3197A是我国杂交高梁生产上广泛应用的雄性不育系,这个雄性不育性状是细胞质细胞核共同作用的结果。因此,它既可以找到保持系,又可找到恢复系,实现三系配套。为了生产上的需要,已选育了许多高梁雄性不育系,但这些不育系的细胞质不育基因都是来源于3197A。所以,目前高梁的不育型同属3197A型号,就是说,对3197A是保持型的,那么对 3197A is a male sterile line widely used in the production of hybrid sorghum in China. The male sterility trait is the result of the synergy of the cytoplasmic nucleus. Therefore, it can not only find the maintenance department, but also find the recovery department and achieve the three-departmental support. For the sake of production, many sorghum male sterile lines have been selected, but the cytoplasmic male sterility genes of these CMS lines are all derived from 3197A. Therefore, the sorghum sorghum is currently the same type of 3197A, that is, to maintain the type 3197A, then
