SSR (simple sequence repeat) markers, linked with Aphelenchoides besseyi Christie resistant QTL (quantitative trait locus), on chromosome 9 and application thereof

The invention discloses molecular markers linked with an Aphelenchoides besseyi Christie resistant QTL (quantitative trait locus). The essence of the molecular markers is that according to the linkage and segregation rules, the population of the hybrid generation F2 of the Aphelenchoides besseyi Christie resistant variety Tetep and the susceptible variety Huaidao 5 is taken as the mapping population, and the SSR (simple sequence repeat) markers RM5526 and RM3912, linked with the Aphelenchoides besseyi Christie resistant QTL, on the chromosome 9 are obtained through analysis of linkage between the identification results of Aphelenchoides besseyi Christie resistance and the SSR marker data. Whether a plant has Aphelenchoides besseyi Christie resistance can be judged by detecting the SSR marker banding pattern of the single rice plant of the hybrid combination generation of Tetep and derived varieties (lines) thereof and the Aphelenchoides besseyi Christie susceptible variety. After being applied to assistant se
