摘　　要：本研究以甜菜杂交种为处理材料,用N+离子作为诱变源,以35kev的能量,分别以40次、60次脉冲,注入剂量4×1016N+/cm2、6×1016N+/cm2进行激发诱变,变异显著,部分处理材料含糖率、产量有明显提高,为其它作物杂交种处理获得当代效应提供了有益参考。By using the crossbreed of sugar cabage as a treatment material and N+ ion as an inducing source, we carry out the experiments of stimulation and inducement.The dosage are implanted of 4×10^(16)N+/cm^2 and 6×10^(16)N+/cm^2 with the energy of 35kev in the pulse of 40 and 60 times respectively.As a result variation of the crossbreeds are remarkableespecially sugar content and output of the part are greatly improvedThe finding provides the crossbreeds of other crops an useful reference to obtain the current effect.
