The aim of this thesis was to evaluate the genetic progress in the breeding of pietrain pigs. The evaluation was conducted on the indicators of reproduction and production traits. Data for monitoring progress were derived from the hybridization program of the Czech Republic for the period 2000 -- 2014. For the evaluation were used 2865 births, 2368 values for gilts and 2387 for young boars. The results show that the level of reproduction has increased from 8,70 to 9,30 live born piglets (+6.98%). Growth ability is worse, the decrease in the average daily gain in gilts is from 606 g to 557 g (--8.08%) and the decrease in young boars is from 647 g to 626 g (--3.25%). During the reporting period the conformation breed increased for gilts from 62.1 % to 65.2 % lean meat (+3.32%) and for young boars from 63.8 % to 66.2 % lean meat (+3.76%). According to the breeding goals for 2020 both of the monitoring indicators did not reach the desired values. In breeding of this breed will be needed to improve especially the growth ability.
