The invention provides a molecular marker for detecting a crop premature senility gene and application of the molecular marker, and belongs to the technical field of crop breeding. The molecular marker for detecting the crop premature senility gene provided by the invention can be used for detecting premature senility related genes formed by frameshift mutation due to deletion of four basic groups AACA on the eleventh exon in a coding region of the gene LOCOs03g31550. Research shows that rice containing the premature senility related gene can have a stable premature senility phenotype, leaf tip dry premature senility phenotypes of a second leaf and a third leaf appear in the 10th day after sowing in a field environment, and senility lasts to a mature period. In the tillering stage, the photosynthetic pigment content of mesophyll cells is obviously reduced, the chloroplast structure is changed, light damage is serious, photosynthesis is weakened, and the uric acid content is reduced. The ...
