Abstract
|
|
|
|
Trifolium pratense (red clover, Fabaceae) is a short-lived herbaceous species and the species is introduced from Europe or North America to Korea approximately 60 years ago. Allozyme variability was examined in populations representing this species. A high level of genetic variation was found in T. pratense populations. Ten of 19 loci (52.6%) showed detectable polymorphism. Genetic diversity was 0.220. The sexual reproduction, high fecundity, and colonization process are proposed as possible factors contributing to high genetic diversity. Genetic diversity (0.220) was lower than that (0.285) of North American red clover, T. pratense. Korean populations of red clover may be founded by a small sample of larger or moderate populations. An indirect estimate of the number of migrants per generation (Nm = 4.20) indicated that gene flow was extensive among Korean populations of this species.
