摘 要：
根据全国314个主要栽培大麦品种的书面材料和标本,鉴定出它们属于普通大麦种、二棱大麦和多棱大麦两个亚种,共82个变种,其中新变种28个。多棱大麦变种占83％,稞大麦多于皮大麦。变种中以稀穗、长芒、齿芒,穗和籽粒深色(黑、褐、紫、兰绿)、长毛小穗轴等类型占多数。二棱大麦以nutans和erectum,多棱大麦以pallidum,parallelum,pyramidatum,coelcste,revelatum和nudipyramidarum等变种分布较广。变种数、深色型变种和多棱大麦变种的分布频率都以青藏高原为最高。因此认为,多棱大麦是我国主要栽培类型,青藏高原可能是我国栽培大麦的起源中心。

摘 要：
314 main cultivars of barley in china have been identified, according to their local notes and accessions. The results show that they belong to the species Hordeum vulgare(L.) Hsü With two subspecies: ssp. H. distichon(L.) Hsü and ssp. H. vulgare(L.) Hsü, and are classified into 82 botanical varieties, among which 28 are new varieties. varieties of six-rowedbarley account for 83%, of total, of which the naked barley forms the greater part than the hulled. The majority of varieties are those withlax spike, narrow glume, long awn, rough awn, dark-coloured(black, brown, purple, dark-green) ear and seed, long-haired rachila. The more wide distributed varieties of two-rowed barley are nutans and erectum, and those of six-rowed barley are pallidum, parallelum, pyramidatum, coeleste, revelatum and nudipyramidatum. The number of varieties, and the frequency of distribution of dark-coloured varieties and of six-rowed ones are the highest across the Qinghai-Xizang Plateau. Consequently, it may be concluded that six-rowed barley is the principal cultivat d form in China, and the Qinghai-Xizang Plateau might be the center of origination of the Chinese cultivated barley.
