The invention relates to a molecular marker tightly linked with a major QTL (Quantitative Trait Loci) of the cotton seed oil content of upland cotton and application thereof. The molecular marker tightly linked with the major QTL of the cotton seed oil content of upland cotton is TMB1216. The molecular marker TMB1216 can be applied to the genotype detection of an upland cotton variety or strain to judge the oil content of the variety or strain. In the invention, the molecular marker TMB1216 is used for assisting in selecting, so that high accuracy is achieved, the selecting speed is increased, the breeding workload is lowered greatly simultaneously, the breeding efficiency is increased, and the defects and disadvantages of long period, high subsequent screening workload, low verification efficiency of the variety or strain and the like existing in the conventional breeding are overcome.
