辐射育种做为一种有效的育种手段已经广泛应用,培育出了一大批有价值的新品种和突变体。在辐射源中钻源具有价格便宜,使用方便的特点,是国内外辐射育种中应用最广的一种。而γ射线是一种当代生理损伤很强的电离辐射,在一定剂量范围内,诱变频率随着剂量的增加而增加,但是剂量越高致死效应越强,得不到一定数量的后代群体,影响了选择效果。提高照射剂量,降低当代
Radiation breeding as an effective means of breeding has been widely used, cultivating a large number of valuable new varieties and mutants. In the radiation source drilling source has the characteristics of cheap, easy to use, radiation breeding at home and abroad is the most widely used. Γ-ray is a kind of ionizing radiation with strong physiological damage. In a certain dose range, the mutagenic frequency increases with the increase of dose, but the higher the dose is, the stronger the lethal effect is, and a certain amount of offspring can not be obtained. Affect the selection effect. Increase exposure dose and reduce contemporary
