In order to investigate important loci for rice domestication, QTL analysis of domestication-related traits was carried out with four backcross recombinant inbred populations derived from the reciprocal crosses between two rice cultivars (Japonica and Indica types) and an Asian wild rice accession. The results suggest that QTLs, commonly detected in the two populations having cultivated or wild genetic backgrounds, may have played important roles in the early phase of rice domestication.

为了研究水稻驯化的重要位点，利用4个由2个水稻品种（粳稻和籼稻）与1个亚洲野生稻品种正反交获得的回交重组自交群体，对水稻驯化相关性状进行了QTL分析。这些结果表明，在栽培和野生两个群体中普遍检测到的QTL可能在水稻驯化的早期发挥了重要作用。
