Currently mainstream EMS (chemical mutagens) has a mutation rate 15 to 300 times higher than gamma rays and heavy ion beams (radiation)!
The fast neutron beams used in neutron beam breeding are high LET (Linear Energy Transfer) radiation, which can cut the double strands of plant DNA at multiple locations with high energy. This allows for the easy acquisition of "large mutations" with "high efficiency" in a single irradiation. The mutation rate for rice (Nihonbare) and Arabidopsis thaliana is reported to be 3-26% based on second-generation results. This is 15 to 300 times higher than the mutation rates achieved with currently mainstream methods such as EMS (chemical mutagen), gamma rays, or heavy ion beams (radiation). Due to this high mutation rate, the period required to create new strains can be significantly shortened, making neutron beam breeding a promising alternative technology to gamma rays and heavy ion beams for future applications. *For more detailed information, please refer to the related links.

Company information
Starting as a private company initiated by local volunteers under the proposal of the Ibaraki University Graduate School of Science and Engineering, we aim to develop a new technological domain that is globally competitive through collaboration between radiation-related facilities concentrated in Ibaraki Prefecture and the vibrant agriculture in the region. Our goal is to commercialize the use of neutrons for crop improvement, which, while considered effective among experts, had not been socially implemented, thereby contributing to the realization of a sustainable society. We have conducted repeated demonstration experiments, enabling the generation of dynamic and large quantities of mutants that were previously unattainable. In 2020, we patented the technology for generating mutagens using neutrons, and we are currently providing solutions not only for crop improvement in agriculture but also as a useful technology for the development of industrial microorganisms, catering to companies and research institutions engaged in biological breeding and variety development.
