植物体自然突变有可能出现优良个体.人为地采取物理与化学的措施同样可以诱发植物体发生变异并进一步选择培育优良品种.这就是“果树诱变育种”.果树等无性繁殖植物在诱变育种中不像以种子繁殖的作物那样,突变了的细胞组织一定要参与形成种胚时才能在后代中重新表现出突变性状,而只要将突变的细胞组织采取无性繁殖的方式,便可以把突变很快地固定于后代 Natural mutation of plants may appear good individuals.Artificial and physical measures to take the same can induce plant mutation and further selection and breeding of fine varieties.This is “fruit tree mutation breeding.” Fruit trees and other clonal plants in mutagenic breeding Unlike in seed breeding crops, mutated cells must be involved in the formation of embryos in the offspring in the re-show the mutant traits, and as long as the mutation of the cells and tissues to adopt asexual reproduction, we can put the mutation is very Quickly fixed to future generations
