| Research Abstract |
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.
