The study was conducted on 19 samples of wool of Żelaźnieńska Sheep and 28 samples of wool of Corriedale Sheep. The thickness of fi bre and rendement were examined. The color of wool were measured by colorimetric technique. Basis of studies found a wider range of thicknes fi bre of Corridale Sheep and narrow range of thickness fi bre of Żelaźnieńska Sheep compared with the standards. Particular importance is to eliminate from the breeding primiparas Corriedale Sheep characterized by nominal thickness of fi bers 25 μm and less. Average nominal thickness of the fi bers were consistent with the cited standards. In Żelaźnieńska Sheep breed obtained, positive and highly signifi cant correlation coeffi cients of rendement and thickness to brightness (L*) and found a signifi cant correlation coeffi cient between rendement and the share of yellow color (b*). In Corriedale Sheep found positive and signifi cant statistical correlation coeffi cient between the brightness (L*) and nominal thickness. Correlations between traits characterizing the color of wool, and in particular the measurement of brightness (L*), to features such as the nominal thickness of the fi bers, indicate different trends occurring in Żelaźnieńska Sheep and Corriedale Sheep.
