Abstract: Physical remains of ancient rice could provide direct evidence to explore the origin and domestication of rice, and also lay a foundation for analysis of grain shape of ancient rice. In this study, time and space distribution of archaeological sites with rice physical remains was described and the change rule of grain shape of ancient rice based on essential data from predecessor was analyzed to explore rice origin and the route of dissemination. The results showed that ancient human began to choose grain shape of ancient rice consciously about 7 000 years ago, and noticed the grain width earlier than length. The middle and lower reaches of the Yangtze River were the original center of rice. After the origin of rice in the mid and lower reaches of the Yangtze River, it began to spread to the north and south separately. Under the influence of climate difference between the north and south, the japonica and indica sub-species split apart from each other finally.
