Abstract
176 North Caucasus Mutton-Wool ewes were grouped according to fleece weight as follows: (1) 3.4 kg; (2) 2.9 kg and (3) 2.6 kg, and were inseminated with semen from rams averaging fleece weights of (1) 7.5 kg, (2) 6.8 kg or (3) 6.1 kg. For 14-month-old daughters of parents mated assortatively for fleece weight (1+1, 2+2 and 3+3) and for matings 2+1 (intermediate sires with best dams), 3+1 and 3+2, fleece weight averaged 5.12, 4.99, 5.00, 5.06, 5.17 and 5.15 kg, resp., clean wool yield 3.04, 3.19, 3.28, 3.27, 3.28 and 3.15 kg, staple length 15.1, 14.7, 14.3, 14.4, 15.1 and 15.4 cm, and body weight 43.2, 44.0, 44.1, 43.3, 43.9 and 44.2 kg. Differences between groups in fleece weight were not significant.
