摘要
为改良连城白鸭的生长性能,研究选用连城白鸭为母本素材,与丽佳鸭杂交选育连城白鸭肉用新品系。对新品系各世代雏鸭喙、脚和羽色综合性状进行分级和评分,分析综合性状世代选育进展和选择效果。结果表明,经4个世代的选育,雏鸭乌喙、青脚和白羽综合性状的比率由0%提高到98.13%;评分平均值由3.2106提高到9.7248,平均实现遗传力为0.5826,选育进展极其显著。同时,研究表明该项选育技术路线正确、有效和实用。
In order to improve growth performance,Liancheng white duck and Lijia duck were used as female and male parents to select a new meat strain of Lianeheng white duck. The properties of beak,shank and plumage color of duck were graded and scored in each generation,and the generation development and breeding effect on consolidated properties were analyzed. The result showed that through four generations selection ,the rate of black beak ,black shank and white plumage was improved from 0% to 98.13%,and the average score was improved from 3.2106 to 9.7248. The average realized heritability of five generations was 0.5826. The breeding progress was significant. At the same time,the result showed that this route of breeding technology was correct and available.
