在早先利用穗茎注射法将大黍(Panicum maximum Jacq)基因组DNA导入杂交籼稻恢复系桂99获得高频雌性不育突变株系FSV1与其遗传、胚胎特性研究基础上,对FSV1雌性不育性进行了进一步的遗传分析,并对控制雌不育性的基因进行了初步定位。结果表明,其雌不育性系1对隐性基因(fsv1)控制,该基因被初步定位于第9号染色体长臂端261 kb的范围内。对FSV1雌不育性形成的分子机制及其应用途径进行了讨论。 Based on the previous studies on the genetic and embryo characteristics of the high frequency female sterile mutant FSV1 by introducing panicum maximum Jacq genomic DNA into the indica rice restorer line Gui 99 by ear-stem injection, the female sterility of FSV1 Further genetic analysis was carried out, and the genes controlling female sterility were initially located. The results showed that the male sterility line 1 was controlled by the recessive gene fsv1. The gene was initially located in the region of 261 kb on the long arm of chromosome 9. The molecular mechanism of FSV1 female sterility and its application are discussed.
