During last decades, the identification of genes controlling productive traits has been a major goal in animal breeding. Recent availability of a high number of single nucleotide polymorphisms (SNPs) and genotyping platforms has allowed the identification of polymorphisms associated with growth, fatness, meat quality, disease resistance and prolificacy in pigs. However, most of these associations have not been probed in Iberian pigs, mainly because most of the polymorphisms are fixed or at low frequency in this breed. In this work a panel of 96 informative SNPs has been tested for association with growth, carcass, meat and fat quality traits in Iberian pigs from the Torbiscal strain. The panel was selected from the PorcineSNP60 BeadChip genotype information, taking into account the polymorphism level in Iberian breed and the location in the pig genome, in order to cover three economically interesting regions on chromosomes 4, 6 and 12. A total of 183 castrated male pigs were genotyped. Significant effects on the different traits were observed for several SNPs located in the three candidate regions. This approach could be useful for the identification of genetic markers and the design of valuable genetic tests to complement genetic evaluations for Iberian pig's selection.
