摘　　要：本研究采用PCR-RFLP方法对苏太猪的ESR基因PvuⅡ位点多态性进行检测,并分析其与繁殖性能间的关系。结果表明,ESR基因的3种基因型AA、AB、BB在苏太猪中的频率分别为0.089、0.570、0.341;其中在初产母猪中,AA基因型个体的产活仔数(NBA)和初生窝重(BLW)显著高于AB、BB基因型的个体(P<0.05);在经产母猪中,AA基因型个体的总产仔数(TNB)及断奶成活数(NW)显著高于AB和BB基因型的个体(P<0.05),AA和AB基因型与BB基因型之间的断奶窝重(WWL)差异显著(P<0.05);总体上苏太猪ESR基因PvuⅡ3种基因型个体的繁殖性状存在AA>AB>BB的趋势。Polymorphisms of ESR gene in Sutai pigs were were investigated by PCR-RFLP method.The relationship between ESR gene and reproduction traits were analyzed in this study.The results showed that there were genotypes AA,AB and BB in Sutai pigs,the frequencies of the ESR genotypes were 0.089,0.570 and 0.341,respectively.The correlation between three genotypes and the performances showed that the number born alive（NBA）and birth litter weight（BLW） of individuals with AA genotype were higher than those of individuals with AB and BB genotypes in first parity（P0.05）,the total number born and number weaned of individuals with AA genotype were higher than those of individuals with AB and BB genotypes in later parities（P0.05）,weaning weight of litter of individuals with AA and AB genotypes were higher than those of individuals with BB genotype in later parities（P0.05）.On the whole,reproduction traits of three PvuⅡ polymorphisms of ESR gene showed the tendency of AA AB BB in Sutai pigs.
