The identification of markers and genes for growth traits may not only benefit for marker assist selection /genomic selection but also provide important information for understanding the genetic foundation of growth traits in broilers.
In the current study, we estimated the genetic parameters of eight growth traits in broilers and carried out the genome-wide association studies for these growth traits. A total of 113 QTNs discovered by multiple methods together, and some genes, including ACTA1, IGF2BP1, TAPT1, LDB2, PRKCA, TGFBR2, GLI3, SLC16A7, INHBA, BAMBI, APCDD1, GPR39, and GATA4, were identified as important candidate genes for rapid growth in broilers.
The results of this study will provide important information for understanding the genetic foundation of growth traits in broilers.
生长性状标记和基因的鉴定不仅有助于标记辅助选择/基因组选择，而且为理解肉鸡生长性状的遗传基础提供了重要信息。
本研究估计了肉鸡 8 个生长性状的遗传参数，并对这些生长性状进行了全基因组关联研究。通过多种方法共发现了 113 个 QTN，其中一些基因，包括 ACTA1、IGF2BP1、TAPT1、LDB2、PRKCA、TGFBR2、GLI3、SLC16A7、INHBA、BAMBI、APCDD1、GPR39 和 GATA4，被鉴定为肉鸡快速生长的重要候选基因。
本研究结果将为理解肉鸡生长性状的遗传基础提供重要信息。
