The earliest direct dates of wheat in East Asia come from Donghuishan in Gansu Province, China. Few other dates of wheat in East Asia are direct dates. The previous direct dates at Donghuishan were obtained from wheat without secure context. New samples were taken from a stratigraphic profile at Donghuishan and directly dated. The wheat remains are earlier than any other directly dated wheat east of the Xinjiang Autonomous Region, but considerably later than the previously dated specimen from the same site. These new dates, from the early second millennium BC, are the earliest evidence of significant wheat and barley production and show that the Hexi Corridor played a critical role in the introduction of wheat to China.
