以花粉可育率和自然结实率为指标，对红莲型细胞质雄性不育系丛广４１ Ａ 与其恢复系配制的 Ｆ１ 、 Ｆ２ 、 Ｂ Ｃ１ 和 Ｂ Ｃ２ 等世代的育性表现进行了调查，结果表明，红莲型细胞质雄性不育系丛广４１ Ａ 属配子体不育，其不育性受一对隐性核主基因和不育细胞质共同控制，其核不育基因与珍汕 ９７ Ａ 不等位 其恢复性受显性单基因控制，密阳 ２３ 有一对强恢复基因，珍汕 ９７ 有一对弱恢复基因

Inheritance of `HL' type cytoplasmic male sterility (CMS) and its fertility restoration in rice (Oryza sativa L.) was studied using pollen fertility and seed setting rate as criteria of fertility. By utilizing `HL' type CMS line Congguang41A in combination with four restorers, the following generations: P1, P2, F1 (A×R), BC1 (F1×B), BC2 (A×F1), F2 were obtained. Results indicated that the male sterility of Congguang41A was gameophytic and was controlled by the interaction of a sterile cytoplasm with one pair of recessive nuclear genes. The comparison of restoring-maintaining ...
