青壳蛋鸡肤色遗传观测

 试验以测交纯合青壳蛋鸡公鸡（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。试验结果表明:青壳蛋鸡公鸡肤色基因型为“PPZ^idZ^id”, 海兰白母鸡肤色基因型为“ppZ^idW^- ”,泰和鸡肤色基因型为“PPZ^idW^- ”,狼山鸡母鸡肤色基因型为“ppZ^idW^- ”;以青壳蛋鸡公鸡为父本,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。以青壳蛋鸡公鸡为父本,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。

Observation Inheritance on Skin Colour of Green-shell-egg Fowl

The test observe inheritance of skin colour,using testcross purebred Green shell egg Fowl rooster(skin and shank color is black) as paternal chicken,using Hailan White Fowl(skin color is yellow),Langsa Fowl, Taihe Silky Fowl (shank color is black)as maternal specimen. The result indicate that:Green shell egg Fowl roosters' skin colour genotypic is "PPZ id Z id ";Hailan White Fowl hens' skin colour genotypic is"ppZ id W -"; Langshan Fowl hens,skin colour genotypic is "ppZ id W -"Taihe Silky Fowl hens' skin colour genotypic is "PPZ id W -".Green shell egg Fowl cock crossing with Hailan White Fowl hen,F 1 generation chicken skin colour can be exerted to distinguish hens or roosters,all cocks,skin colour is yellow and all hens' skin colour is black.Green shell egg Fowl rooster crossing with Taihe Silky Fowl hen or Langshan Fowl hen,soever cocks' or hens' of F 1 generation Skin colour is black.
