摘　　要：采用PCR-RFLP方法,对3个外种猪群FUT1基因多态性进行了检测。结果表明,杜洛克猪群中检测到AA、AG和GG 3种基因型,长白和大白猪群中仅检测到GG和AG 2种基因型,未检测到EFC18抗性AA基因型。卡方检验结果表明,3个外种猪群该位点均处于Hardy-Weinberg遗传平衡(P>0.05)。群体中该位点纯合度较高,杂合度较低,除杜洛克猪群具有中度遗传多态性外,其余2个猪群该位点遗传多态性较低。可在后续的育种方案中实施基因型选配,扩大群体中EFC18抗性AA基因型个体数量。Polymorphisms of FUT1 gene was detected by using PCR-RFLP method in three foreign pig herds.Only genotype AG and GG but no anti-EFC18 genotype AA was found in Landrace and Yorkshire except Duroc herd.The χ2 analysis result showed that FUT1 gene of these three pig herds was in Hardy-Weinberg equilibrium(P>0.05).There was high homozygosity but low heterozygosity of FUT1 gene in these populations.Low genetic polymorphism was found in Landrace and Yorkshire herds but medium genetic polymorphism in Duroc herds.Genotypic selection can be carried out to amplify number of pigs with anti-EFC18 genotype AA.
