Heavy ion-radiation breeding technology gives the glycerine industry productivity -
"ten-north" project ecological rehabilitation injected "technologies"
In 2025, the grassland technology promotion station of gansu province, in collaboration with the institute of modern physics of the chinese academy of sciences, focused on specialty varieties such as red soybean grass and cattail grass, targeted to enhance critical conditions such as drought resistance, salin resistance and high productivity, and explored indigenous techniques for the breeding of heavy ion radiation on grass。
This cutting-edge technology of heavy ion beams, which depends on the country's large scientific apparatus, and the deep integration of local ecological protection of grassland needs, is a scientific and technological upgrading of native grassland, providing a customized grassland solution to the problem of inadequate supply of high-quality grassland in the “thir north” engineering area and to the construction of an ecological safety barrier in the north of the country。
Front-line technology enabling breeding revolutions
"it's the leap of physical frontier technology to grassland productivity." the director of the institute of recent physics of the chinese academy of sciences described the technology used to breed heavy ion radiation, based on the country's large scientific apparatus, to accelerate heavy ion, such as carbon and thorium, to near light speeds, so that precision could be applied to the seed embryo core, increasing mutagenic efficiency by 10 to 100 times, with a wide range of mutations and a short stabilization cycle, which is a revolutionary technology that has been hailed internationally as “one-point breeding”。

At present, the institute has successfully developed radioactive breeds on crops such as rice, maize and flowers, and has developed a well-established technical system and extensive practical experience, providing a solid foundation for the application of this technology in grass breeding。
In response to the need for ecological restoration in gansu province and for construction of the “tri-north” project, the grass-based resource innovation and grass-breeding team customizes the irradiation programme for the three indigenous good varieties of grass-red red soybean weeds, cattails and red leaves. “we will aim to improve the critical state of drought resistance, salinization and high productivity, based on preserving the original advantages of the varieties, to make the native grass-breeding more suitable for the harsh environment of the three northern regions.” the head of the grassland technology promotion station in gansu province stated that the target was a pro-breeding approach that accurately matched the gansu's diverse ecological characteristics。
Field test boosts good mutation screening select
Radiation breeding is well under way, thanks to a well-established system of resource protection for grasslands. Since 2020, the gansu forest and grass office has been gradually refining its system of resource security around the needs for research and precision evaluation of grassland characteristics in different ecoregions. Five typical ecological areas, such as the oasis irrigation area of the western corridor, the desert area of the western corridor of the river, the yellow highland area of the central yoghurt of the river, the high humid area of gannan, the high humid area of the cyanide highlands and the high area of the cyanide highlands, have been set up in a scientific configuration of eight grassland resource nurseries and 16 regional testing stations for grassland varieties, and a network of grassland resource collection, conservation, observation and evaluation systems covering diverse habitats has provided a strong guarantee for the study of the sexual diversity of radioactive grasslands in different regions。
At present, the “grass red 1” radiation mutagenic material for red bean herbs has been evaluated in the provincial grass-grass resource nurseries of the faculty of agricultural sciences of the city of deutsche. The core indicators of seeding, resistance and growth patterns are systematically monitored through multi-dose gradient radiation treatment, and quality seed resources of breeding value are screened. At the same time, the red herbs reserve is being synchronized with cattails and red-leaved irradiated seeding materials. The two special grasses adapted to the high humid areas are being tested for yield and quality enhancement mutagenicity to fill the gaps in the supply of high-quality grasses in the high cold areas。
"we've developed irradiation treatment - seeding measurements - multigeneration selection' a complete technological system, based on the m1tds target-screening of rice mutagenic breeds, to ensure a stable genetic quality. “technologists described the entry of the first m1 generation material into the critical observation period and the better-than-anticipated rate and early growth posture of some processing teams, which provided a good basis for subsequent m2 generation screening. In stable seed nurseries, scientists have also accelerated the process of genetic stabilization and improvement of varieties of good mutations through technical means such as artificial pollination。
The target is the breeding of herbs exclusively for the three north project
As a landmark project in the country's ecological construction, the project's savannah area covers approximately 2. 2 billion acres, or 55 per cent of the country's savannah area, and is an important ecological safety barrier in the north of the country. As a key area for the construction of the three north project, gansu is an ecological barrier to the southward movement of the three deserts, but the problem of the poor adaptation and high cost of imported grasslands is highlighted by the lack of good soil and grassland for degradation and sandy pasture restoration。
This time, heavy ion-radiation breeds were devoted to the development of the “tri-north” species of grass, which are of the highest quality, deep roots, drought-resistant and salin-resistant, and to the decomposition of the poor suitability and supply of grasslands in the engineering areas。
A seed, plowing an industry. This application of ion-radiation breeding technology will promote grassland development from traditional experience to precision breeding. Since the fourteenth five-year plan, 43 grass varieties have been validated at gansu provincial level, and six original breeding sites have been established。
As a next step, the team will continue to explore the model of “scientific institutions + cooperatives + enterprises” for the integration of reproduction, accelerating the pace of good mutation screening and species innovation, and giving grasslands after “technologies” their roots in ecological restoration. “the ecological safety barrier in the north must be constructed while boosting the incomes of farmers and pastoralists to achieve both ecological and economic benefits.” according to the head of the grasslands promotion station in gansu province, the implementation of the heavy ion-radiation seeding project will provide sustainable grassland support for the ecological restoration of the san-nord project and provide experience in the promotion of grasslands in the country.
