The aim of the observations was to characterize breeding performance of polish white landrace sows in pure breeding in crossing with boars pietrain x duroc and line 990 x pietrain breed. Results indicate that crossing of sows polish white landrace with boars of pietrain x duroc and line 990 x pietrain breeds gives positive effects in relation to breeding performance, primarily the number of piglets born in the litter. Piglets after boars line 990 x pietrain had higher body weight than piglets from boars pietrain x duroc during all rearing period.
