鹅观草属系统演化研究进展

鹅观草属（Roegneria C.Koch）是小麦族类群中最大的属，拥有小麦（Triticum aestivum）等粮食作物所需的高产、抗病虫害、抗逆等优良基因。然而鹅观草属的分类系统、演化地位以及与其近缘属的演化关系等问题，迄今仍然处在争论之中。为了系统地认识和了解鹅观草属的系统发育概况，本研究结合国内外研究资料，对鹅观草属的确立、分类系统、系统演化、染色体组组成与分化的研究现状进行了综述。随着分子标记技术的日渐成熟，结合分子系统学、细胞学及传统形态学方法进行系统发育的研究，将成为有效的途径。

Advances in phylogeny and evolution studies of Roegneria

Roegneria Koch is the largest genus in the Triticeae Species groups. Within this genus there are many good resources, for example, the genes related to high yield, pest resistant and stress tolerance, and they are necessary for wheat and other grain crops. However, many issues are still in debate in Roegneria, such as the classification system, evolution status and evolutionary relationship with other related genera. This essay aimed to give better understanding of the phylogenetic profiles in Roegneria systematically. According to research data on the establishment of Roegneria, evolution status, genome composition and differentiation, an overview was given. With the development of the molecular marker techniques, the method for phylogenetic studies on Roegneria would become more effective, which combined with molecular systematics, cytology and traditional morphological techniques.
