Abstract: One hundred and seven samples of two subspecies of striped field mice, Apodemus agrarius pallidior from Northern China and A . agrarius coreae from Korea, were used for the analysis of mitochondrialDNA (mtDNA ) fragment patterns resulted from the digestion with eight restriction enzymes by blot hybridization technique. 　　All 35 fragments and 12 mtDNA haplotypes were recognized. The 12 hap lotypes were grouped into two major subgroups with the mean divergence of 1.01%. One subgroup with four haplotypes consisted of 51 samples from four localities in Northern China, which is A . agrarius pallidior, and the other subgroup with eight haplotypes is composed of 56 samples from four localities in Korea, A . agrarius coreae.　　Subspecies coreae appeared to be some what diverged in their mtDNA geno types from subspecies pallidior, and taxonomic status of these two subspecies is confirmed in this molecular study. It becomes necessary to carry out further researches with samples of striped field mice from other localities to clarify subspecies classification of A . agrarius.
