叙述了60Co-γ射线辐射苦荞麦籽粒M2至M5代各变异单株后代籽粒粒形、粒色、刺的有无及植株茎色等性状不易稳定,存在连续多代变异现象,表明辐射诱变后代变异性状稳定性差,诱变育种具有可行性和困难性。 The grain shape, grain color, spines and stem color of the offspring of M2 to M5 generations of 60Co-γ-ray irradiated grain were not stable, and there were many successive generations of variation, which indicated that the radiation mutagenesis The stability of the offspring variation traits is poor, mutagenesis breeding is feasible and difficult.
