摘　　要：采用北京油鸡(YY)与矮脚黄鸡(DD)、石歧黄鸡(CC)分别进行正反杂交,观测亲本及其杂交组合的生长性能、胴体性状、肌苷酸(IMP)和肌内脂肪(IMF)等肉品风味性状,比较各性状的杂种优势,为培育优质北京油鸡配套系提供理论依据。结果表明,YY与DD杂交组合(YD)的增重、料肉比及产肉量杂种优势明显,胸肉IMP和IMF含量未降低。因此YD组合既能保持商品代鸡肉较高的IMP和IMF含量,同时能节省父母代养殖成本,并有效防止种源的流失。Beijing Fatty （YY）chicken,Aijiao Huang （DD）chicken,Shiqi Huang （CC）chicken and their crossbred chickens were used for study.The growth performance,carcass traits,inosinic 5＇-monophosphate（IMP） and intramuscular fat（IMF）contents were tested. The heterosis of different combinations were compared. The results showed that when YY was crossed with DD,there were significant higher heterosis on growth rate,feed conversion ratio and meat yield,and the IMP and IMF contents of meat was not decreased.
