Zusammenfassung:	The invention discloses a breeding method for rapidly improving corn stem rot resistance. The invention belongs to the technical field of molecular breeding of crops, and particularly relates to a breeding method for rapidly improving corn stem rot resistance. The genotype of an SNP site in a corn genome is detected, the SNP site is a site on a corn chromosome, the nucleotide type of the SNP site is T or C, and the SNP site is the 3412th nucleotide of a sequence 4 in a sequence table; and selecting the corn with the genotype of TT as a parent for cross breeding to obtain the corn with stem rot resistance. According to the invention, through foreground selection and whole genome genetic background selection, a relatively short segment containing an anti-disease gene is introduced into an excellent corn material, so that the excellent characters of the original inbred line are completely retained, and the stem rot resistance is remarkably improved. Corn seedlings are obtained through corn immature embryo cultur
