Ion beams have been utilized for the Sub-Project on Composition or Quality in Rice (FY 2007 - 2012) under the Mutation Breeding Project of the Forum for Nuclear Cooperation in Asia (FNCA). The aims of this project are to increase food production and to improve food quality in Asia by developing new rice mutant varieties. Seven participating countries, i.e., Bangladesh, China, Indonesia, Korea, Malaysia, The Philippines, and Vietnam joined this project and irradiated seeds of their own rice varieties with ion beams. So far, most of the participating countries completed to decide the optimal dose for mutation induction for each rice variety and harvested offspring. In several countries, useful mutant candidates such as high yield, early maturation, disease or salt tolerant and semi-dwarf have been obtained. These results indicated that ion beams showed great performance in improving the agronomic traits.
