Improving pork quality is a high priority and a challenging task for the current pig industry. Because of the complicated properties of meat quality, breeding innovations for improved meat quality meat traits requires more knowledge of modern molecular and quantitative genetics than traditional breeding approaches. On the basis of previous quantitative trait loci (QTL) mapping results of our research group, additional SNPs markers were further mined and QTL fine mapping was implemented. We continue to search for additional markers to explain the meat quality effects seen on chromosome 17.
