The invention provides a molecular marker closely linked with a major QTL (Quantitative Trait Loci) of a pod length character of brassica napus and application of the molecular marker, and belongs to the technical field of molecular biology and rape breeding. The molecular marker disclosed by the invention is an InDel molecular marker, and is named as SLA02-9 and SLA02-14; wherein the nucleotide sequence of the SLA02-9 is as shown in SEQ ID NO. 5, and the nucleotide sequence of the SLA02-14 is as shown in SEQ ID NO. 6. The excellent molecular marker is provided for brassica napus pod length breeding improvement, a pod growth material is selected and bred through molecular marker-assisted selection, then high-yield rape can be cultivated, the method has the advantages of being good in accuracy, high in efficiency and high in cost performance, and cloning of rape pod length related genes and development of pod length related gene functional markers are facilitated. 本发明提供了一种与甘蓝型油菜角果长性状的主效QTL位点紧密连锁的分子标记及应用，属于分子生物
