SNP (Single Nucleotide Polymorphism) marker for identifying purity of Qingzao 510 maize hybrid and application of SNP marker

The invention relates to the technical field of molecular biology of crops, in particular to an SNP (Single Nucleotide Polymorphism) marker for identifying the purity of a Qingzao 510 maize hybrid and application. The SNP marker for identifying the purity of the Qingzao 510 corn hybrid is selected from the following (a) and/or (b): (a) is located at the 132582645th site on the No.8 chromosome, and the deoxynucleotide of the SNP marker is T or C; (b) is located at the 60975963rd site of the chromosome 4, and the deoxynucleotide of the (b) is G or A. The SNP marker provided by the invention can identify the purity of the Qingzao 510 corn seeds at high throughput, and has the advantages of stable detection result, accuracy, rapidness and high efficiency. 本发明涉及农作物分子生物学技术领域，尤其涉及一种用于青早510玉米杂交种纯度鉴定的SNP标记及应用。本发明所述用于青早510玉米杂交种纯度鉴定的SNP标记选自以下(a)和/或(b)：(a)位于8号染色体上第132582645位，其脱氧核苷酸为T或C；(b)位于4号染色体上第60975963位，其脱氧核苷酸为G或A。本发明提供的SNP标记可高通量鉴定青早510玉米种子纯度，具有检测结果稳定、准确、快速、高效的优点。
