Slaughter traits are crucial economic traits of chickens. We performed a GWAS to discover critical loci and candidate genes for 21 slaughter traits in an F2 chicken population resulting from crossing Luxi gamecocks and recessive white feather broilers. We found some SNPs and genes which were significantly associated with keel length, head length, body slope length, bilateral leg weight without shin, bilateral foot weight, subcutaneous fat thickness, heart weight, muscular stomach weight and glandular stomach weight. This study provides references for further investigation of slaughter traits and molecular breeding in chicken.

使用全基因组关联研究鉴定与 F2 鸡群屠宰性状相关的候选基因

屠宰性状是鸡的重要经济性状。我们进行了 GWAS 以发现 F2 鸡群中 21 个屠宰性状的关键基因座和候选基因,该种群是由鲁西斗鸡和隐性白羽肉鸡杂交产生的。我们发现了一些与龙骨长度、头部长度、身体坡度长度、双侧无胫骨重量、双侧足部重量、皮下脂肪厚度、心脏重量、肌肉胃重量和腺胃重量显着相关的 SNP 和基因。本研究为进一步研究鸡的屠宰性状和分子育种提供参考。
