Outline of Final Research Achievements

The purpose of this research is to develop new crops with high stress tolerances from wild legumes living in harsh environments. When doing this, it is possible to reduce the time and labor required if the domestication genes are already known. By treating a wild legume with mutagen, mutants with non-shattering pods or non-dormancy seeds were obtained. Genetic analysis showed that both mutations were dominated by a single locus. After detailed analysis, it was possible to narrow down the causative gene to several. This study found that domestication of wild legumes could be easily achieved. In future, by identifying causative genes we will be able to develop crops with various stress tolerances from wild plants.
