鸭茅物种起源与系统发育分析研究进展

鸭茅（Dactylis glomerata L.）分布广泛，在世界各地均有种植，其在畜牧业发展和改善生态环境等方面起着重要的作用。自然界中野生鸭茅种质资源丰富、基因优良，具有非常大的开发利用潜力，研究鸭茅的进化关系，对鸭茅育种和品种改良具有重要意义。对鸭茅物种起源与分化的研究，不同的方法得到的结果不同，但仍没有统一分类标准来准确将鸭茅进行分类。本文通过对鸭茅的起源、进化分类及系统发育分析的研究现状进行了综述，为进一步研究鸭茅的起源及分类提供理论基础，并对于指导野生鸭茅的种质资源收集、保护和利用及开展相关基础研究具有重要意义。

Research Progress of Dactylis Species Origin and Phylogeny Analysis

Dactylis glomerata L. was widely distributed and cultivated all over the world. It plays an important role in animal husbandry development and ecological environment improvement. There were abundant germplasm resources and excellent genes in the natural world,which have great potential for development and utilization. Different methods have obtained different results in the study of species origin and differentiation of Dactylis,but there was still no unified classification standard to accurately classify Dactylis. In this paper,the origin,evolutionary classification and phylogenetic analysis of Dactylis were reviewed,which provided theoretical basis for further research on the origin and classification of Dactylis,and was of great significance for guiding the collection,conservation and utilization of germplasm resources of Dactylis and carrying out related basic research.
