Abstract:

Rice (Oryza sativa) is one of the most important crops in the world and serves as a staple food source for more than half of the world’s population. Research into when, where, and how rice was initially cultivated and eventually domesticated is essential. Research on these questions has been greatly advanced recently, along with nearly continuous research in both genetics and archaeology using newly developed analytical techniques. Here, we review the scientific understanding of rice domestication in the Yangtze River valley from both an archaeological and genetic perspective, and discuss the relationship between rice domestication and the Yangtze River civilization. Recent genetic research suggests that domesticated rice (O. sativa ssp. japonica) first occurred in southern China, including the Yangtze River valley and the Pearl River Basin. Current findings from archaeology support the view that O. sativa ssp. japonica was firstly domesticated in the Yangtze River valley ca.10,000-8,000 BP, and rice cultivation and agricultural development triggered the Yangtze River civilization. These findings enhance our understanding of rice domestication and related cultivation culture and also have implications for conservation of plant resources in the Yangtze River valley.
