The invention relates to a method for breeding sorghum restorer Ji R5062 through sister hybridization. The method comprises the following steps of: 1, determining a breeding target, and selecting a sorghum restorer type parent; 2, performing artificial emasculation hybridization to obtain the first generation of hybrid; 3, planting the first generation of hybrid, and mixing and harvesting; 4, planting F2, and selecting the single plant with excellent characters from the segregation population; 5, selecting sister lines with complementary characters and performing artificial emasculation hybridization; 6, planting the first generation of sister hybridization, and mixing and harvesting; 7, planting F2, and selecting the single plant with excellent target characters; and 8, performing selfing and test cross.
