%X This paper deals with the comparicon of C-banding pattorns of all Rattas specics(8 speces) in China. And there are some differences among theis C-banded karyotypes . The cvolution of C-banding patterns of 8 spceics of rats has been studied, and the following tactors maybe facilitate karyotypic variability, loss of centromeric heterochromatin, interstitial heterochromatin, terminal hclcroch-romatin and hcterochromatic arms. Based on the different characteristics of C-banded karyotypes. R, yunn-anensis ,R. sikkimmensis and R. turkcstanicus may be classified into three independent species. Moreover, a cluster dendrogram has been presented in this paper by the fuzzy aggregation. It shows that these 8 species are able to diviele into two groups:R. rattus sladeni R. sikkimensis for the first group and R. fluvipectus, R. yunnancnsis. R. nitidus, R. losca, R. turkestanicus and R, norveyicns for the sccond.
