把花粉育性划分为可育、染败、圆败和典败四种类型,对三种不同细胞质来源的四个水稻雄性不育系的质核互作雄性不育性进行基因分析。结果表明,野败珍汕97A、野败二九矮4A、冈比亚卡二九矮7A 和毛早壳八四早8A 的质核互作雄性不育性均由两对隐性育性恢复基因 rf_1 rf_1 rf_2 rf_2控制,属孢子体不育类型。IR24具有相应的两对显性育性恢复基因 Rf_1 Rf_1 Rf_2 Rf_2。恢复基因的显性作用是不完全的,具剂量效应。具1Rf 基因型的植株不一定能产生可育花粉。具1Rf 基因型的全不育株率因不同组合而异。
Pollen fertility was divided into four types: fertile, stained, round and defeat. The genetic analysis of the male sterility of four nuclear male sterility lines derived from three different cytoplasms was carried out. The results showed that the male sterility of nucleus and nucleus of wild Zhenshan97A, wild dumb19A4A, GambiankaⅡ9A and 7A were respectively controlled by two pairs of recessive fertility restorer rf_1 rf_1 rf_2 rf_2 control, is a sporozoite type of infertility. IR24 had the corresponding two pairs of dominant fertility restorer genes Rf_1 Rf_1 Rf_2 Rf_2. The dominant role of the recovery gene is incomplete, with a dose-response. Plants with the 1Rf genotype do not necessarily produce fertile pollen. The rate of all-sterile plants with the 1Rf genotype varies with different combinations.
