Abstract: 5 pairs of primers were designed to identify SNPs in 3′-regulatory region of myostatin gene in 3 geese breeds, and the relativity of SNPs and slaughter characters was also analyzed. And the resulted two SNPs were detected, which were A88G and G353T. Population genetic analysis indicated that there were EE and EF genotypes in 88bp locus, and E allele was a preponderant one. The frequency of EF genotype was especially high in Yangzhou geese (0.55), but very low in Wanxi White geese (0.03). In 353bp locus, three genotypes, GG, GH and HH were detected .The frequency of GG was the highest and that of HH was the lowest in 3 geese groups. The relativity analysis showed, individuals with EF had higher slaughter performances than those with EE. For leg muscle weight(LMW) and leg muscle percent(LMP) , individuals with GG were significantly higher than those with HH in Yangzhou geese and Wanxi White geese (P﹤0.05).
