| 摘 要： | 1992年根据武定鸡农大Ⅰ系26个父系家系6批出壳雏鸡2013只主翼羽和覆主翼羽的生长特点,将该鸡种初生雏鸡羽型分为:快羽-型、慢羽四型.表型慢羽个体占13.26%,快羽个体占86.74%,K(慢)、k(快)基因频率分别为0.0698和0.9302,经基因型测交和纯繁扩群.基本育成武定鸡快、慢羽两个纯系.用两系配套繁殖或用该鸡种的慢羽母鸡同红布罗快羽公鸡杂交,其雏鸡羽速自别雌雄的准确率平均为98.57%.

| Abstract: | 2013chicks were selectively hatched from 26 male parent lines of Wuding-Agr UI chicken in 1992.We classified them into fast-feathering(Ⅰ) and slow-feathering(Ⅳ) types on basis of growing characters of their pninaries and primary-coverts.Phenotypic ratio of slow-feathering type 86.74%,The gene freguency of k(fast) and k(slow) was 0.0698 and 0.9302 respectively.Fast-feathering and slow-feathering pure Lines of Wuding chicken have been successfully bred through gene resting cross and Pure-Line breeding.There fore chicks for auto-sexing of fast-feathering male with slow-feathering female of Wuding Agr·U·I and between fast-feathering redbro malewith pure line of slow-feathering female of Wuding-Agr·U·I The accurate rate of feathering for auto-sexing is 98～57%. |
