| Abstract: |
| 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. |
