摘要： 以辣(甜)椒细胞质雄性不育系21A、8A和9个不同基因型的辣(甜)椒恢复系为材料，研究其不育恢复基因的遗传。结果表明，匈804、LS7、湘紫、洛紫、SI201、转育R甜和转育R辣均能完全恢复21A和8A的不育性，具有1对显性恢复基因，湘紫、洛紫和转育R辣的恢复基因为等位基因，与SI201恢复基因不等位。南昌92-1和洛甜2号对21A和8A的不育性只能部分恢复且恢复率存在差异。利用辣(甜)椒细胞质雄性不育系21A、延A、8A与138个辣(甜)椒自交系测配414个杂交组合，其中有102个组合育性完全恢复，占24.6%；有146个组合育性分离，占35.3%；有166个组合育性完全不恢复，占40.1%。在恢复的组合中，辣椒恢复系占82.4%，甜椒恢复系仅占17.6%，表明恢复基因的分布主要存在于辣椒材料中，甜椒材料相对较少。

Abstract: The hot pepper CMS 21A, sweet pepper CMS 8A and 9 different genotype fertility restoring lines were used to study the inheritance of fertility restoring genes. The results showed that Xiong 804, LS7, Xiangzi, Luozi, SI201, translated R-gene sweet pepper and hot pepper inbreds were fully restoring lines to CMS 21A and 8A and possessed a pair of dominate restoring genes. The restoring genes in Xiangzi, Luozi and translated R-gene hot pepper were allele, but non-allele in SI201. Nanchang 92-1 and Luotian No.2 were partial restoring lines to CMS 21A and 8A and there were differences in the fertility restoring rates. 414 combinations were made between CMS lines (21A, YanA and 8A) and 138 inbreds (hot and sweet pepper). Fertilities in 102 of them were fully restored, 146 partially restored and 166 unrestored. Among the fully restored combinations, 82.4% were hot pepper restoring lines, but only 17.6% were the sweet pepper restoring lines. It suggested that the restoring genes were mainly distributed in the hot pepper (inbreds).
