Recently, three new rice varieties "Dongdao 211", "Dongdao 812" and "Dongdao 862" cultivated by the rice high-energy heavy ion beam radiation mutagenesis breeding team of the Northeast Geographical Institute passed the 2022 Jilin Province Crop Variety Approval
.
2022 is the year in which the breeding team passed the largest number of approved rice varieties after the cultivation and approval of the first new high-energy heavy ion beam radiation mutagenetic rice variety "Dongdao 122" in China in 2020

.
In the past 20 years, the scientific research and breeding of japonica rice in northern China has made great progress, but there are still problems such as
single breeding technology, new breeding technology innovation and insufficient application.
In order to meet the needs of the structural reform of the rice supply side, it is urgent to upgrade and innovate the breeding technology of northern japonica rice to facilitate the cultivation of breakthrough major varieties
.
Since 2012, the Northeast Institute of Geography and Agroecology of the Chinese Academy of Sciences and the Institute of Modern Physics of the Chinese Academy of Sciences have cooperated closely and complemented each other's advantages to carry out the mutagenesis breeding of
japonica rice radiated by high-energy heavy ion beams (C).
。 With the strong support of the state, the Chinese Academy of Sciences and local provinces and cities and other projects, after more than 10 years of joint research, the project team has overcome the key core technology of high-energy heavy ion beam carbon (C) radiation northern japonica rice mutagenesis breeding, built a high-energy heavy ion beam radiation northern japonica rice "less and fine" mutagenic breeding technology system, broke through the traditional breeding commonly found in the traditional breeding of large amount of preparation combination, large early generation group, large selection workload, long breeding cycle and other defects, and successfully opened up a new way of light and efficient northern japonica rice breeding.
It has promoted the scientific and technological progress
of japonica rice breeding technology in northern China.

The successful approval of the series of varieties marks the great success
of the mutagenesis breeding technology and method of high-energy heavy ion beam radiation northern japonica rice pioneered by the team in China.
In the next step, we will work closely with seed companies to increase the demonstration and promotion of new rice varieties, accelerate the transformation of new varieties of achievements, and increase farmers' income and enterprise efficiency
