摘　　要：对湖南澧县大坪双堰东周遗址水井出土的3粒炭化稻谷和7粒炭化稻米进行形态分析,结果显示双堰古稻具有大粒性和许多类似于粳型的形质特征(包括双峰乳突等),表明它属于籼、粳之间的偏粳类型。与新石器时代遗址出土的古稻谷相比,双堰古稻的谷粒更宽、更厚和更重,表明其谷粒有向短而圆的粳型变化的趋势。Three ancient carbonized unhusked rice and seven carbonized rice grains from wells of the Eastern Zhou Dynasty ruins at Daping Shuangyan in Hunan were morphologically analyzed. The results showed that Shuangyan ancient rice has the features of big grain and many similar morphological characteristics （including bi-peaked tubercles） to japonica rice, indicating that it belongs to the intermediate form between indica and japonica subspecies that is in the amesiality of japonica. Compared with the ancient unhusked rice unearthed from the Neolithic ruins, Shuangyan ancient rice has wider, thicker and heavier grains, tending to japonica characteristics of short and round grain.
