Investigations were carried out in order to study some physical traits (wool length, diameter, tearing force and elongation) of hair types at 2nd, 3rd and 4th shearing. To improve our production some German bucks were bought, and we would like to study if they had any effect on the wool production of progeny. Wool production increased with body weight and number of harvest. Compared to the previous shearings the values of physical traits of hair types from the 2nd shearing were significantly increased. The highest correlation value was found between thinnest diameter and tearing force. Progeny from German bucks were heavier and produced a slightly longer wool with more bristles.
