Summary The determination of genetic variability by means of molecular genetic markers FUT1 and ESR2 , and the evaluation of their associations with reproduction traits in population of Přeštice Black‐Pied sows have been implemented. A lower frequency of the allele FUT1 A than the frequency of the allele FUT1 G in the FUT1 gene was ascertained. In the ESR2 polymorphism, a higher frequency of the allele ESR2 A compared with the allele ESR2 B was determined. In the second to sixth litters as well as in the first to sixth litters, a significantly lower number of piglets born alive and number of weaned piglets from sows of the FUT1 A / FUT1 A genotype was found. Moreover, the homozygotes FUT1 G / FUT1 G significantly exceeded sows of the FUT1 A / FUT1 A genotype in the total number of born piglets in the first to sixth litters. No significant effect of the ESR2 polymorphism on reproduction was observed.
