矮脚黄鸡与国内地方品种鸡配套生产的应用研究

Research on Application of Match-production between Yellow Dwarf Chickens and Domestic Local Chicken Breeds

选用浙江省宁波市振宁牧业有限公司育种中心携带有dw基因的纯系矮脚黄鸡K系公鸡为父本,以浙江省宁海县梅林镇当地鸡群选育而成的D系黄羽正常脚母鸡作为母本,先进行两系杂交,后分别用国内4个地方的不同品种L系、G系、H系、X系为第二父本,同KD母鸡进行三系配套杂交。通过对商品代的质量性状和数量性状的观察和测定,筛选出符合当地的配套模式。

Pure yellow dwarf chicken K-line cock which took with dw gene and was bred by breeding center of Ningbo Zhenning Husbandry Limited Company was taken as male parent, and D-line yellow-feather normal-foot hen bred from local chick in Meilin Town of Ninghai County, Zhejiang Province was taken as female parent, and two-line hybrid was carried out firstly. Then, different varieties like L-line, G-line, H-line and X-line from four regions in China were taken as the second male parent, and three-line-crossed matched hybrid was carried out with KD hen. Matching mode for local areas was screened out through observing and determining qualitative characters and quantitative characters of commercial stock.
