The aim of our study was to quantify the influence of the fathers' genotype in RYR1 gene on the carcass of pigs. A total of 597 pigs originating from crossbreeds (Czech Large White x Czech Landrace) x Pietrain, fattened under common conditions of large capacity pig farm were slaughtered, weighed, measured and evaluated by FOM appliance. The slaughtered pigs were classified into groups of homozygous dominant genotype, heterozygous genotype and homozygous recessive genotype according to the father's genotype. The heaviest carcass and the highest muscling was reached by pigs with nn genotype which had the thinnest layer of meat at the same time. The highest fat thickness and carcass length was reached by pigs with heterozygous genotype and the lowest value of pH1. The differences between these qualitative characteristics were statistically significant among the groups. The obtained results suggest the possibility of using a suitable genotype of RYR1 gene to produce high quality commercial pigs.
