Genetic diversity was compared and analyzed between Laminaria japonica gametophytes from
Qingdao of China and those from Hokkaido of Japan. Six enzyme systems ( Adh , Gdh , Idh , Lh , Sdh , and
Sod) were examined by PAGE , and twenty two gene loci were found. The results showed that the genetic diversity in the gametophytes of Hokkaido was higher than that of Qingdao. There was genetic differentiation in
gametophytes between Hokkaido and Qingdao. Double banding patterns of allozymes with different mobility
were found for Qingdao gametophytes in Idh , Ldh , and Sdh enzymes as well as for Hokkaido gametophytes
in all six enzymes. The bands may be controlled by special genes which mainly exist in the third gene loci.
