【摘要】 中国栽培稻起源演化研究已有较大进展，“贾湖古稻”“彭头山古稻”的发现，证明我国栽培稻至少有8000多年的历史，普通栽培稻起源于中国已成共识。但野生稻如何演化为栽培稻的实验遗传学证明仍待研究。本文报道，中国普遍野生稻经60Co射线处理后M2代数量性状变异情况，分析野生稻主要数量性状的遗传调控，为普通栽培稻的起源演化提供实验遗传学依据。更多还原

【Abstract】 The study of the origin and evolution of the cultural rice of China has obtained a greateradvancement. The discovery of "Jiahu Old Rice"and "Peng Toushan Old Rice"proved that the history of the cultivation of rice in China has been 8000 yare at least. A common knowledge that the origin of the common cultivated rice was in China is accepted by everybody. However, the experimentalgenetic proof of how the cultivated rice evoluted from wild rice is still a problem for studying. Theauthor reported the algebraic quantity characteristic variation conditions of M2 after the treatment of 60Co radiation to the China common wild rice,analysed the genetic control of the main quantity characteristics of the wild rice and thus provided the experimental genetic basis for the origin and evolution of the corn cultivated rice.更多还原
