The effect of own performance of meaty breed and/or combination boars on fattening, carcass and meat quality traits of their progeny was studied. Boar traits were tested in field conditions: average daily gain from birth to 100 kg live weight, average backfat thickness and lean meat content. Boars were mated with dams - crosses of LWxWM, WMxLW, WMxDU. Their progeny was tested (n = 10-26 per boar) at two different control stations (CS Bucany and/or Nitra). Progeny traits were: average daily gain in test (30-100 kg live weight), feed consumption per 1 kg gain, slaughter weight, backfat thickness, eye muscle area, proportion of prime meaty cuts, of ham, and at CS Nitra pH, el. conductivity and meat colour also. The effect of individual boar on progeny performance was different with regard to the control station. Significant differences in these traits between progeny of boars at CS Nitra were not found. However, significant differences (min. P0.05) in all the traits except for slaughter weight and eye muscle area between progeny groups at CS Bucany were found. Similarly, the effect of group of boars was very different in dependence on the control station. Progeny from a group of boars with better own performance at CS Bucany exceeded progeny from a group of worse tested boars (average daily gain +33 g, backfat thickness -2.1 mm, prime meaty cuts +2.34 %). Results from CS Nitra did not confirm the advantages of boars with better own performance. Several progeny traits were more influenced by individual dams (min. P0.05).
