SNP (Single Nucleotide Polymorphism) molecular module related to eggshell weight and application thereof

The invention relates to the technical field of laying hen breeding, in particular to an SNP (Single Nucleotide Polymorphism) molecular module related to egg shell weight and application thereof. According to the SNP molecular module provided by the invention, the problem that the production potential cannot be fully exerted when a single molecular marker is used for breeding is avoided, laying hens with higher egg shell weight can be more accurately bred, and the egg shell weight regulation and control effect on the whole breeding period of the laying hens is obvious; the method can help to save production cost and accelerate genetic progress, has great economic application value and scientific research value, and is an optimization and upgrade of a molecular marking technology. 本发明涉及蛋鸡育种技术领域，特别是涉及一种与鸡蛋蛋壳重相关的SNP分子模块及其应用。本发明提供的SNP分子模块避免了以单一分子标记育种不能充分发挥其生产潜能的问题，可以更加精准地选育蛋壳重量更高的蛋鸡，对蛋鸡饲养全周期的蛋壳重调控效果明显；能够有助于节省生产成本并加快遗传进展，具有很大的经济应用价值和科研价值，是对分子标记技术的优化升级。
