description The invention provides a molecular marker related to sheep growth traits and application of the molecular marker. The sheep FADS3 gene is subjected to PCR amplification and sequence analysis, it is found that an A/C polymorphic site exists at the 111 < th > site of an amplified fragment, a KASPar primer is further used for detecting the polymorphic sites of 1195 sheep and establishing a least square model, the genotype and growth traits are subjected to correlation analysis, and the genotype and growth traits of the sheep are subjected to PCR amplification and sequence analysis. Finally, it is determined that the amplified FADS3 gene segment can be used as the molecular marker related to the sheep growth traits. By detecting the molecular marker, the homozygous sheep with the gene AA is selected to enter a core group to serve as breeding sheep, so that the growth traits of the sheep are improved, the breeding process can be shortened, and the economic benefits of the breeding industry can be improved. 本发明提供了一
