The aim of the present investigation was to evaluate the effect of the implementation of RYR, ESR and FUT1 genes in marker assisted selection on the currently performed selection for own productivity. A total of 205 female and 32 male Danube White pigs were tested for polymorphism of RYR, ESR and FUT1 loci Blood samples were obtained from the orbital sinus. Genotypes were determined in the Laboratory of Applied Molecular Genetics according of loci - LAMGen at the Department of Genetics, Mendel University of Agriculture and Forestry in Brno, Czech Republic using PCRRFLP. Data from the phenotype test of pigs were analyzed including backfat thickness - CKL2 and age at 90 kg live weight depending on the genotypes of studied loci. The marker assisted selection for RYR, ESR and FUT1 genes, have no negative effect on phenotype test traits - backfat thickness and growth performance. For the FUT1 gene however, the relationship of the favourable A allele to the deposition of more backfat should be evaluated in a larger number of pigs, as in our study, we have observed such a tendency.
