辐射育种是近三十多年蓬勃发展起来的一种育种方法。它是利用高能射线辐照生物或生物的某一器官,使其发生突变,通过人工定向选择,培育出新的优良品种或物种。辐射育种是和平利用原子能的一个重要的领域。国外自1927年在植物育种上应用辐射诱变方法,一直到二次世界大战结束的二十多年,是辐射育种实践与理论的酝酿准备阶 Radiation breeding is a breeding method that has flourished in recent thirty years. It is the use of high-energy rays to irradiate an organism or organism to make its mutation, by artificial selection, to breed new fine varieties or species. Radiation breeding is an important area for the peaceful use of atomic energy. The application of radiation mutagenesis on plant breeding since 1927 in foreign countries until the end of World War II more than 20 years is the brewing preparation of radiation breeding practice and theory
