本文报道了中国编入目录的5 225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读区的变种群的原则,将我国栽培大麦划分为青藏高原祼大麦变种群、云贵高原短芒变种群、黄河流域密惠型变种群、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。
This paper reports the varieties and distributions of 5 225 cultivated barley cultivars in China, totally 233 varieties, of which 52 are new varieties that have not been reported at home and abroad. According to the observation of more than 5000 materials, the cultivated barley in our country has the characteristics of narrow-retaining, deciduous and mantle-shaped diversity and more dark-colored types of chaff and grain color. The distribution of varietal types and ecological environment are close relationship. According to the principle of variable population of multiple read zones in an ecoregion, the cultivated barley in our country is divided into four groups: the barley barley population in the Qinghai-Tibet Plateau, the Amaranthus variabilis population in the Yunnan-Guizhou Plateau, the Miehui-type population in the Yellow River Basin, the middle and lower reaches of the Yangtze River, South China varietal populations and northern spring barley spike-type population five distribution.
