It is also a model experimental system because of its short life cycle and morphological, physiological, and genetic characteristics. Barley is used for, in order of importance, animal feed, brewing malts and human food. Barley is found in widely varying environments globally. It has wide adaptation ability to different climatic conditions and various environments comprising drought and irrigated environments (Nevo, 1992; Gomez-Macpherson, 2001).
