大麦属的分类,过去基本上是根据比较形态学来划分的,其中栽培大麦及其近缘野生大麦的分类比较混乱。种、亚种和变种的界限不明,层次重叠。近年来,由于细胞遗传学的发展,因内外学者们对栽培大麦及其近缘野生大麦的分类,提出了比较合理的意见,那就是根据细胞遗传学上的差别和生殖隔离机制来划分种一级,按形态学、生态学等特征来划分亚种和变种级。我国过去对大麦的分类和变种名称的订定,没有一个成套的规
Classification of the genus Barley, the past is basically divided according to comparative morphology, of which the classification of cultivated barley and its associated wild barley more confusing. Species, subspecies and variants of the unknown, overlapping levels. In recent years, due to the development of cytogenetics, due to the domestic and foreign scholars on the classification of cultivated barley and its neighboring wild barley, put forward a more reasonable opinion, that is, according to the cytogenetic differences and reproductive isolation mechanism to species Level, according to morphology, ecology and other characteristics to divide subspecies and variety level. In the past, the classification of barley in our country and the definition of variety names did not have a complete set of rules
