摘　　要：试验选用广西三黄鸡为母本、贵妃鸡为父本,按照试验设计和规定指标,进行杂交,选育杂交后代,再以回交的方法来固定目标性状,并对杂交F3代进行产蛋性能及蛋品质等有关指标的研究。结果表明,杂交F3代产蛋期存活率高,耗料少,种蛋合格率水平高,具有良好的产蛋性能,其蛋重、蛋壳强度、蛋壳厚度、蛋黄颜色、蛋的相对密度、蛋形指数、蛋黄指数、蛋壳比率、蛋黄比率、蛋白比率、哈氏单位的测定结果平均值分别为38.92 g、3.98 kg/cm2、313.67μm、7.19、1.06、1.39、0.44、0.11、0.35、0.54、78.65。Based on the experimental design and stipulated index, cross experiment was carried out by using royal chickens as male parent and Guangxi-sanhuang chickens as female parent. After the breeding of hybrid offsprings, the target traits were fixed by the backcross method. The laying performance and egg quality of hybrid F3 were evaluated. The results showed that the hybrid F3 had a high survival rate in laying period and less feed consumption. The qualified rate of hatching egg of the hybrid 173 was higher. The hybrid F3 had an excellent laying performance, their egg weight （EW）, shell strength （SS）, shell thickness （ST）, yolk color （YC）, the relative density of eggs （RDE）, egg shape index （SI）, yolk index （YI）, eggshell proportion （EP）, yolk proportion （YP）, protein proportion （PP）, Haugh unit （HU） were 38.92 g, 3.98 kg/cm2, 313.67 μm, 7.19, 1.06, 1.39, 0.44, 0.11, 0.35, 0.54 and 78.65, respectively.
