一种与鸡胸肌重性状相关的分子标记及其应用
By screening the chicken genome through genome-wide association analysis, the SNP locus Chr13:15953853, which is associated with chicken breast muscle weight, was identified. This solved the problem of low efficiency in traditional breeding methods, enabled early genetic assessment and efficient breeding, and promoted the rapid selection and breeding of high-quality chicken breeds.

AI Technical Summary
Traditional broiler breeding relies on phenotypic selection methods, which are inefficient and make it difficult to accurately predict genetic potential in early stages of an individual. Existing molecular marker-assisted selection technology has limitations in the study of chicken breast muscle weight traits, and there is a lack of effective molecular marker and genomic selection methods.
Genome-wide association analysis (GWAS) was used to screen for candidate genes and SNPs that are significantly associated with breast muscle weight in chickens, especially the SNP site Chr13:15953853 on chromosome 13 of the chicken genome. Chickens with the genotype GG or GA showed higher breast muscle weight, while those with the AA genotype showed lower weight. This provides a scientific basis for early genetic assessment and breeding selection.
This enables accurate prediction of chicken breast muscle weight traits at an early stage, shortens the generation interval in breeding, accelerates the breeding process of high-quality chicken breeds, and improves breeding and selection efficiency.
