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.

尽管当前的水稻基因组数据库可能对农业有很大的影响，但其有效的应用需要更多的遗传工具，以促进了解农艺重要性特征的遗传控制。该项目的目的是开发此类工具（用于研究大米中的农艺性状的定量性状基因座（QTL）的种群。 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（高地Japonica）重组近交系列。日本和中国的研究人员使用这些人群进行了许多农艺特征，包括发芽能力。这些结果是在“为什么需要在农艺学中需要QTL信息的？”中提出的？我们在2005年日本农作物学会会议上举行。我们还评估了与商业公司合作传播和分发这些人群的可能性。我们已经成功地与一些水稻生物技术领域的一些领先公司交换了意见和信息。
