Somaclonal Variation of Cytoplasmic Male Sterile Lines with Wild Rice Cytoplasm I. The Types of Somaclonal Variation from IR66707A & IR69700A (English)
水稻雄性不育系IR66707A及IR69700A来自国际水稻所(IRRI),它们的不育性只能被保持而不能被恢复,属于胞质型雄性不育.以这两个不育系以及它们与正常品种的杂种F1为供体,经离体培养,共获得了136个体细胞克隆.在R1代中发现了三个类型的突变或变异,即:可育突变、雄性不育和雌雄性均不育的变异.第一类型的可育突变有两例,其R2的可育与不可育(出现分离)之比为3:],证实为显性单基因突变.第二类型的雄性不育又可分为两种:第一种是不育性可被恢复的,与供体不育系完全不同,其中一部分克隆的不育… (Chinese)
