Keyword:  湛江三黄鸡FASN基因A-FABP基因腹脂率;
Abstract: 以102只湛江三黄鸡为材料,采用PCR-RFLP方法,分析FA SN基因和A-FA BP基因的多态性对其中30只个体进行屠宰测定以分析基因型与屠宰性状间的相关性.研究结果表明,HaeⅢ酶切扩增的FASN基因,检测出多态,B等位基因频率0.7828,明显高于C等位基因,基因频率分布态势与红色原鸡相同,而与多个培育鸡品种不同.HinfⅠ酶切A-FA BP基因,检测到突变,A等位基因频率0.9559,占绝对优势.基因型与屠宰和腹脂性状的相关分析表明,FASN基因位点为CC基因型鸡的腹脂率最低,而屠宰率以BB基因型鸡较高.
