%X Estrogen receptor (ESR) can regulate the synthesis of oestrogen and affect the reproduction of swine.The relationship between Pvu II polymorphisms at estrogen receptor gene and litter size was analyzed in Laiwu breed and Landrace breed by candidate gene method.The results were shown that 56bp of Pvu II polymorphisms was the same as the beginning sequence of 3 7kb of RFLP.The distribution of Pvu II polymorphisms also could not prove that B gene was a superior gene,and there was no decisive effect of 3 7kb band on litter size in pigs.
