The factors of animal production level increase are feeding and keeping of animals, but the most important one in selection process intensification aimed on creation of high-productivity genotypes of swine. Because of pork producing level increase connected with animals' quality development, the ways of swine's gene resource increase are recovered. Duroc breed is one of the best paternal component and have got wide use in selection and hybridization processes in the republic of Belarus. The research results on the study of reproductive, fattening and meat qualities of pigs of Duroc breed at different selection methods of parental pairs are presented in the article. Reproduction qualities of female swine of Duroc breed during in-linear and cross-linear hybridization are analyzed. Fattening qualities of the young animals of Duroc breed born during different variants of hybridization are evaluated. Meat qualities of Duroc youngsters got during different types of hybridization are estimated. The effect of combination correlation of parental pairs on reproductive, fattening and meat performance of progeny is established. Perfect selection variants promoting improvement of productive qualities are identified.
