摘要：

采用普通压片法，以仙客来叶芽为试材对3个国内常见品种（系）的核型进行了研究，结果表明3种仙客来染色体均为二倍体，染色体数目为2n=84，核型可分为3种类型：2n=2x=84=84m、2n=2x=84=47m+30sm+7M和2n=2x=84=83m+1M；未观察到次缢痕或随体；3种仙客来染色体均属小染色体，法国彩云系列和浙江森禾国旗红系列为1B型，核型相似；比利时镭射系列为1A型。

Abstract:

The karyotype of three Cyclamen persicum Mills was studied by the method of squash with the young leaves. The results showed that all the chromosomes were diploid; The karyotypes were divided into three types, i. e. 2n=2x=84=84m type, 2n=2x=84=47m+30sm+7M type and 2n=2x=84=83m+1M type. There was no satellites found in the morphological observation of chromosomes; all the three types were small in size; The karyotype of France iridescent cloud series and Zhejiang sen-he series belonged to 1B type , There was great similarity of karyotype among the germplasms. The karyotype of Belgium laser multi series belonged to1A type.
