Abstract:

The genetic diversity and genetic structure of 15 natural populations of Castanopsis hystrix in China were analyzed using ISSR markers. Results showed that the genetic diversity of C. hystrix was abundant, with percentage of polymorphic bands(PPB) and Shannon's phenotypic diversity index(H0) being 94.89% and 0.387 3 at the species level, 76.93% and 0.305 0 at the populations level, respectively. There were significant genetic differentiation among and within populations, and 11.25% of genetic variation existed among populations. The Mantel test showed that the geographic and genetic distances were not significantly correlated to each other. The present study provided a scientific basis for the conservation and utilization of genetic resources of C. hystrix.

Key words: Castanopsis hystrix, ISSR, genetic diversity, genetic structure
