    magical changes that will occur when you return to Earth from a "space trip" with a spacecraft? This issue has been a matter of great concern to the general public. Since the implementation of China's manned space program, in order to give full play to the comprehensive benefits of the project, serve the community, benefit the people's livelihood, since the Shenzhou-1 spacecraft began, China's manned space engineering office in the engineering flight test, the use of Shenzhou spacecraft, space laboratory and a new generation of manned spacecraft test ship and other aircraft resources, organized a series of crop seeds and plant materials space-mounted mutation experiments, after many years of ground breeding and scientific research, up to now, a total of more than 200 species of new species through the ministry. It is estimated that the direct economic scale of space breeding creation exceeds 200 billion yuan.August 29th, a symposium on grass space breeding was held in Lanzhou, and representatives of the China Manned Space Engineering Office handed over the grass seeds and public certificates carried by a new generation of manned spacecraft to the Lanzhou Institute of Livestock and Veterinary Medicine of China's agriculture
    The new generation manned spacecraft test ship, a newly developed spacecraft for China's space station operations and future manned lunar exploration missions, was launched into orbit by the Long March V B carrier rocket at the Wenchang Space Launch Site on May 5 this year and successfully returned to Earth on May 8. During the meeting, experts from all parties held heated discussions and exchanged experiences and achievements in space breeding.
    in many new varieties, after the Shenzhou 3 spacecraft carried the selection of the breeding of the Zhongtian No. 1 alfalfa grass species has attracted much attention. Yang Hongshan, chief expert of the anti-reverse grazing and utilization team of Lanzhou Institute of Livestock and Veterinary Medicine, said: "After
    16 years of breeding research, Zhongtian No. 1 alfalfa grass species has been approved by the National Grass Variety
    in 2018

    Space breeding is a new breeding method combining space technology, biotechnology and agricultural breeding technology, and under the combined action of space environmental factors such as cosmic high-energy particle radiation and microgravity, space mutagenogenics produce variations at the genome level, and after returning to the ground, they are selected by at least 4 generations of ground-based breeding, screening out new materials and new species with new traits, and finally cultivating new strains with genetic stability and good quality. Over the years, space breeding in China's food security and ecological environment construction and many other fields have made important contributions to the cultivation of wheat, rice, corn, pumpkin, soybeans, cotton and tomatoes, peppers and other horticultural crops of new varieties of cumulative planting and promotion area of more than 2.4 million hectares, it is estimated that space breeding to create a direct economic scale of more than 200 billion yuan, become one of the effective ways to rapidly cultivate good varieties of crops.
    experts said that after many years of practical verification, whether it is the genomic level, or the level of oscic genetics, space breeding has created rare or never-before-seen new variants and traits in nature, enriched the genetic diversity of species resources, produced a large number of beneficial new mutations, created a number of genetic resources with excellent traits, some important agro-artistic traits have a breakthrough impact.fact, space mutation in space breeding belongs to radiation mutation in physical mutation, and physical radiation mutation breeding has a long history, nearly a hundred years since 1928. To date, more than 3,000 new crop varieties (covering 240 crops in more than 70 countries) have been officially approved and used for commercial production, according to the United Nations Food and Agriculture Organization and the International Atomic Energy Agency.
    the 1960s, the United States, the Soviet Union, Canada, Japan, Finland, Australia and Brazil have been carrying out space biology research and space breeding practices. For example, the United States "Giant Cotton 1" insect-resistant cotton is obtained by the space radiation variation of a new variety of anti-worm cotton ultra-high yield, the Soviet Union carried cotton and eucalyptus trees have long been planted in Large areas of Kazakhstan.
    china's space breeding began in the 1980s. Seeds were originally carried to detect the genetic effects of the space environment on plants. Studies have shown that these seeds have undergone a series of unexpected mutations: radish seed seedlings that experience the spatial environment thrive, and garlic seeds from the upper world grow up to 150 grams of garlic. Therefore, China's space breeding research is gradually on the right track, space breeding disciplines have been continuously developed.
    the implementation of China's manned space engineering self-reliance project, China's manned space engineering office has planned and implemented a series of space breeding experimental projects. Since the beginning of the Shenzhou-1 mission in 1999, using the unique advantages of manned spaceflight and the resources of manned spacecraft, more than 100 species and more than 5000 species of crop seeds and plant materials have been organized and carried out in space-mounted mutation experiments. In addition to the field of crop and forest breeding, it also carries experimental loads of space biology and carries out space biology research such as the growth and development of higher plant space environment.
    In 2011, shenzhou 8 mission organization carried out the "tomato test tube seedling space flowering strong" experiment, carrying a total of 8 tomato buds, to achieve the results of plant flowering in the space environment, to verify the feasibility of higher plants in the space environment flowering strong. Launched in 2016, Tiangong-2 Space Laboratory carried out advanced plant culture experiments, the first "seed-to-seed" space plant life cycle culture experiment in China, and the first real-time image of green fluorescent protein controlled by the amoeba flowering gene promoter in the space environment, providing a useful reference for the future establishment of a plant-based space life ecosystem.more than 30 years of research and application, the results of space breeding has been quietly integrated into all aspects of people's lives. This technology not only promotes the improvement of crops, but will also be used in food processing, wine brewing, biopharmaceuticals, oil exploration and many other directions, resulting in outstanding economic benefits.
    China's pasture space breeding is still in the initial stage, mainly focused on the selection of grasshopper varieties research, there is still a broad space for development in the future, has been successfully cultivated "Zhongtian No. 1 alfalfa", "Agriculture No. 14 alfalfa" and other national and provincial-level pasture varieties, promoting the development of grass plant space breeding research, has been promoted throughout the country to plant more than 250,000 mu. "Zhongtian No. 1 alfalfa" species of high-quality, prolific characteristics outstanding, hay national test per acre up to 1789.9 kg, crude protein content of an average of 20.8%, reached the national level of China's hay bale grading standards, effectively solve the domestic high-quality high-product species, the rapid degradation of imported varieties abroad and other issues.
    According to the plan of China's manned space program, the Chinese space station is expected to be built and put into orbit by 2022, and in the future, astronauts will be stationed in orbit for a long time to carry out scientific experimental research and technical experiments. As a national space laboratory, the space station can provide more and better experimental conditions and opportunities for scientists in more fields to carry out space science research, and all kinds of research results, including space breeding, will certainly benefit the lives of ordinary people more.
