| 摘 要： | 应用SRAP (Sequence-Related Amplified Polymorphism) 分子标记对当前市场上推广的48个万寿菊杂交一代品种进行遗传多态性研究，用60个引物组合进行扩增，从中筛选到20个多态性引物组合，共产生289个多态性条带，平均每个引物组合产生14.45个多态性条带，显示了较高的多态性比率。聚类分析20个引物组合的扩增结果，48份材料分为两大类，Jaccard's相似系数在0.25～0.91之间。

| Abstract: | Study on genetic diversity of Marigold could benefit the research of cultivar property right protecting，seanged purity testing，and genetic breeding. A new molecular marker system-SRAP (Sequence-Related Amplified Polymorphism) was firstly applied on 48 marigold hybrids genetic diversity research. 20 primer pairs selected from 60 amplified 289 polymorphic bands with an average of 14.45 polymorphic bands perprimer pair. Cluster analysis using UPGMA method based on the data of SRAP amplified bands by 20 primer pairs showed 48 hybrids could be distinguished into two main groups. Jaccard s similarity coefficient ranged from 0.25-0.91. |
