Abstract: Nine Chinese indigenous goat breeds and Boer were genotyped using 16 microsatellite markers recommended by the FAO and ISAG. 15 of the 16 microsatellite markers which had more than four alleles were used to analyze the genetic variation within the population and the genetic relationship and structure among the populations. A total of 159 microsatellite alleles were detected. Mean F-statistic (0.105) for nine indigenous breeds indicated that 89.5% of the variation was detected within the breeds and 10.5% of the genetic variation existed among the indigenous breeds. The UPGMA phylogenetic tree was constructed based on Da genetic distance and three clusters was obtained. The Boer separated from the indigenous breeds and formed one cluster. The indigenous goat breeds were divided into two clusters. The analysis of the population for the ten breeds showed they were separated into four clusters. The results showed that the population relationship is nearly the same to the UPGMA phylogenetic tree. 
