Abstract:

The aim of this study was to use genome-wide association analysis to explore the candidate genes and molecular markers associated with various economic traits. The GWAS of the body weight at d1,d28,d56,d80,d100 of Beijing-You chicken using the Illumina 60K SNP Beadchip was performed. The results showed that there were 9 SNPs reaching 5% Bonferroni genome-wide significance, which were significantly associated with body weight at d28 and d100, including LYRM1, LDB2 and other genes near these SNPs; There were 96 SNPs reaching the significance of “suggestive linkage”, which were potentially associated with each indexes detected. The result revealed that these genes and SNPs laid a foundation for the development of techniques of marker assisted selection.
