| ABSTRACT |
|
The study of genetic diversity was carried out in the cultivated brown algae, Undaria pinnatifida (Harvey) Suringar. Although this species has been regarded as ecologically and economically important one, there is no report on population structure in Korea. Starch gel electrophoresis was used to investigate the allozyme variation and genetic structure of ten Korean populations of this species. Of the 18 genetic loci surveyed, six (33.3%) was polymorphic in at least one population. Genetic diversity was high at the species level (Hes = 0.146), whereas, that of the population level was relatively low (Hep = 0.068). Nearly 86% of the total genetic diversity in U. pinnatifida was apportioned within populations. The sexual reproduction, high fecundity, and colonization process are proposed as possible factors contributing to high genetic diversity. The indirect estimated of gene flow based on Gst was 1.54.
