云南保山昌宁达丙营盘山新石器遗址出土古稻研究

Study of the Rice Remains from the Neolithic Yingpanshan Site at Dabing of Changaing in Baoshan,Yunnan

用性状差异显著性测定、欧氏距离比较、粒型判别函数等方法,对云南保山昌宁达丙营盘山新石器遗址出土的145粒完整炭化稻米,经过复原为新鲜稻谷后,通过综合分析认为:保山昌宁营盘山古稻属于倾粳稻类型的栽培古稻群。在判别函数和距离测定数据指标上都属于粳稻类型。与参照系的各个性状差异极显著,包括与粳稻亦然;表明粒型与现代粳稻亦有不相同之特点。其粒型短而厚重的演化特点,表现为近圆形的重粒类型。

One hundred and forty-five complete carhonized rice grains from Baoshan Changning Dabingying Panshan Neolithic ruins of Yunnan were restored by calculation and compared with O. mfipogon, other ancient rice, indica and japonica in grain shape, charaeter difference and Euclidean distance coefficient. The result indicates that the Baoshan Changning Yingpanshan ancient rice has tendency to trend-japonica type ancient cultivated rice. In the aspect of discriminant function and measurement data from the target, the rice belong to japonica type. Comparing to the frame of reference, each character difference is apparent, including japonica; this shows that these grain shape are different from traits of modem japonica. The grain shape of evolution is short, thick and heavy, which shows heavy grain type of near roundness.
