烤烟离子诱变后代筛选材料的性状鉴定

Character identification of the materials that screened form the N^+ ion implantation progeny

对 N离子束诱变处理的烤烟 NC89和 K32 6后代 (已经过两代筛选 )变异材料 M1 和 M2 进行了性状鉴定。结果表明 ,M1 和 M2 在主要植物学及农艺性状上发生了较多的优良稳定变异 ,M1 株型优化 ,M2 产量提高 ,M1 、M2 烟碱含量、钾氯比均优于对照 。

The character identification of M 1 and M 2 were studied in the field (M 1 and M 2 were mutation progeny of NC89 and K326 that were treated by N\++ ion beam).The results showed that M 1 and M 2 had excellent and steady variations of botany characters and agronomical characters.The plant type of M 1 has been improved in shape,the yield of M 2 has been raised. Either of them was better than CK in the nicotine content and the K 2O/Cl ratio.
