摘要: 为探索OLR1基因遗传多态性对硒都黑猪产仔数的影响,利用直接测序法检测OLR1基因在硒都黑猪中的遗传多态性,并与产仔性状进行了关联分析。结果表明,在第四内含子7 bp处发现一个T/C突变,存在3种基因型TT、TC和CC;TT基因型个体的总产仔数和产活仔数都极显著高于TC和CC基因型个体(P<0.01),说明该突变对硒都黑猪产仔数性状有极显著的影响。

关键词: OLR1基因, 硒都黑猪, 产仔数, 关联分析

Abstract: In order to explore the effect of OLR1 gene genetic polymorphism on litter size of Xidu black pigs, the direct sequencing method was used to detect the genetic polymorphism of OLR1 gene in the Xidu black pigs, and the association analysis with litter size was carried out. The results showed that there was a T/C mutation at 7 bp of intron 4, and there were three genotypes TT, TC and CC; The total number born and number born alive of individuals with TT genotype were extremely significantly higher than those with TC and CC genotype (P<0.01), indicating that the mutation had a significant impact on litter size traits of Xidu black pig.

Key words: OLR1 gene, Xidu black pig, litter size, association analysis
