The invention provides an SNP molecular marker related to rice bacterial leaf blight resistance, a detection primer pair and application, and relates to the technical field of crop genetic breeding. The SNP molecular marker is obtained through a whole genome correlation analysis method, the SNP molecular marker is located on nucleotide single base mutation at the 27792921bp position of the 11chromosome of a rice reference genome and nucleotide single base mutation at the 26220673bp position of the 11 chromosome, genes located nearby the SNP molecular marker are genes encoding NBS-LRRdisease-resistant protein domains, and the genes are related to rice disease resistance. By means of the SNP molecular marker, resistance genes remarkably related to bacterial leaf blight resistance can be found, a detection method for expression in a resistance material is established, and gene resources are provided for subsequent rice disease-resistant breeding. 本发明提供了一种与水稻白叶枯病抗性相关的SNP分子标记、检测引物对及应用，涉及作物遗传育种技术领域。本发明所述SNP分子标记是通过全
