诱发突变育种早在本世纪二十年代就开始进行实验。近年来世界上和我国利用诱变育种培育出了一些新的果树品种和得到许多有价值的突变类型。实践证明,这种方法用于处理果树接穗,对于改良品种一、二个不良性状而保持优良性状基本不变,具有独特的效果,并可大大缩短育种年限。我所早在1964年就开展了这项研究。由于各种原因,这项工作的连续性和系统 Induced mutation breeding early in the twentieth century began experiments. In recent years, the world and China have used mutagenesis to breed some new fruit tree breeds and get many valuable mutation types. Practice has proved that this method is used to deal with fruit scion, to improve the varieties of one or two bad traits and maintain good traits basically the same, has a unique effect, and can greatly shorten the breeding time. I started the study as early as 1964. The continuity and system of this work for various reasons
