| 摘 要： | 以8个姜品种的芽为试验材料，利用ISSR分子标记技术对它们进行遗传多样性分析。结果表明：筛选出的24条ISSR引物，共扩增出166个条带，其中55条为多态性条带，多态性比率为35.67%；8个姜品种的遗传距离在0.212 8~0.842 1之间，在λ=0.44处，可将供试的8品种分为3大类。供试8个姜品种多态性不高，5个自育品种和其他3个供试品种在遗传距离、亲缘关系、聚类结果各不相同，可进一步进行研究。

| Abstract: | Taking 8 sprouts of ginger varieties as materials, this paper analyzed and evaluated of the genetic diversity of 8 varieties of Zingiber officinale Rosc. by ISSR. The results showed that 24 ISSR primers were selected, and 166 bands were amplified with them, among which 55 bands were polymorphic, and their polymorphism percentage was 35.67%. The genetic distance of 8 ginger varieties was between 0.212 8~0.842 1. At λ=0.44, the materials could be divided into 3 categories. The genetic diversity of 8 germplasm resources was lower, 5 self-varieties and 3 other varieties were different in genetic distance, genetic relationship, clustering, so they could be further studied. |
