Abstract

The distribution of a saccharinan kelp that is similar to <i>Saccharina japonica</i> was confirmed in Hidaka region, Hokkaido. As a result of amplified fragment length polymorphism (AFLP) analysis for the study individuals from Utoma in Hidaka region and the four varieties of S. japonica, genetic similarity (S) shows significantly higher value and genetic differentiation coefficient (G_ST) shows lower value both between the study individuals and S. japonica var. japonica. The structure analysis based on the limited AFLP data about the study individuals and S. japonica var. japonica showed two clusters in all samples. The cluster dominant in the study individuals was the same as the one dominant in the individuals collected from the inner part of the Uchiura Bay. Accordingly, the study individuals should be treated as S. japonica var. japonica and it is inferred that the individuals were introduced from the vicinity of boundary of Iburi and Oshima regions to Hidaka region.
