The invention discloses a method for identifying tomato variety DNA fingerprints and an SNP primer combination used in the method. The method comprises the following steps: genotypes of a to-be-detected tomato and 441 tomato varieties based on 40 SNP loci are detected respectively, and then the following judgment is carried out: if the genotype of the to-be-detected tomato based on the 40 SNP loci is completely consistent with that of one variety in the 441 tomato varieties, the to-be-detected tomato and the tomato variety belong to the same variety. The method provided by the invention can be used for early identification of the tomato varieties in a seed or seedling stage, ensures the authenticity of the varieties, practically protects the rights and interests of producers and breeders, and provides technical support for protecting tomato germplasm resources and new varieties. The method provided by the invention not only can be used for identifying unknown tomato varieties, but also can be used for identifying the authenticity of known varieties. The method provided by the invention has the advantages of being high in flux, accurate, low in cost and simple to operate, saving manpower and material resources and the like, and has a very wide application prospect.
