To man Triticeae is one of the most important tribes in the plant kingdom, comprising the temperate cereals wheat, barley, rye, triticale and several important forages. All ca. 350 wild taxa of the tribe thus constitute a gigantic gene pool to the crops. By necessity the primary gene pools have received the highest priority in collecting, evaluation and utilization. However, the wild and weedy taxa have in recent years received an increased attention, but the basic botanical and genetical knowledge is in many groups fragmentary. Even though collecting has been accomplished in many areas, there are still areas which have not been visited. Very limited knowledge is present on seed physiology, seed handling techniques, sampling strategies, and genetic diversity concerning wild species. Most Triticeae species are common over vast areas, but quite a few need special attention, being rare, or threatened by extinction.
