Abstract: Using partial sequences of mtDNA control region,we sought genetic diversity,population genetic structure and subspecies classification in 5 populations of Myodes rufocanus from Northeast China and Hokkaido,Japan. After sequencing a 616 bp segment of control region,we detected 45 haplotypes based on 57 variable sites among 55 individuals. Our results revealed that high-level haplotype diversity and slightly less nucleotide diversity occurred in these populations. AMOVA analysis showed that high-level genetic differentiation happened between populations due to 64.70% genetic diversity and Fst ranging from 0. 240 to 0. 814. In a phylogenetic analysis,the haplotypes from Northeast China split into two groups:Daxing’anling-Xiaoxing’anling-Wandashan and Hailin-Dahailin. This suggested that we can separate the populations from Northeast China into two subspecies,M . r. irkutensis and M. r. Changbaishanensis respectively corresponding with the former and latter areas.
