应用化学诱变剂育种,其诱发某一性状突变的效率比X射线高3—5倍。化学诱变剂对诱发植物的某一性状变异比杂交育种更有效、更简便,后代性状稳定也较快。因此,引起了育种工作者的重视。七十年代后,国内外学者利用化学诱变剂处理种子、无性繁殖器官、卵、合子或原胚都取得了较理想的结果,而且选育了一批农作物新品种。 Application of chemical mutagen breeding, the mutation induced by a certain efficiency than X-ray high 3-5 times. Chemical mutagens induce more variation in a certain trait in plants than hybrid breeding, and the traits of offspring are stable and fast. Therefore, it attracted the attention of breeding workers. Seventies, domestic and foreign scholars using chemical mutagen treatment of seeds, asexual reproduction organs, eggs, zygotes or embryos have achieved better results, and bred a number of new crop varieties.
