利用各种射线和化学诱变剂诱发植物遗传变异,具有诱发突变,促进遗传基因重新组合,提高突变频率,扩大变异谱等特点。能够在较短时间内获得有利用价值的突变体,育成优良品种直接利用或作为种质资源间接利用,还可以解决育种的某些特殊问题。突变育种是一种有效的育种途径。
The use of a variety of ray and chemical mutagens induced plant genetic variation, with induced mutation, promote gene recombination, increase the frequency of mutation, expand the spectrum of variation and so on. Mutants with useful value can be obtained within a relatively short period of time, bred directly into superior varieties or used indirectly as germplasm resources, and some special problems of breeding can also be solved. Mutation breeding is an effective breeding method.
