Abstract:

Brown-eared Pheasant (Crossoptilon mantchuricum) is a critically endangered endemic species, which is listed in the national first-class protected birds in China. In this study, ISSR markers were used to investigate the genetic diversity of two populations of Brown-eared Pheasant in the Pangquangou Nature Reserve and Taiyuan Zoo. Ten primers out of 20 ISSR primers were selected for amplifying 35 samples of the two populations, and 65 clear amplification sites (PPB=76.9%) were obtained.The percentage of polymorphic bands of the two populations was around 54.10%.Shannon's Information Index of the two populations was 0.302 5 and 0.205 6, respectively. The generic heterogeneity (Gst), genetic flow (Nm), genetic similarity index indicated that there was no significant genetic differentiation between the two populations. Statistical analysis and cluster tree diagram consistently illustrated that the genetic diversity between the two populations was at a low level. Individuals in each population had close genetic relationship. The result in this study were consistent to another study we did with the mitochondrial genome genetic diversity.
