In the study, 6 pairs microsatellite primers(S0155, SW240, IGF1, SW951, SW857, SW24) were selected in accordance to recommendation of Food and Agriculture Organization of the United Nations (FAO) and 27 pairs microsatellite primers of swine from literature. Microsatellite DNA detection was applied to 3 populations(90 samples) Guizhou local swine expecily Nuogu Pig with the filtered primers to research genetic structure and genetic relationship of Guizhou local swine in molecular level. The results sh...
