摘要
通过整理湖北白猪优质系各世代的系谱资料,系统分析了湖北白猪优质系培育过程中各品种所占的血液比例,以及近交程度和世代组成的遗传结构。结果表明,选育到六世代,长白猪、湖北白猪、梅山猪和通城猪在湖北白猪优质系中的血液含量分别为45.15%、24.38%、23.39%和7.08%。湖北白猪优质系的平均近交系数为2.52%,仍处于较低水平,近交系数年增量为0.509 9%,群体有效含量为98.06头。
The blood percentage of each breed acted in the breeding of Hubei white swine line with high quality was studied through collecting and analyzing of the pedigree data of the individuals in each generation. The pedigree structures and inbred levels in each generation of Hubei white swine line with high quality were analyzed. The results showed that the percentage of Landrace, Hubei whie swine, Meishan swine and Tongcheng swine in Hubei white swine line with high quality were 45.15%, 24.38%, 23.39% and 7.08%, respectively. The average inbred coefficient was 2.52% which was in low level. The average increment was 0.509 9% per year. The available population content was 98.06.
