摘要
对玉米、类玉米和薏苡染色体核型的比较结果显示，玉米属较不对称核型，类玉米和薏苡属较对称核型，因此玉米属于进化类型，类玉米和薏苡属于较原始类型．但是玉米与类玉米的相似点较多，它们的亲缘关系较近，它们与薏苡的差异较大，关系较远．三者的进化途径为：薏苡→类玉米→玉米．
The comparative studied results of chromosome karyotypes among Zea, Euchlaena and Coix show that Xea belongs to a more asymmetric karyotype, but Euchlaena and Coix to more symmetric karyotypes. So, Zea belongs to a evolutional type, but Euchlaena and Coix to more original ones. There are more similarities between in and Euchlaena than between them and Coix. From these results it can be concluded that Zea and Euchlaena have a nearer relation with each other and a more distant relation with Coix,their evolutionary way is:CoiX→Euchlaena→Euchlaena→Zea.
