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。
Based on the written materials and specimens of 314 major cultivated barley varieties in the country, they were identified as 82 subspecies of common barley, 2-row barley and polygamous barley, with 28 new varieties. Polygonal barley varieties accounted for 83%, barley more than barley. Variants in the spike, long-mans, teeth, ear and grain dark color (black, brown, purple, blue-green), long hair spike axis and other types accounted for the majority. Two-rowed barley with nutans and erectum, polygamous barley pallidum, parallelum, pyramidatum, coelcste, revelatum and nudipyramidarum other varieties are widely distributed. Varieties, dark-colored varieties and polygamous barley varieties are distributed in the highest frequency of the Tibetan Plateau. Therefore, Polygonum barley is the main type of cultivation in our country. The Tibetan Plateau may be the origin of cultivated barley in China.
