摘　　要：小麦族(Triticeae)是禾本科、早熟禾亚科中一个有重要经济价值、以多年生植物占优势的族,族内绝大多数种类是重要的粮食作物和畜牧业上的优良牧草,饲用价值极高,有些种类具有耐寒、耐旱、耐碱等特性,是农牧业上良种繁育、牧草利用的重要基因资源。但该族同时又是分类学上的一个疑难族,各学者对族内系统分类意见不一、争议颇大,尤其在族的界限、族下类群划分以及类群演化关系上问题较多,至今尚未解决。查阅了国内外分类学文献,探讨其分类差异以及存在问题,为充分开发利用中国丰富的小麦族植物资源提供理论依据。Triticeae is a tribe with important economic value and perennial plants predominating in Pooideae （Poaceae）. A large num- ber of them are important food crops and good grazing grasses. Furthermore, some of them have perfect characteristics in enduring cold, draft and alkaline. Consequently they are always used as important germplasm resources for grass breeding and improved breeds of crops. Despite decades of intensive efforts, there are still many unsolved questions, such as the definition of Triticeae, taxonomical classification and evolutionary relationships of Triticeae species. The systematic difference and existing problems were discussed by re- ferring to taxonomic references of home and abroad in this article. This report provided the theoretic foundation for research and utiliza- tion of abundant plant resources of Triticeae in China.
