The aim of this study was to investigate the genetic diversity of black goats using microsatellite genotyping. A total of nine microsatellite markers were used to genotype 60 black goats of Hualien propagation station, Livestock Research Institute. The allele number for all loci ranged between 2 to 9, and the mean allele number was 6.22±2.11. The mean values for observed heterozygosityg (Ho), expected heterozygosity (He), and polymorphism information content (PIC) were 0.53±0.02, 0.59±0.06 and 0.55±0.18, respectively. From the analysis of ETH10 marker, there were only two genotypes with 198/198（10%）and 208/208（90%）in the goat population. Therefore, Ho of this goat population was zero. The values of Ho and He deduced from other loci were almost no less than 0.5. PIC values obtained from the analyses of microsatellite markers except for ETH10 and ILSTS005 were larger than 0.5, and the mean values of all markers were also larger than 0.5, indicating that the genetic diversity of this goat population was high.
