摘　　要：测定了长蓝参考家系F2代个体的肉色、大理石纹、pH值和系水力4个肉质性状,同时测定了6号染色体的23个微卫星DNA标记,将不同基因型与4个肉质性状进行方差分析与多重比较.结果表明:肉色与大理石纹、pH值、系水力间的相关系数分别为-0 322、0 419、0 468,pH值和系水力间的相关系数最高,为0 737,差异极显著;MN006座位与影响pH值性状的QTL连锁,加性效应为0 108,MN004座位与影响大理石纹性状的QTL连锁,加性效应为0 125.Pork quality traits, color, marbling, pH and waterholding capacity, were measured in F2 population of Landrace×Lantang swine reference family by genotyping 23 microsatellite DNA markers at chromosome 6. The results showed that the correlation coefficients between pork color and marbling, pH, waterholding capacity were -0322, 0419,0468 respectively,and 0.737 between pH and waterholding capacity. The additive effect of QTL linkage with D allele at MN006 locus is 0.108 for pH, and the additive effect of QTL linkage with A allele at MN004 locus is 0.125 for marbling.
