Notes on the recent discovery of ancient cultivated rice at Jiahu, Henan Province: a new theory concerning the origin of Oryza japonica in China

Abstract

China is one of the places for the origin of the Asian cultivated rice (Oka 1988), but there are different theories for precise locations where ancient cultivated rice first originated, including those proposing South China and Yunnan (Li 1989) or the middle and lower Yangtze River Valley (Yan 1989), or the middle Yangtze and the upper Huai River Valley (Wang 1996) as the site of the oldest rice cultivation in China. The discovery (Zhang et al. 1994) of ancient rice at Jiahu in Henan province not only pushed the history of rice agriculture in the Huai River region back to 9000 BP, but also indicated the existence of an agricultural tradition of rice cultivation in the region from the beginning of the Holocene Anathermal until the end of the Holocene megathermal.
