ISSR analysis on genetic structure of natural population in wild banana from Rixi town, Fuzhou city

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.
