摘要/Abstract

摘要：

肉鸡胴体外观与肉质性状的遗传改良是当前肉鸡产业提质增效的关键研究方向。随着冰鲜鸡市场的快速发展和消费者对品质需求的提升，胴体外观(如皮肤色、毛孔密度、体尺)与肉质(如肉色、嫩度、肌内脂肪)成为影响市场竞争力的核心指标。本文系统综述了全基因组关联分析(GWAS)技术在家禽遗传育种中的应用进展，重点总结了近年来通过GWAS等组学技术筛选出的胴体外观与肉质性状相关候选基因，如影响体尺的LCORL、LDB2，调控皮肤色的BCO2、TYR，关联毛孔密度的Wnt3A，以及参与肉色形成的ATP5L、COL1A2等。此外，本文还讨论了肌内脂肪沉积基因(如FASN、PLA2G4F)和嫩度相关基因(如CAPN1、CAST)的功能及其育种价值。通过整合现有研究成果，本文旨在为肉鸡分子标记辅助育种提供理论依据，并为未来功能基因组学与精准育种研究指明方向。

Abstract:

Genetic improvement of carcass appearance and meat quality traits in broilers is pivotal for enhancing production efficiency and meeting market demands. With the rapid expansion of chilled chicken markets and increasing consumer emphasis on product quality, traits such as carcass appearance (eg., skin color, pore density, body size) and meat quality (e.g., meat color, tenderness, intramuscular fat) have become critical determinants of commercial competitiveness. This review systematically summarizes the application of genome-wide association studies (GWAS) in poultry breeding, highlighting the candidate genes identified through GWAS, transcriptomics, and multi-omics approaches. Key genes include LCORL and LDB2 (affecting body size), BCO2 and TYR (affecting skin pigmentation), Wnt3A (affecting pore development), ATP5L and COL1A2 (affecting meat color), FASN and PLA2G4F (affecting intramuscular fat deposition), as well as CAPN1 and CAST (affecting tenderness). By synthesizing current findings, this paper provides a theoretical foundation for marker-assisted breeding and proposes future research directions in functional genomics and precision breeding.
