The invention relates to a breeding technique, and particularly provides a polymerization selection method of a superior line in a same corn group. The method comprises the steps of selecting two pure lines with excellent and complementary comprehensive agronomic characters from the same corn class group, performing hybridization, performing self-cross breeding or haploid induction doubling on a hybridized generation, and finally breeding a new pure line with a comprehensive agronomic character superior to those of parents of the new pure line. According to the polymerization selection method of the superior line in the same corn group, basic selection materials belong to the same class group, the comprehensive agronomic characters are complementary, and the comprehensive agronomic character of the bred new pure line is superior to those of two same group parents of the new pure line. The method accelerates enrichment of early-mature, dense-resistant and mechanical-reaped germplasm resources and breeding work
