What is space breeding? What are the benefits of space breeding?

Space breeding, also known as space mutation breeding, is a new breeding technology that sends crop seeds or mutagenic materials into space through recoverable satellites or high-altitude balloons, mutates the seeds by using special environment in space, and then returns to the ground to cultivate new crop varieties.

Space breeding can shorten the breeding cycle. According to experts, normal agricultural breeding generally takes eight years, and space breeding can shorten the time by half. However, after being brought back from space, it must be planted on the ground for four generations to cultivate a variety with stable performance.

Space breeding is a new interdisciplinary subject of 1, involving many fields, such as space technology, radiation technology, biotechnology and so on. And it is not very mature and perfect. After all, there is little space flight, mainly rice and wheat. Because China is a big agricultural country with 1, space breeding technology has been paid attention to. Although China is not 1 for aerospace technology, it should be 1 for aerospace agricultural breeding. Generally, it takes 8 years for hybrid technology in conventional breeding to obtain new varieties, and space breeding can shorten the time by half. After being brought back from space, it must be cultivated on the ground for no less than 4 generations. Space breeding is 1 a good way to shorten the breeding cycle.
