Abstract:  Genetic diversities of Wanzai black rabbit， Wanxi Angora rabbit and Belgian rabbit were studied using 13 microsatellite markers. The genetic diversity was disclosed by calculating the allele frequency， heterozygosity （Ho）， expected heterozygosity （He）， F value and genetic distance. It was shown that there were 3 imbalance locus in each of the above mentioned rabbit populations， indicating a rich genetic diversity. The average polymorphism information contents （PIC） of Wanzai black rabbit， Wanxi Angora rabbit and Belgian rabbit were 0.35， 0.48， 0.31， respectively. The average He were 0.40， 0.54， 0.37， respectively， and the average Ho were 0.39， 0.51， 0.35， respectively. The average genetic differentiation coefficient （Fst） value among populations was 0.120 1. The observed closest genetic distance was 0.145 2 between Wanzai black rabbit and Belgian rabbit， and the observed farthest genetic distance was 0.200 0 between Wanzai black rabbit and Wanxi Angora rabbit.

Key words: Wanzai black rabbit, Wanxi Angora rabbit, Belgian rabbit, microsatellite markers, genetic diversity
