Marker associated with powdery mildew resistance in plant of genus Fragaria and use thereof

This invention intends to develop many DNA markers for a plant of the genus Fragaria and detect powdery mildew resistance with high precision by using the many DNA markers. The marker associated with powdery mildew resistance in a plant of the genus Fragaria comprises a continuous nucleic acid region sandwiched between the nucleotide sequence as shown in SEQ ID NO: 1 and the nucleotide sequence as shown in SEQ ID NO: 19 in the chromosome of the plant of the genus Fragaria.本发明旨在针对草莓属（Fragaria）植物开发多个DNA标记（DNA marker），并通过这些DNA标记实现高精度的白粉病抗性检测。与草莓属植物白粉病抗性相关的DNA标记，是指该类植物染色体中，由SEQ ID NO:1所示核苷酸序列与SEQ ID NO:19所示核苷酸序列夹合的连续核酸区域。
