The invention relates to the technical field of molecular markers, in particular to an SNP (Single Nucleotide Polymorphism) marker combination related to the hardness of sweet corn kernels and peels and application of the SNP marker combination. Sweet corn selfing lines SHL01 and SHL03 are used as parents to construct an RIL group (permanent group), a texture analyzer is used for collecting related property data of the peel hardness of the sweet corn kernels, QTL positioning is carried out through the peel hardness property of the kernels, it is found that a major QTL related to the peel hardness of the sweet corn kernels exists on the sixth chromosome of the corn, the major QTL is located between SNP loci SChr6: 16190361 and SChr6: 162070558, and the major QTL is located between the SNP loci SChr6: 16190361 and SChr6: 162070558. The contribution rate to the grain peel hardness phenotype is 13.49%, and the obtained major QTL-linked SNP marker (namely the SNP marker combination) lays a foundation for molecular
