Although the current rice genome database potentially has great impact on agriculture, its effective application needs more genetic tools that facilitate to understand genetic control of traits of agronomic importance. This project was aimed to develop such tools (mapping populations for studying quantitative trait loci (QTL) for agronomic traits in rice). We developed for mapping populations, viz., Akihikari (lowland japonica) x IRAT 109 recombinant inbred lines, Nekken 2 (lowland japonica) x Gaya (lowland indica) recombinant inbred lines, Kamenoo (lowland japonica) x Dular (rainfed-lowland indica) recombinant inbred lines, and IR36 (lowland indica) x Genjah Wangkal (upland japonica) recombinant inbred lines. Many agronomic traits including germination ability have mapped using these population by researchers in Japan and China. These results were presented in the synpodium 'Why QTL information is needed in agronomy?' hold by us in the 2005 meeting of Japanese Crop Scicene Society. We also assessed the possibility to propagate and distribute these populations in cooperation with commercial company. We have successfully exchanged opinion and information with some leading companies in rice biotechnology.

尽管目前的水稻基因组数据库对农业有很大的潜在影响，但它的有效应用需要更多的基因工具来帮助理解农艺性状的遗传控制。本项目的目的是开发这样的工具(为研究水稻农艺性状的数量性状座位(QTL)绘制群体图)。我们开发了用于群体定位的Akihikari(低地粳稻)×IRAT 109重组自交系、Nekken 2(低地粳稻)x Gaya(低地稻)重组自交系、Kamenoo(低地粳稻)x Dular(雨地稻)重组自交系和IR36(低地稻)x Genjah Wangkal(旱地粳稻)重组自交系。日本研究人员和中国利用这些群体绘制了包括发芽力在内的许多农艺性状图谱。这些结果发表在《为什么农学中需要QTL信息？》由我们在2005年日本作物科学学会会议上举行。我们还评估了与商业公司合作传播和分发这些种群的可能性。我们已经成功地与一些领先的水稻生物技术公司交换了意见和信息。
