Genetic diversity of 6 Angiopteris hokouensis populations collected from different habitats were analyzed by means of intersimple sequence repeat (ISSR) markers, and 8 proper primers with rich polymorphism and stable bands were selected from a total of 44 ISSR' s primers. The genome DNAs of the 6 populations were amplified to a total of 144 putative bands by the 8 primers, in which 96 were polymorphism bands. Polymorphism rate was 93.7%; Nei's gene di-versity index was 0.296, Shannon information index was 0.457, and Gst was 0.152 0. The genetic distance coefficient and the genetic similarity were 0.058 4-0.090 1 and 0.913 8-0.954 8. Cluster analysis by UPGMA indicated that the genetic distance between the populations related to spatial distance, as well as to habitats. The results showed that A. hokouensis populations had high levels of genetic diversity at disturbed habitats. Even there was no significant differentiation of ge-netic diversity among populations, the populations in moderate disturbed habitats had higher genetic diversity. The genetic diversity was not significantly related toaltitude, slope and aspect. [ABSTRACT FROM AUTHOR]
