Abstract：The 5 microsatellite DNA loci linked with PPAR (peroxisome proliferator activated receptor) gene were selected from the published genetic map of chromosome 13 in pig, and polymorphisms of these microsatellites in 100 samples from Sutai pigs (Duroc × Erhualian) were detected. The results revealed that the number of alleles were 6~9, heterozygosity 0.59~0.81, polymorphism information content 0.51~0.76, the correlation coefficients between back fat thickness(BFT) and tenderness, water-holding capacity(WHC), and intramuscular(IMF) were –0.358, 0.020 and 0.311, respectively, and there existed significant correlations between BFT and tenderness, IMF (P<0.01). Moreover, effects of S0021, SW937, SW482, S0222, and S0281 on meat quality traits were analyzed with PROC GLM of SAS. Results showed that the effect of SW482 on BFT was significant (P<0.05) and SW937 on WHC reached a significant level at P<0.01. S0222, S0281 and S0021 had no significant effect on the two selected meat quality traits(P>0.05).
