The invention discloses a method for screening a breeding hen semen storage capability character candidate site and application, belonging to the technical field of poultry molecular marker screening and identification. The number of experimental samples is greatly reduced by a method of artificially constructing phenotype gradient difference groups, and the research cost is effectively reduced; the screening method has the advantages of abundant data volume and high detection precision. According to the invention, 5 candidate sites of the sperm storage capacity character of the hen are obtained by screening based on the method, so that the genetic improvement efficiency of the hen is effectively improved, the cost of breeding work is reduced, and a theoretical basis is provided for the actual work of breeding the hen. |
