摘　　要：染色体核型分析表明,膜荚黄芪[Astragalus membranaceus(Fisch.)Bge.]和蒙古黄芪[Astragalus mem-branaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao]均为二倍体,2n=2x=16,第8号染色体上均有随体;膜荚黄芪核型为2n=2x=8m(1SAT)+8sm,蒙古黄芪染色体核型为2n=2x=6m+10sm(1SAT);核型对称性分别为2A和2B型。该结果支持《中国植物志》关于蒙古黄芪为膜荚黄芪变种的观点。Karyotype of Astragalus membranaceus was carried out in this paper. The results showed that A. membranaceus Bge. and A. membranaceus.var.mongholicus （Bge.）Hsiao both were diploid, 2n=2x=16, and there was satellite in the 8th chromosome of two Astragalus;karyotype of A. membranaceus Bge.was：2n=2x =8m （1SAT）＋6sm ＋2st,karyotype of A. membranaceus.var.mongholicus （Bge.）Hsiao was： 2n=2x=6m＋10sm （1SAT）; the karyotype of two Astragalus was belonged to Stebbins＂ 2A and 2B type respectively, and the opinion of Chinese Flora that A. membranaceus.var.mongholicus（Bge.）Hsiao was the variation of A. membranaceus Bge. was supported.
