摘  要：
以丽佳鸭为父本、连城白鸭为母本,应用杂交、多代横交技术和群体继代选育方法,逐步固定白羽、乌喙和青脚性状,选育出2个连城白鸭肉用新品系(Ⅰ和Ⅱ)。2个新品系分别经过4个世代和3个世代选育,白羽、乌喙和青脚综合性状的比率均从0%分别提高到99.01%和99.35%,平均实现遗传力达到0.808 9和0.951 7。连城白鸭新品系Ⅰ系肉鸭7周龄公母平均体重达1 824.64±170.90g,平均饲料转化率2.93∶1;Ⅱ系肉鸭7周龄公母平均体重2 168.22±219g,平均饲料转化率2.78∶1,比基础群连城白鸭生长速度分别提高了95.0%和131.6%、饲料转化率分别提高了12.3%和16.8%。结果表明选育效果极其显著。

摘  要：
Two new meat strains of Liancheng white duck(I and II) were selected from Lijia duck and Liancheng white duck as parents by the methods of the technology of hybridization and a multi-generation transversely breed,and colony continuing selection,and the traits of white feather,beak and green feet were fixed gradually.After 3 and 4 generations dreeding,the compositive trait rate of white feather,black beak and green feet in the two new meat strains was improved from 0% to 99.01% and 99.35%,and mean heritability of 0.808 9 and 0.951 7 was achieved,respectively.At the age of 7 weeks,the average bodyweight and the average feed conversion efficiency of the male and female ducks in strainⅠand strain II was 1824.64±170.90 g and 2.93∶1,2168.22±219 g and 2.78∶1,respectively.Compared with the basic population-Liancheng white duck,the growth rate of the two new strains was increased by 95.0% and 131.6% and the feed conversion efficiency by 12.3% and 16.8%,respectively.The results showed that the selection effects were extremely significant.
