Abstract :Parameters of some factors affecting body weight at shearing and some wool production traits of Akkaraman, Awassi and Awassi x Akkaraman crossbreed sheep raised in Ereğli Sheep Breeding Station were estimated by evaluating the records of 452 sheep relating to 2001 and 2002 years. Least square means for Akkaraman, Awassi and Awassi x Akkaramaninsert ignore into journalissuearticles values(F1 x AwB1); crossbreed sheep respectively were de-termined as 1.75 kg, 2.13 kg and 2.08 kg for greasy fleece weight insert ignore into journalissuearticles values(GFW);; 16.97 cm, 15.94 cm and 15.07 cm for fiber length insert ignore into journalissuearticles values(FL);; 52.40 deg/mm, 48.33 deg/mm and 47.89 deg/mm for degree of curl insert ignore into journalissuearticles values(DC);; 31.94 , 30.69  and 30.76  for fiber diame-ter insert ignore into journalissuearticles values(FD); and 54.72 kg, 52.85 kg and 53.85 kg for body weight at shearing insert ignore into journalissuearticles values(BW);. Effects of age on GFW and BW was signifi-cant insert ignore into journalissuearticles values(P<0.01);. Year only had a significant effect on BW insert ignore into journalissuearticles values(P<0.01);. Effects of Genotype and sex on LW and GFW were also significant insert ignore into journalissuearticles values(P<0.01);. Repetabilities for Akkaraman, Awassi and Awassi x Akkaraman crossbreed sheep respectively were esti-mated as 0.85, 0.84 and 0.82 for GFW; 0.62, 0.75 and 0.82 for BW.
