Through the analysis of macro-and micro-plant remains,food residues and the rice-field like features from the mid-Neolithic site of Hanjing in the Huai River region,we propose an early beginning of rice cultivation at *** presence of non-shattering rice spikelet bases and the increasing percentages of rice phytoliths confirm the appearance of domesticated rice in the Hanjing archaeobotanical ***,as indicated by the different prediction rates of rice domestication shown by morphometric of the double-peaked Oryza-type glum cells and fish-scale decorations on the Oryza-type bulliform cells from different cultural phases before 7,000 a BP,rice cultivation was at an early stage of *** findings provide new and significant evidence towards the establishment of the Huai River as another important center for early rice cultivation and domestication in prehistoric China.

rice （Oryza sativa） was first domesticated in the lower and middle Yangtze regions of China, and rice remains have been found in many Chinese archaeological sites. Until now, only phenotypic archeobotanical evidence, such as the spikelet bases of ancient grains, has been used to speculate on the domestication process and domestication rate of rice. In this study, we sequenced 4 genomic segments from rice remains in Tianluoshan, a site of the local Hemudu Neolithic culture in the low Yangtze and two other archaeological sites （2400 and 1200 BC, respectively）. We compared our sequences with those of the current domesticated and wild rice （O. rufipogon） populations. At least two genotypes were found in the remains from each site, suggesting a heterozygotic state of the rice seeds. One ancient genotype was not found in the current domesticated population and might have been lost. The rice remains belonged to the japonica group, and most if not all were japonica-type, suggesting that the remains might be at an early stage of indica-japonica divergence or an indica-japonica mixture. We also identified sequences with significant similarity to those from species of Sapindales, Zygophyllales, and Brassicales, which is consistent with the identification of other plant remains in the Tianluoshan site and the common rice field weeds such as mustards in southern China.
