome and mode of sexual and asexual reproduction by the cleistogamy. The analysis of fixation indices showed an overall excess of heterozygotes (mean FIS=-0.1889, FIT=-variation was found among subpopulations (FST=0.0557). The strategies of reasonable conservation and management, and the maintenance mechanism of genetic diversity of Corydalis filistipes Nakai, endemic plant species in Korea were discussed.
