花生的分类及种质资源

花生属（Arachis L.）有80多个种，原产地均在南美洲，大部分种质具有抗性强、耐践踏、耐牧、持久性强等一种或几种特性且能生产数量可观的绿色饲料。通过介绍国外对花生的分类和花生种质资源的研究以及国内少量的引种表现认为，花生属的种质资源较为丰富，且其中优良者居多，因此，开展广泛的引种研究工作，解决热带亚热带豆科牧草（尤其是混播草地）的持久性问题，在生产上具有重要的意义。

Taxonomy and germplasm of Arachis

There are over 80 species in the Arachis L. Most of them are good forage plant and has one or more characters of pest, disease tolerance, high yield and persistent in the tropic and subtropic area. Based on the performance of some introduced species, we think it is important that Arachis species should be introduced to solve the persistent of legume in tropic and sub tropic area
