摘    要: 本文报道了中国编入目录的5225个栽培大麦品种的变种类型及其分布,共属233个变种,其中52个是国内外尚未报道的新变种。通过对五千余份材料的观察研究认为:我国栽培大麦具有窄护颖、齿芒、芒形多样性以及颖壳和粒色的深色型较多等特点;变种类型的分布与生态环境有密切关系。根据一个生态区内分布多个变种组成该区的变种群的原则,将我国栽培大麦划分为青藏高原裸大麦变种群、云贵高原短芒变种群、黄河流域密穗型变种群、长江中下游及华南变种群和北方春大麦区稀穗型变种群五个分布区。

关 键 词:变种  栽培大麦  分布

Abstract:This paper reports5 225forms in 233 varieties of cultivated barley in China. Among them 52 are first reported varieties. Observations and studies on samples of all these forms showed that the cultivated barley in China is characterized by narrow glume, denticulates and diverse awns, and dark-coloured ears and seeds in most varieties, These varieties with their distribution related closely to the ecological environment can be divided into 5 groups: naked barley in Qinghai-Tibet plateau, short awn barley in Yumman-Guizhou highland,compact ear barley in Yellow River Valley, variant group in the middle and lower reaches of Yangtze River and South China, and loose ear spring barley in the North China. Consequently, this provides further evidences to prove that the Qinghai-Tibet plateau is the P(?)imary center of origin of the Chinese cultivated barley, and Yunnan-Guizhou highland and Yellow River Valley are the secondary center of variation.
Keywords:Variety  cultivate barley  Distribution
