On June 28, it was the 11th day that three astronauts set off on Shenzhou 12 and entered the core module of the space station
Chinese people who value farming have been exploring the mysteries of space farming
"It has been 34 years since China first launched the return-type satellite space carrying of rice and other crops seeds in 1987.
Aerospace mutagenesis + breeding technology, creating new germplasm and breeding new varieties
Space breeding, also known as space mutation breeding or space mutation breeding, is to bring animal and plant microbial germplasm to extraterrestrial space through spacecraft such as returnable satellites, induce mutation and mutation, and breed new varieties on the ground after returning.
"China is a big country in mutagenesis breeding.
China is a big agricultural country, but the richness of varieties is still far behind the production demand.
"Almost every launch of a spacecraft carries seeds, and this time Shenzhou 12 also carries seeds.
Nearly 200 new varieties of excellent germplasm approved at or above the provincial level have been cultivated
Since 2009, the National Plant Space Breeding Engineering Technology Research Center approved by the Ministry of Science and Technology and the Space Breeding Research Center established by the Chinese Academy of Agricultural Sciences have focused on the mechanism of space mutation, creation, evaluation and utilization of new germplasm resources for space mutation, new quality and supporting engineering technology and industrialization and other fields to actively and orderly work
In 2018, 14 units including the Chinese Academy of Agricultural Sciences and China Agricultural University initiated the establishment of the Space Breeding Industry Innovation Alliance, which aims to enhance the germplasm innovation of space breeding, promote the transformation of space breeding technology achievements, and promote its industrialization
At present, at least 130 research units are involved in carrying and space breeding, and they have established space breeding and breeding bases in Gansu, Beijing, Hainan and other places
"As of 2018, 42 provincial and national rice varieties have been bred using spaceflight mutation breeding technology
