Genetic diversity analysis of four Zhejiang coastal Porphyra haitanensis strains with ISSR marker
利用ISSR分子标记技术分析浙江沿海4株坛紫菜的遗传多样性

The genetic diversity of four morphologically different Porphyra haitanensis strains collected from Nanji Island and Yushan Island of Zhejiang Province was analyzed with ISSR markers. In total, 11 primers were selected out from 33 primers for diversity analysis. These primers amplified 62 bands, and 88.71% of the bands were polymorphic. The genetic distance of the four strains of P. haitanensis ranged from 0.3226 to 0.6129. Two strains from Nanji Island were clustered together first, with other two strains Yushan Island joined then, indicating that the wild P. haitanensis along Zhejiang Provincial coast is rich in diversity.
