Outline of Final Research Achievements

To establish molecular basis of important traits for the production of hybrid rice, we employed 69 accessions of the world rice core collection provided by the National Institute of Agrobiological Sciences Genebank. After successive backcross of a cutivar Taichung 65, we found accessions inducing cytoplasmic male sterility (CMS) and CMS-associated genes. We also investigated stigma exsertion rate, and found accessions showing high stigma exsertion rate and QTLs responsible for this trait. These information will be useful for the production of hybrid rice.
