The invention discloses a precise introduction and identification method for excellent characters of corn, and belongs to the field of crop breeding. The technical problem to be solved by the invention is how to realize accurate introduction of excellent characters of corn. The invention provides a corn target character introduction method which comprises the following steps: S1) hybridizing corn with target characters with a receptor inbred line to obtain F1; s2) taking the haploid induction line as a male parent and the F1 in the step S1) as a female parent for hybridization, and screening haploids with target characters; s3) taking the receptor inbred line in the step S1) as a male parent and the haploid in the step S2) as a female parent, and hybridizing to obtain an HBC1 group; s4) planting the HBC1 group in rows, taking the HBC1 group single plant as a female parent, taking the receptor inbred line as a male parent, performing backcross, and continuously performing N generations to obtain a strain with
