Abstract: The polymorphism of BMPR-IA gene in two high fecundity sheep breeds Fat-tailed sheep and Small Tailed Han sheep,one low fecundity sheep breeds Yuxi Fat-tailed sheep was studied by PCR-SSCP method to explore the influnce of this gene on fecundity of henan landrance sheep breeds.The results showed that:Two genotypes of BMPR-IA including AA and AB were detected.Frequency of AA genotype,AB genotype in Small Tailed Han sheep and Fat-tailed sheep were 0.525 and 0.778,0.475 and 0.222 respectively.A allele frequency and B allele frequency in Small Tailed Han sheep and Fat-tailed sheep were 0.738 and 0.889,0.262 and 0.111 respectively.While only AA genotype was detected in Yuxi Fattailed sheep.This study provide reference for exploring high fecundity mechism of Henan landranee sheep breeds at molecular level.

Key words: Fat-tailed sheep, Small tailed han sheep, BMPR-1,4 gene, PCR-SSCP
