| Research Abstract |
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.
