SNP (Single Nucleotide Polymorphism) molecular marker closely linked with grape fruit cracking gene as well as obtaining method and application of SNP molecular marker

The invention belongs to the technical field of biotechnology engineering and grape breeding, and particularly discloses an SNP molecular marker closely linked with a grape fruit cracking gene and an obtaining method and application of the SNP molecular marker. SNP loci are obtained on the basis of whole genome sequencing through correlation analysis and experimental verification; the SNP molecular marker combination is composed of two SNP marker loci, and the SNP molecular marker combination can be used for molecular marker assisted breeding of the grape fruit cracking character, individuals can be directly bred on the genome level in the early stage without depending on phenotypic information, the selection efficiency of the grape fruit cracking character can be remarkably improved, the breeding process is accelerated, and the cultivation and management cost of intermediate hybrid seedlings is saved; the breeding efficiency is improved, the breeding cost is reduced, and the method has a wide application pro
