Abstract: 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（P<0.05）, 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（P<0.05）, weaning weight of litter of individuals with AA and AB genotypes were higher than those of individuals with BB genotype in later parities（P<0.05）. On the whole, reproduction traits of three PvuⅡ polymorphisms of ESR gene showed the tendency of AA> AB > BB in Sutai pigs.
