China has planted 12000 seeds brought back from space

The mutation caused by exposure to cosmic radiation and microgravity may help to create new and excellent varieties.

Chinese researchers began to plant 12000 seeds, including alfalfa, oats and mushrooms, which were placed in the Shenzhou 13 manned spacecraft for six months and brought back to earth on February 16, 2002. four

These seeds were carefully selected by many research institutions last year. Space transmission refers to the process of exposing seeds to radiation and microgravity, causing gene mutations, and then returning to earth to create new species.

In the basic technology evaluation stage of the China space station project, space breeding experiments are carried out for each flight. Thousands of seeds and microorganisms from 88 organizations have flown into space aboard Shenzhou 12 and Shenzhou 13.

The team of m-grass, an engineering company in Inner Mongolia Autonomous Region, tested six kinds of grass on Shenzhou 13. This is the second time that the company has sent seeds into space after the lunar probe "often" collected mutant grass seeds. E 5 in 2020. According to liusiyang, researcher m-grass, through more careful selection and planting process, excellent grass varieties will be used to restore the ecosystem and build the urban landscape.

On October 16, 2021, the Shenzhou 13 mission brought three astronauts to the core module of the Chinese space station for a six-month stay. This is the longest stay in the space station in China's manned space program.
