The polymorphism of genes CAST249, CAST638; positions N30T, S52G, I199V, R200Q in the PRKAG3 gene; MC4R, IGF2, CCKAR the three-breed hybrids of pigs was studied. An analysis of the qualitative indicators of fattening productivity experimental groups was carried out. The linear-regression analysis of qualitative indicators of fattening productivity showed signifi cant additive, dominant and both effects of the CAST638 gene to the slaughter weight, age at weight of 100 kg and the average daily gain. Trends were identifi ed considering the relationship between the slaughter weight and genes PRKAG3 (in position S52G) and CCKAR, age at weight of 100 kg and genes MC4R and CCKAR, the thickness of backfat and gene CAST638, the average daily gain and gene MC4R, the mass ham and gene PRKAG3 (in position N30T), diameter of longissimus dorsi and gene CCKAR.
