| 中文摘要: |
| 以福州市日溪乡自然居群的 38 份“生蕉样品为材料，采用 ISSR 分子标记并结合相关软件进行遗
传结构分析。 结果表明：筛选的 13 条引物共扩增得到 116 条 DNA 条带，其中多态性条带为 70 条、占 60.34%，
说明福州日溪“生蕉自然群体具有较高水平的遗传多样性； 通过 NTSYS 和 STRUCTURE 聚类分析将 38 份“
生蕉样品划分为 6 大类，结合 Q 值分析表明，福州日溪“生蕉群体内部存在着一定的遗传信息交流。 |

| Thirty-eight samples of wild banana leaves from Rixi town of Fuzhou were collected as materials, the
technical system of ISSR marker was used, and their genetic structures were analyzed by related software
STRUCTURE and NTSYS in the study. The results showed that based on 13 primers, 116 stable DNA fragments were
obtaimed, of which polymorphic band number was 70, accounting for 60.34%，which revealed a relative high level of
genetic diversity. The results of NTSYS and STRUCTURE analysis showed that 38 wild materials could be divided
into 6 groups. The Q-value analysis showed that there was a certain exchang of genetic information in the natural
populations of wild banana in Rixi town, Fuzhou city. |
