随着育种工作的发展,辐射育种愈来愈被人们所重视和利用,诱变手段亦有新的发展。然而如何正确掌握变异世代,提高有益突变频率,扩大变异谱,提高诱变育种效果等是诱变育种工作中需进一步解决的问题。为此,我们作了不同辐照源和辐照方法及不同世代的诱变效应研究,为诱变育种进一步提供依据。 With the development of breeding work, radiation breeding is more and more valued and utilized by people, and there are also new developments in mutagenesis methods. However, how to correctly grasp the generation of mutation, increase the frequency of beneficial mutation, expand the mutation spectrum and improve the effect of mutation breeding are the problems to be further solved in mutagenesis breeding. To this end, we made different irradiation sources and irradiation methods and mutagenesis effects of different generations, to provide further evidence for mutation breeding.
