The invention discloses a molecular marker closely linked with a rape pod length character and application of the molecular marker, and relates to the field of plant molecular biology. The molecular marker provided by the invention is C4-ID28, and comprises a forward primer and a reverse primer of which the nucleotide sequences are respectively shown as SEQ ID NO.1 and SEQ ID NO.2. Through identification, the primer of the molecular marker can be used for genotype identification in the early stage of breeding, and when the amplification result of the primer is a single electrophoretic band, the single plant is judged to be in a short-silique phenotype; and if the amplification result is two electrophoretic bands, determining that the single plant is in a long-silique phenotype. The primer can accurately screen the silique length phenotype, significantly improve the selection efficiency and reduce the field workload, thereby accelerating the breeding process.
