Genetic diversity of 22 rabbit breeds were investigated using 10 microsatellite DNA markers. The results showed that the average number of effective alleles ranged from 3.0 to 4.6, and the polymorphism in-formation content (PIC) ranged from 0.4997 to 0.7009, showing highly polymorphic. The lowest genetic distance (0.0087) was observed between American rex rabbit and Germany rex rabbit, while the highest ge-netic distance (1.2712) was observed between Germany white rabbit and Changm. UPGMA cluster analysis based on genetic distance showed that the 22 breeds could be divided into three groups. The first group con-tained Jirong-Ⅰand Jirong-Ⅱ rabbit, Saibei rabbit and Habai rabbit comprised a second group, and the other populations in the third group. The results may provide theoretical basis for conservation and exploitation of rabbit breeds in China.
