| Outline of Final Research Achievements |
If we can produce rice varieties with high iron and zinc nutritional values, we can contribute to solve the iron deficiency anemia and zinc deficiency problems for Japanese and world population. Six generations of Koshihikari mutant lines were grown in the field and selected for their high iron and zinc nutritional values. We also crossed the lines with rice varieties that can be grown in Akita Prefecture and have good eating quality, aiming to produce a new brand of rice for local peoples and farmers. The whole genome sequences of the backcrossed lines between the mutant and the wild type were analyzed by next-generation sequencing. It suggested that the causative gene was located in the area of chromosomal loss in the mutant strain.
