| Outline of Final Research Achievements |
Minerals and amino acids in grains are important as nutrition. Increasing a concentration of minerals and amino acid in grains are expected to improve nutritional conditions not only for plant themselves but human living who eating crops. In this study, I focused on genetic factors in wild rice that can improve mineral concentrations or amino acid concentrations in rice grains.
In order to identify genetic factors from wild rice, I used 6 wild rice introguression lines as a source of wild rice germplasm and performed large scale screening of their grain traits. I could find wild rice introguression lines that had high iron or zinc concentration and high lysine or isoleucine concentration in grains. Furthermore, I could develop molecular markers that link high iron concentration in rice grain.
Germplasm and molecular markers identified and developed in this study would be a important tools for breeding of rice grain nutrition in the future.
