A:太空育种是指通过返回式卫星等航天器,将农作物的种子送到太空,利用太空中一些特殊的条件,主要是高能射线的轰击,使得种子的基因发生突变,待返回地球后,再经过繁难的培育筛选出良种的育种方法。太空育种属于诱变育种,如《科学世界》2016年第2期“转基因”专辑所介绍的那样,诱变育种增加了突变的可能 A: In space breeding, seeds of crops are sent to space by means of spacecraft such as return satellites. Utilizing some special conditions in space, mainly the bombardment of high-energy radiation, the seed gene mutation occurs. After returning to Earth, After a difficult breeding screening of breeding methods. Space breeding is mutagenic breeding, as described in the “World of Science” issue No. 2, 2016 “Transgenic” album, mutation breeding may increase the possibility of mutation
