Abstract. The analysis included 399 Polish Noble Half-bred stallions registered in Vol. 2 of the Studbook of the Polish Noble Half-bred horses (PKSP) and 75 CzechWarm-blood stallions registered in the Studbook of the CzechWarm-blood horses (Kčt). No significant differences were found in mean exterior measurements between the Polish Noble Half-bred and the CzechWarmblood stallions. In both studbooks, the dominant sire breeds are local breed getters, i.e. the Wielkopolski and the Polish Noble Half-bred stallions in the PKSP studbook and the Czech Warm-blood ones in the Kčt studbook. Similar situation is being observed when analysing the ancestry pedigree of their dams; in both breeds, local breed mares were most frequently selected as female breeding material.
