%X The present paper reports the chromosome numbers and karyotypes of 9 populations of Allium przewalskianum(Liliaceae). The results are as follows: the populations distributed in lower altitudes such as Huangyuan,Xining and Gonghe are diploid,with karyotype formulas,2n=2x=16=14m+2st(2SAT) (Huangyuan population,Xining population) and 2n=2x=16=12sm+2st(2SAT) (Gonghe population);other population distributed in higher altitudes such as Maqin Yushu,and Nangqian are all tetraploid with 2n=4x=32=28m+4st(2SAT)(Yushu population 1,Nangqian population 1),2n=4x=32=24m+4sm+4st(Maqin population,Yushu population 3) and 2n=4x=32=26+2sm+4st(Yushu population 2).
