Abstract: In the paper, DNA fingerprinting patterns of common vole (Microtus arvalis) were detected with HindIII, HinfI and microsatellite probe (GTG)₅. The results showed that legible DNA fingerprints were not produced with HindIII and probe (GTG)₅, however HinfI and probe (GTG)₅ produced abundantly informative DNA fingerprints. DNA fingerprints were individual-specific and represented higher polymorphism in number, intensity and distribution bands among individuals. The band-sharing rates (BSR) between individuals were determined by the DNA fingerprints. The average band numbersand average band-sharing rates in fragment length region (FLR) of >2.3 kb were 29.625±5.012 and 0.388±0.083 respectively. Correlative fingerprint-data with the population were calculated from average BSR. In this study,a technical basis is established for application of multilocus DNA fingerprinting in common vole.
