The invention discloses an SSR (Simple Sequence Repeat) molecular marker closely linked with the plant height character of brassica napus and application of the SSR molecular marker. According to the method, brassica napus C76 is used as a female parent, a mutant bgr-JT of brassica campestris is used as a male parent, and intra-genus interspecific hybridization is performed to obtain F1-generation seeds; the offspring which is compact in plant type and shorter in plant height is selected from the F1 to be backcrossed with the brassica napus C76, and the offspring which is compact in plant type and shorter in plant height is selected from the F1BC1 to be backcrossed with the brassica napus C76. According to the method, flower buds generated by strains with compact plant types and shortened plant heights in descendants of F1BC2 are selected, microspore culture is carried out, and a brassica napus DH line material Bnbgr with the compact plant types and the dwarf brassica napus DH line material Bnbgr is obtained
