| 摘要: |
| 对我国部分地方鸡种泰和鸡、仙居鸡、固始鸡、萧山鸡、油鸡、狼山鸡（N系）等进行了羽性伴性遗传观察。结果表明，泰和鸡、仙居鸡为快羽型，固始鸡、萧山鸡、油鸡为慢羽型，狼山鸡（N系）为快慢羽型。这些鸡种按快慢羽伴性遗传配套杂交，F1代均能自别雌雄。 |

| Abstract: |
| An observation on the feather growth rate linked with sex is conducted in several local breeds of chicken.These breeds include Taihe Silky Fowl,Xianju Fowl,Gushi Fowl,Xiaoshan Fowl,Youji Fowl and Langshan Fowl (N strain).The result is as follows:Taihe Silky Fowl and Xianju Fowl carry fast growth type of feather,Gushi Fowl,Xiaoshan Fowl and Youji Fowl carry slow growth type of feather,and Langshan Fowl (N strain) has both types.It is suggested that these breeds might be applied to feather sexing in crossing. |
