Abstract. To compare quality traits of longissimus lumborum muscle of three genotypes, 20 White Mangalica (WM), 20 crossbred Duroc  ×  White Mangalica (DWM) and 20 Large White (LW) pigs were allotted to the same indoor rearing and feeding conditions. Crossbred and LW pigs grew faster than WM pigs reaching 150 kg on average 168 and 288 days before WM, respectively. Meat from WM pigs had the highest intramuscular fat content and darkest and reddest colour; crosses were at an intermediate position, with significant differences among all genotypes. In addition, ultimate pH, water-holding capacity and iron content were significantly the highest in meat from WM pigs, compared to the other two genotypes. Crossing WM with Duroc had a significant effect on individual fatty acid content of meat. However, the sum of saturated, monounsaturated and polyunsaturated fatty acids remained unchanged. WM and DWM pigs had significantly more tender meat than LW pigs. Monounsaturated fatty acids (MUFAs) were most abundant, followed by saturated (SFAs) and polyunsaturated fatty acids (PUFAs) in meat from all animals. Meat from WM and DWM pigs had a significantly higher percentage of MUFAs and significantly lower percentage of SFAs than LW pigs.
