以1个丹麦家猪家系为试验材料,对猪全基因组单核苷酸多态性(SNP)标记筛选与猪肉pHI 和pHU值有关的QTL.结果发现在6号染色体上存在一个显著影响pHI 和pHU值的QTL,与pHI显著相关的QTL的效应为2.6%~8.5%,其中单倍型FLJ30670的贡献率最高,为8.5%,与pHU显著相关的QTL中效应为2.1%~4.3%,都低于pHI有关的效应,其中效应最大的单倍型为FUT1,贡献率为4.3%,估计是猪肉24 h酸度变化受外界其他因素的影响更多.

Pork pH value is an important trait related to meat quality, the trial has screened the SNP-QTL associated with pork pHI and pHU from genome wide SNP screening in a Danish swine predgree. The result indicated there was a QTL on chromosome 6 which was associated with pork pHI and pHU value signficiantly. Effect value of QTL associated with pHI significantly was between 2.6%-8.5%, FLJ30670 locus had a strong effect on pHI and it took 8.5% of total variation, while effect value of QTL associated with pHU significantly was 2.1%--4.3%, all of which were lower than pHI related effect of them, the FU...
