The invention belongs to the technical field of vegetable crop breeding, and provides a method for simultaneously transforming a cytoplasmic-nuclear interaction type restorer line (the genotype is N (RfRf)) into a male sterile line (the genotype is S (rfrf)) and a maintainer line (the genotype is N (rfrf)) with the same agronomic traits. Through the methods of hybridization, test cross, backcross, selfing and the like of multiple generations for many years, the sterile line and the maintainer line of the pepper with the same and stable agronomic traits are obtained through screening. Materials are easy to obtain, and the resource utilization rate is increased; the cytoplasmic-nuclear interaction type restorer line can be simultaneously transformed into a corresponding sterile line and a maintainer line, and stable inheritance can be realized; the bred sterile line is stable, the sterile plant rate reaches 100%, and a way is provided for three-line hybrid seed production. 本发明属于蔬菜作物育种技术领域，本发明提出了一种将质核互作型恢复系(基因型为
