摘要
以北京鸭配套系中的父系为研究对象,通过分析胸肌质量的分化生长率、拟合胸肌发育的数学模型以及比较胸肌直接和间接选择效果等方法系统研究了北京鸭胸肌的生长发育规律,结果表明胸肌是晚熟性状,与其他模型相比,Logistic模型更适合描述北京鸭胸肌生长发育规律,而龙骨长度较适合作为胸肌质量的间接选择指标.
In this research, the growth rules of pectoral of Peking duck coming from the paternal line were analyzed and the mathematical models for the growing pectoral were also estimated. In addition, direct and indirect selection responses on pectorals were further compared. Results indicated that pectoral was late-maturing and logistic function was fit for describing the growth rule of the pectoral mass. The length of breastbone could be used as a marker in pectoral selection.
