| Outline of Final Research Achievements |
Iron (Fe) deficiency anemia is a very serious micronutrient problem in the world, especially in Asian countries where rice is a main staple food, including Japan. In this research, we applied ion-beam mutation and screening method to obtain high Fe and Zn rice. Heavy ion-beam (carbon ion 12C6+) was irradiated to the most popular rice variety in Japan, Koshihikari, at Japan Atomic Energy Agency (Takasaki, Gunma, Japan). Koshihikari mutant rice cultivated in the field on 2015 and 2016 were analyzed for metal concentration in the grains, and high Fe and Zn lines were selected in each generation. Fe or Zn concentration in polished seeds were increased up to 2 or 1.5 times, respectively, in selected mutant lines compared to wild type rice.
