摘要
鸭茅是世界范围内广泛栽培的一种重要禾本科牧草 ,具有高产、优质、耐荫性强等特性。我国的野生鸭茅资源十分丰富 ,分布广泛 ,基因资源优良 ,但有关鸭茅的研究报导相对较少。为了更好地开发利用这一优良的牧草资源 ,本文从形态学、细胞学和分子水平对国内外鸭茅种质资源多样性的研究进行了综述 ,并对今后我国的鸭茅研究工作提出了建议。
Dactylis glomerata L. is a worldwide-cultivated species for its high yield, good quality and shade resistance. China also holds an extensive distribution of wild Dactylis. However, reports on researches on Dactylis glomerata are still rare. This review summarized the morphological, cytological and molecular diversities of Dactylis glomerata. Genetic polymorphism of Dactylis glomerata exits at all levels. It can be predicted that Systematical studies on genetic diversity of wild orchard grass rich in China should be very important to reasonable conservation, utilization and breeding of new varieties of Dactylis glomerata.
