Method］ From 27 pairs of porcine microsatellite primers recommended by Food and Agriculture Organization of the United Nations and International Society for Animal Genetics, six pairs (S0155, SW240, IGF1, SW951, SW857, SW24) were selected for microsatellite DNA detection of three Guizhou local pig breeds including Nuogu Pig, Kele Pig and Guanling Pig. Subsequently, their genetic diversities were analyzed.

方法］ 根据联合国粮农组织和国际动物遗传学会联合推荐的27对猪微卫星引物，从中筛选出6对(S0155，SW240，IGF1，SW951，SW857，SW24)，用于对糯谷猪、柯乐猪、关岭猪3个贵州地方猪群体进行微卫星DNA检测，进而分析其遗传多样性。

Furthermore, it was found that some microsatellite loci of the three breeds deviated from Hardy-Weinberg equilibrium, where the majority of the variance in the Oncorhynchus mykiss was within populations (80.7%), and small proportion was among populations (19.3%).

在Hardy-Weinberg平衡条件下，进行了P检验，发现3个群体均有位点发生了显著偏离；对3个群体进行了Fst值计算，表明群体间存在着一定程度的遗传分化，但遗传变异绝大部分存在于品种内。
