从供试材料中筛选到具有多态性的ISSR引物10条,利用这些引物对来自7个国家的48个亚麻品种的遗传多样性进行ISSR分析,共扩增到82条清晰的多态性条带,多态性比率为91.1%。用UPGMA法将48个亚麻品种聚为六大类,聚类结果表明地理位置相近的品种基本聚为一类,本研究结果可以指导亚麻育种亲本选配。 A total of 10 ISSR primers with polymorphism were screened from the tested materials. ISSR analysis of genetic diversity of 48 flax varieties from 7 countries was carried out using these primers, and 82 clear polymorphic bands were amplified With a polymorphism ratio of 91.1%. The UPGMA method was used to classify 48 flax varieties into six major categories. The clustering results showed that the varieties with similar geographic locations basically clustered into one category. The results of this study can guide the selection of flax breeding parents.
