Abstract:

The purpose of this research was to find microsatellite markers stronger linked to litter size and birth weight of sheep.Six polymorphic Ovine brain and ovary derived EST-SSR loci were measured in 196 F2 animals from a German Merino×Chinese Merino sheep,then the genetic polymorphism of group and the correlation between microsatellite markers and litter size and birth weight were analyzed.The results showed that the loci had rich polymorphism and 23 alleles were detected among 6 loci in the group.The range of heterozygosity(H) was 0.585 1 to 0.776 6,and the polymorphism information content of all loci (PIC) were higher than 0.5.114719622,114720463,114722561 loci were eligible for Hardy-weinberg equilibrium.The results indicated that 6 loci had significant effect on birth weight and litter size.The locus of 114719418 related with average birth weight and total birth weight,114720463 and 114758122 loci with total birth weight and litter size,114719622 and 114722561 loci with total birth weight,47952182 locus with litter size.It is suggested that these 6 loci probable had high linkage with genetic locus of litter size and birth weight traits.
