辐射诱变是生物育种的重要手段之一,其主要特点是可以诱发基因突变,创造新的基因型和突变性状。但辐射诱发的突变具有随机性、嵌合性和单细胞性质,大部分突变不能显现便伴随着“二倍体选择”和个体衰老等生物学过程而消失。为此,我们在育种的过程中,把组织培养手段纳入辐射育种程 Radiation mutation is one of the important means of biological breeding. Its main feature is that it can induce gene mutation and create new genotype and mutation trait. Radiation-induced mutations are random, chimeric and unicellular in nature, and most of the mutations can not be displayed with the disappearance of biological processes such as “diploid selection” and aging. For this reason, we incorporated the means of tissue culture into the radiation breeding program during breeding
