High energy heavy ion beam （80 MeV/u） radiation, as a new mutation breeding technique, has been applied in wheat, sweet sorghum and other crops, but there is still a gap in the research and application of japonica rice breeding in north China. In 2013, the researchers of the Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences did a series of work about the northern japonica rice mutagenesis breeding under high-energy heavy ion beam（¹²C⁶⁺）radiation by the national large heavy ion accelerator. After ten years of research and development, we first established the “less but better” mutation breeding technology system of northern japonica rice under high-energy heavy ion beam radiation in China. In this paper, we summarized in detail of radiation parent selection, radiation parameters establishment, progeny materials planting and selection and new varieties breeding, as well as discussed and considered the problems of the sensitivity of radiation parents, natural hybridization of M₁ materials, “crazy separation” of high-generation materials and so on. It is expected to provide a reference for the future breeding of rice induced by high-energy heavy ion beam radiation.
