Abstract: The exon 2 of SLA-DQB gene in Sutai pigs was analyzed by PCR-RFLP method, the results showed that the exon 2 of SLA-DQB gene digested by restriction endonuclease RsaⅠ and HaeⅢ could be divided into four kinds of genotypes and three kinds of genotypes in Sutai pigs respectively. The results of χ2 indicated that the frequencies of patterns digested by RsaⅠand HaeⅢ fit with Hardy-Weinberg equilibrium in Sutai population. Four kinds of combined patterns were observed in Sutai pigs. The correlation between these combined patterns and the reproductive performances of Sutai pigs was analyzed, the results showed that reproductive performances (the total litter, number of viable pigs, litter weight at birth, number of ablactation pigs and litter weight after ablactation in the third litter) of Sutai pigs with BBEE combined pattern were significant higher than those with AADD combined pattern, also higher than the pigs with ABDE combined pattern and ACDE combined pattern, but were no significant difference in reproductive performances between pigs with AADD combined pattern and the pigs with ABDE and ACDE combined patterns.
