离子注入诱变法选育烟草新品系研究

On Breeded New Tobacco Strain by Inducing Mutation with Ion Implantation

用氮离子注入处理烟草ＳｐｅｉｇｈｔＧ８０干种子产生突变，在Ｌ２代选择性状优良的变异单株，其中一株系Ｌ６～２（氮离子处理剂量脉冲２０次，能量３０Ｋｅｖ的后代）其形态特征与亲本存在着明显的差异，开白花（亲本花色粉红），叶较宽，经连续六年选择鉴定，选育出一个性状稳定。

Dry seeds of Speight G 80,which treated with N + ion implantation,produced mutant.The individual plant,which expressed fine properties,were selected in L 2 generation,in which one individual plant were deference with its parents.By six years selection,a new strain(L6 2)that possess steady properties,high quality,disease resistant had been breeded.
