辐射育种就是人为地利用具有辐射能的一些物质诱导生物发生遗传性的变异,然后据据育种目标进行选择,来培育新的物种或品种。从1927年缪勒(Muller)用果蝇作生物试验,发现 X 射线有诱变作用以来,随着农业生产的不断发展,对育种工作也提出了许多新的要求。不仅要求人们寻找快速而有效的育种途径,而且要求采用新的技术方法创造优良的变异,培 Radiation breeding is the artificial use of some substances with radiant energy to induce biological genetic variation, and then according to breeding objectives to choose, to cultivate new species or varieties. Since Muller's biological experiment with fruit flies in 1927 found that mutagenesis of X-rays has taken place, with the continuous development of agricultural production, many new requirements have also been put forward for breeding work. Not only requires people to find fast and effective ways of breeding, but also requires the use of new technical methods to create good variation, training
