輻射选种在世界各国已取得了很多成就。其主要特点是可能在具有最复杂的有价值性狀综合的优良品种上,只改变其一个性狀,而不触及其它性状;能选育出其它选种方法所不能或不易选出的品种;能引起大量的突变,增加选擇的机会;能使野生类型的染色体片断发生易位,使其个别特性傳给栽培品种。不同种类的射线及不同的引变剂量,对植物有不同的引变作用,而植物不同发育阶段也具有不同的輻射敏感性。外界因素能影响引变作用。
Radiation selection has made a lot of achievements in various countries in the world. Its main feature is that it is possible to change only one trait in the finest breed with the most complicated comprehensive traits of the valuable traits without touching other traits; to breed breeds that can not or not be easily selected by other breeding methods; to cause A large number of mutations increase the chance of selection; the translocation of the wild-type chromosomal segments can be made to pass on their individual traits to cultivars. Different types of radiation and different doses lead to different functions of plants, and plants have different radiation sensitivity at different developmental stages. External factors can affect the lead role.
