大麦属的分类,过去基本上是按形态学来划分的,其中栽培大麦的分类比较混乱。近年来由于细胞遗传学的发展,中外学者们对大麦的分类提出了一些合理意见,即根据细胞遗传学上的差别和生殖隔离机制来划分种一级,结合形态学、生态学来划分亚种和变种。我国过去对栽培大麦的分类和变种名称的订定没有一个成套的规范,国外有关栽培大麦的分类和变种检索资料,各有见解,很不统一,而且有一些分类体系很不符合我国实际情况。
Classification of barley, the past is basically divided by morphology, of which the classification of cultivated barley more confusion. In recent years, due to the development of cytogenetics, Chinese and foreign scholars have put forward some reasonable opinions on the classification of barley, that is, according to the differences in cytogenetics and reproductive isolation mechanism to classify a species, with morphological, ecological division of subspecies And variants. In the past, China did not have a complete set of norms for the classification and classification of cultivated barley. The information on the classification and variety search of cultivated barley in foreign countries is very different from each other, and some classification systems are not in line with China’s actual conditions.
