【摘要】 近三十年来,国内外共报道了中国栽培大麦分类含1个种3个亚种353个变种,其中我国特有变种248个,主要是通过考察和继续征集发现的,大部分新变种是80年代中后期报道的。继已报道的172个西藏栽培大麦新变种之后,本文再报道新变种105个,这说明西藏高原确实是我国栽培大麦(尤其是多棱裸大麦)遗传资源最丰富的地区。这对系统了解中国大麦的分类,认识、研究和进一步利用资源都有其深远意义,同时为研究大麦起源、演化提供佐证。更多还原

【Abstract】 1 species, 3 subspecies and 353 varietiesofcultivated barley have been found in China for the past 30 years according to domestic and external reports, of which 248 varietes are specific to China.And most of them have been reported since the mid and late period of 80’ s through continuous survey and collections.This article reports additional 105 newly found varieties cultivated in Tibet apart from 172 varieties reported previously in the same journal.This article indicates that Tibetan Plateau is the richest region of barley (especially poly-rowed naked kernel barley) genetic resources.It illustrates that it is very important to understand the classification, recognition, research and further utilization of barley in China systematically and provide evidece for further research, origin and evolution of barley.更多还原
