摘　　要：从已公布的猪13号染色体连锁图谱中选择与PPAR基因连锁的7个微卫星座位,在苏太猪群体中对这些位点进行群体遗传学特性分析。研究结果表明:各位点等位基因数为6～9个,杂合度为0.59～0.81,多态信息含量为0.51～0.76。方差分析结果显示:微卫星位点S0021对pH值、SW937对系水力影响均达到极显著水平(P<0.01);位点S0293对嫩度、SW482对背膘厚也有显著影响(P<0.05);其他位点S0222、S0281和SWR2054对各性状影响均未达到显著水平(P>0.05)。In this reseanch,7 microsatellite DNA loci linked with PPAR 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) populations were detected.Results revealed that the number of alleles were 6~9,heterozygosity 0.59~0.81,polymorphism information content 0.51~0.76.Effects of S0021,SW937,SW482,S0222,S0293,S0281 and SWR2054 on meat quality traits were analyzed with PROC GLM of SAS.Results showed that the effects of S0021 on pH value and SW937 on water-holding capacity reached a significant level at P<0.01 respectively.The effect of S0293 on tenderness and SW482 on BFT were also significant (P<0.05).S0222,S0281 and SWR2054 had no significant effect on the 7 selected meat qualitytraits (P>0.05).
