The results showed that in this commercial pig population,the frequency of allele A was 0.6371,B was 0.3629;the genotype frequency of AA was 0.4516,AB was 0.3710,BB was 0.1774,and the χ2 test showed that the allele frequencies were in Hardy-Weinberg equilibrium. The SPSS GLM procedure was used to identify the association of the 313 bp indel with reproductive traits. In Sutai pigs,the pigs with AA genotype represented higher value in all reproduction traits,except for higher survival rate of piglets at weaning. Higher weaning weight was signifi cantly associated with AA genotype pigs and higher survival rate of piglets at weaning was signifi cantly associated with BB genotype(P<0.05) ,but no signif icant differences in other reproduction traits among genotypes were found(P>0.05) ;the P value of different traits affected by fi xed factors were not signif icant as well(P>0.05) . The result indicated that although this 313 bp indel was signifi cantly associated with the weaning weight and survival rate at weaning,no any association with major reproduction traits was observed in Sutai pigs. 关 键 词：繁殖性状 POU1F1基因 商品猪 BP 协会 多态性 基因型频率 等位基因频率
