摘　　要：鸡的羽毛颜色作为一项重要的外观性状,既是鸡的品种特征,也是人们选择饲养鸡种类型的标准之一。同时,鸡的羽色也是表型遗传研究的重要组成部分。研究鸡羽色的遗传机制有助于培育特定羽色的鸡,从而满足不同地区的市场需求,还有助于不同品种间的区分和鸡进化的研究。文章就黑色素的种类、相关通路以及转运机制进行了概括,并就不同羽色基因突变所对应的表型进行了综述,以期为鸡羽色性状的分子选育提供参考。The feather color of chickens,as a crucial external properties,is both a breed characteristic and one of the stan⁃dards for people to choose the type of chicken breed to raise.At the same time,chicken feather color is also a vital part of pheno⁃typic genetic studies.The study of the genetic mechanism of chicken plumage color helps to breed chickens with specific plumage color to meet the market demand in different regions,and also helps to differentiate between different breeds and to study the evo⁃lution of chickens.In this paper,we provide an overview of the types of melanin,related pathways and transport mechanisms,and review the phenotypes corresponding to mutations in different feather color genes,to provide a reference for the molecular selec⁃tion of chicken feather color traits.
