金湖乌骨鸡肤色遗传观测

Observation on Inheritance of Skin Color of Jinhu Chicken

[目的]探明金湖乌骨鸡肤色遗传规律。[方法]以金湖乌骨鸡公鸡(黑胫、黑皮肤)为父本,以海兰白(黄色胫)、泰和鸡、狼山鸡母鸡(黑色胫)为母本,对肤色进行遗传观测。[结果]金湖乌骨鸡公鸡肤色基因型为PPZidZid,海兰白母鸡肤色基因型为ppZIdW-,泰和鸡肤色基因型为PPZidW-,狼山鸡母鸡肤色基因型为pp ZidW-,以金湖乌骨鸡公鸡为父本,海兰白母鸡为母本进行杂交,F1代肤色能自别雌雄,公鸡为黄皮肤,母鸡为黑皮肤。以金湖乌骨鸡公鸡为父本,泰和鸡、狼山鸡母鸡为母本,F1代肤色无论公鸡、母鸡都是黑色。[结论]探明金湖乌骨鸡肤色遗传规律,为今后的育种提供了理论依据。

[ Objective] The research aimed to survey inheritance of skin color of Jinhu Chicken. [Method] The inheritance of skin color was observed, using Jinhu Chicken rooster （skin and shank color is black） as paternal chicken,nsing Hailan White Fowl （skin color is yellow）, Langsa Fowl, Taihe Silky Fowl （shank color is black） as maternal specimen. [Result] Skin color genotype of Jinhu Chicken roosters was PPZidZid. Skin color genotype of Hailan White Fowl hens was PPZ^idW^- .Skin color genotype of Langshan Fowl hens was PPZ^idW^- .Skin color genotype of Taihe Silky Fowl hens was PPZ^idW^-,.Jinhu Chicken cock crossed with Hailan White Fowl hen. Skin color of F1 generation chickou could be exerted to distinguish hens or roosters. Skin color of all cocks was yellow and that of all hens was black. Jinhu Chicken rooster crossed with Taihe Silky Fowl hen or ＇I.angshan Fowl hen. Skin color of F1 generation was black. [Conclusion] The research proved up the inheritance of skin color of Jinhu Chicken, providing theoretical basis for breeding in the future.
