| 摘 要： | 本文利用骨髓染色体制片法，对棕背Ｃｌｅｔｈｒｉｏｎｅｍｙｓｒｕｆｏｃａｎｕｓ的核型进行了研究。结果表明，其二倍体数目为５６，常染色体由２个中着丝粒染色体和５２个端着丝粒染色体组成，Ｘ染色体为端着丝粒染色体。核型公式为：２Ｍ＋５２Ａ＋ＸＸ（Ａ，Ａ）。结合前人的报道，属动物的核型在进化中显示出其保守性。

| Abstract: | The karyotype of red backed mouse, Clethrionomys rufocanus, has been analysed by using bone marrow cells.The karyotype consists of 2 small metacentric and 52 acrocentric autosomes,and X chromosome is acrocentric.It should be noted that a number of species of genus Clethrivnomys revealed karyotypes similar to C.rufocanus, although minor differences have been found. |
