The aim of this thesis was to inform about pig genotypes and sex influencing selected traits of meat quality. Several combinations of the final pig hybrids (CLxCLW)xCLW-sire line, (CLxCLW)x(CLW-sire line x Pn), (CLxCLW)x(DxPn) and (CLxCLW)x(CLW-sire line x D)with balanced sex ratio (barrows : gilts). The highest intramuscular fat content (2,15 %) has been detected in the (CLxCLW)x(CLW-sire line x D) hybrid combination; the barrows (1,78 %) reached a higher ratio compared to gilts (1,42 %). There were detected only small differences in traits pH45 and pH24, there was not even found any difference between the two sexes. The lightest meat (% remission) has been proven by the (CLxCLW)xCLW-sire line combination with no significant difference between sexes. There have been quite similar values between the sexes and even hybrid combinations, concerning the meat lightness (L*). The drip loss was highest in the (CLxCLW)x(DxPn) combination with only fractional difference between sexes. In the shear force has been detected the lowest value in the (CLxCLW)x(CLW-sire line x Pn) combination with a small difference between barrows and gilts. From the genotype aspect were confirmed statistically important differences in the following traits: intramuscular fat content, meat lightness (% remission), drip loss and shear force. From sex aspect, only differences in intramuscular fat content were found.
