摘 要 ：高粱细胞质雄性不育系3197A(以下简称3A)柱头用恢复系5号(以下简称恢5)外源 DNA 处理后,授以保持系3197B(以下简称3B)花粉。F_1代部分植株可部分结实。F_2代分离到完全可育并对3A 雄性不育类型表现恢复的3197A(以下简称 F_3A),现已稳定遗传到 F_6代。除育性的改变外。F_(3A)保持了不育系3A的基本特征特性。以上试验结果初步表
Abstract:This experiment on sorghum was started in 1979.The seedling DNAof restorer No.5 was smirched on the stigma of 3197A(male sterileplants)and then pollinated with fresh pollens of 3197B(maintainer).Seeds and their offsprings were obtained,these plants were very similarto 3197A(except leaf type),but the
