航天育种也称太空诱变育种,它是一门近年来迅速发展起来的,把航天技术、生物技术和传统育种技术结合在一起的高科技学科。其方法是将植物的种子或试管培育的细胞、组织、小苗,通过返回式航天器的太空搭载,利用太空高真空、微重力、强辐射和超洁净的特殊条件,使其遗传物质(染色体、基因)发生在地面条件下不能获得的诱变效果。回到地面后,再进一步用传统育种方法选育新的品种或育
Space breeding is also called space mutation breeding. It is a high-tech subject that has rapidly developed in recent years and integrated space technology, biotechnology and traditional breeding technology. The method comprises the following steps: plant seeds, test-tube-growing cells, tissues and seedlings are transported in the space of a spacecraft, utilizing special conditions of high vacuum in space, microgravity, strong radiation and ultra-cleanliness to make their genetic material (chromosomes, Gene) occurs mutagenic effects that can not be obtained under the surface conditions. Back to the ground, and then further use of traditional breeding methods breeding new varieties or breeding
