| Outline of Final Research Achievements |
In crop breeding, efficient transmission of agriculturally important genes from wild relatives is necessary for overcoming difficult missions. However, technical problems such as reproductive isolation between crops and their relatives make it difficult to use comprehensively the genetic resources in wild relative populations. Towards complete use of a wild wheat relative Aegilops tauschii for bread wheat breeding, the goal of this research is set as map-based cloning of Net2 and Hch1, which are the D-genome causal genes for hybrid incompatibilities shown in interspecific hybrids from crosses between tetraploid wheat and Aegilops tauschii. Through this project, fine maps for Net2 on chromosome 2DS and Hch1 on chromosome 7DS were successfully constructed, and some BAC clones around the Net2 and Hch1 regions were selected. These progresses are important for further map-based cloning of Net2 and Hch1.
