| Abstract: | The reproduction of population of Apodemus chevieri in Dafang county of Guizhou province was investigated during 1996～1998. A to ta1 of 520 specimens were collected and dissected,among which 264 were female a nd 256 male.In main propagating season,the mean pregnancy rate,litter size and reproductive index were 18.62%,6.03 and 0.6846，respectively.The fluctuations of the rate of testis in serotum were identical with the rate of female pregnan cy. |
