用多种方法对 1 997年湖南澧县八十遗址出土的 782粒 80 0 0年前的古栽培稻谷的粒形等性状分析研究 ,观察到该古栽培稻是一个具有广泛性状变异性的不同于现代籼、粳、普通野生稻的近野生稻偏籼型的独立复合群体 ,且在演化地位上具有原始性和过渡性的特征。

The characters of 782 grains of ancient cultivated rice at 8000 BP from Bashidang site in Lixian county were studied in various methods. The ancient cultivated rice was an independent and complicated colony with great variations which are more closed to indica and O.rufipogon; and an original and transitional state of it in the position of evolution were observed. It was deduced to be an original type of cultivated rice which had completely developed in nature without any artificial selection.
