Moreover, after mutagenesis, the plant is subjected to somatic selection, namely, the mutant cell and the non-mutant cell compete in the growth and development process, the initial mitosis of the mutant cell is usually inhibited or delayed due to the physiological damage or chromosome damage of the mutant cell caused by radiation, so that the normal cell is always dominant, and in the top dominant plant, the mutant cell may not exist in the growth cone at the upper part of the branch, the plant is recovered to be normal, the mutant character disappears, and the homogeneous mutant with stable character is difficult to obtain.
