摘　　要：鸭茅(Dactylis glomerata)是世界著名的优良冷季型禾本科牧草。和其他农作物相比,鸭茅分子遗传育种起步较晚,但近年来,随着分子生物学的发展和新技术的应用,鸭茅分子遗传育种发展迅速,目前已取得了一些初步成就。本文回顾了近年来国内外鸭茅在分子标记开发、种质资源的评价、遗传多样性分析、指纹图谱构建、遗传图谱构建、重要性状的基因定位、基因的遗传转化等方面的主要研究,并对当前存在问题进行分析及未来发展方向进行展望。Dactylis glomerata is a world famous cold-season grasses.As compared with the other major crops,the molecular breeding of orchardgrass began recently,and it has resulted in some preliminary achievements.This paper reviews the main research on molecular maker development,germplasm resources,genetic diversity analysis,fingerprinting,genetic map construction,gene mapping,and genetic transformation.Moreover,the existing problems in the practice were analyzed.Based on the discussion and analysis,some countermeasures were proposed.
