【Abstract】 In order to revealthe subspeciesofrice cultivated during the Newlithic Age in Taihu Valley of Chi na,plantopals left in every soillayer were examined at Caoxie Hillvestige,and the subspeciesofancientrice culti vated there was determined during various culture periods.Meanwhile,DNA in carbonized paddy unearthed atthat site was successfully extracted,in which the cp DNA was furtheranalyzed.By testing and verifying each other with these two methods,the rice subspecies cultivated there during every ancienttime could be preliminarily identified. After amplification twice,electrophoretogram of DNA ofthecarbonized rice showed the same band as“Shenli”,the japonica control.At the same time,thediscriminantvalues ofplantopal sshapein every layerare largerthan0 5 . Itcan be concluded thatthe cultivated subspeciesisjaponica in every layeron this site.The results ofboth analyses show thatsubspecies ofricewhich havebeen cultivated in thatarea sincethe Newlithic Age areclassified asjaponi ca.更多还原
