| 摘 要： | 采用混合家系方差组分剖分法对白羽番鸭RF系的主要经济性状遗传参数进行了估计。结果初生重、 42日龄体重、 0～ 70日龄体重、 70日龄日增重、开产体重、 0～ 70日龄料重比、开产日龄、 30 0日龄产蛋量、 30 0日龄蛋重和 50 0日龄产蛋量的遗传力分别为 0 54、 0 48、 0 56、 0 37、0 2 9、 0 34、 0 55、 0 2 5、 0 55和 0 2 1。同时 ,对各性状的遗传相关和表型相关进行了估计和分析。

| Abstract: | The genetic parameters of major quantity traits of white feather muscovy duck RF line were estimated with variance component of the mixed family. The results are as follows: The heritability of birth body weight, body weight at 42 days, body weight at 70 days, average daily gain from birth to 70 days, feed efficiency to 70 days of age, first laying age, egg number to 300 days, egg weight at 300 days and egg number to 500 days were 0 54,0 48,0 56,0 37,0 29,0 34,0 55,0 25 and 0 55. The genetic and phenotypic correlation coefficiencies were estimated. |
