Barley, as well as hexaploid wheat, can adapt broadly and ecologically, which differentiates it from other cereals. It is widely known that the domesticated barley landraces were genetically divided into the Western group, including the Near East ; Turkey ; the Mediterranean and Transcaucasus ; westward to Ethiopia and Europe; and the Eastern group, including Southwest Asia and eastward to the Himalayas, China, Korea, and Japan. Objective in this study is discovering the traits which would make it possible to expand the cultivation area into Asian region. We focused on pre-germination flooding tolerance, and relationship between the geographic distribution of extent of the sensitivity and population structure uncovering by molecular phylogenic analysis were comprehensively investigated. As the consequence, Far Eastern accessions would specifically acquired tolerance to the pre-germination flooding and might be adaptively evolved in order to expand the cultivation are in this regions.

大麦和六倍体小麦一样，可以广泛地适应生态环境，这是它不同于其他谷物的地方。众所周知，驯化的大麦地方品种在遗传上分为西部组，包括近东;土耳其;地中海和外高加索;向西到埃塞俄比亚和欧洲;和东部组，包括西南亚和向东到喜马拉雅山，中国，韩国和日本。本研究的目的是发现这些性状，以便有可能将栽培区域扩大到亚洲地区。本研究以种子萌发前的耐淹性为研究对象，通过分子遗传学分析，对种子萌发前耐淹性的地理分布与群体结构揭示的关系进行了综合研究。因此，远东加入将专门获得耐受发芽前水浸，并可能适应性进化，以扩大在该地区的栽培。
