Three varieties of upland cotton（Gossypium hirsutum L. ）,which are G-20,N-156 and NK-20,were induced by three methods including EMS chemical mutation,14N heavy ions implantation and 60Coγ-rays radiation to select botany character,yield trait and fiber quality trait mutants.
采用EMS化学诱变、14N重离子注入及60Coγ射线辐照3种诱变方式处理冀棉20、农大156和农抗2号棉花品种,利用四分位法和系谱选择法筛选到植物学性状、产量性状和纤维品质性状突变体并采用SSR标记对突变体进行分子水平鉴定。

9.初步建立了白桦愈伤组织化学诱变技术:在高浓度EMS短时间处理和低浓度EMS长时间处理条件下可获得到叶柄、叶片愈伤组织的半致死剂量:通过观察半致死剂量下愈伤组织细胞的染色体数目发现,诱变后细胞中单倍体、非整倍体及多倍体细胞比例均显著高于对照,总变异率由诱变前60%提高到89.93%,这说明EMS对白桦愈伤组织的诱变作用是显著的。
