This study was conducted to evaluate the phenotypic profiles, genetic and non-genetic effects on wool production traits in 588 German Angora rabbits maintained at Angora Rabbit Breeding Farm, Kandwari (Himachal Pradesh) from 2000 to 2007. The data were analysed by Harvey’s least-squares method of fitting constants. The overall least squares means were 58.77 ± 35.10 g, 169.77 ± 30.38 g, 181.00 ± 21.30 g, 184.73 ± 23.49 g and 594.22 ± 67.13 g for wool yield at first, second, third, fourth clip and annual wool yield, respectively. Year and season of birth significantly affected wool yield at first, third, fourth clip and annual wool yield; however, wool yield at second clip was significantly affected only by year of birth. The heritability estimates for wool yield at different clips and annual wool yield were low to moderate. Hence, improvement of these traits can be attained through better managemental practices, since there is little scope for genetic improvement of the traits through selection. The genetic, phenotypic and environmental correlations among the wool production traits were low to high in magnitude and positive in direction, which indicate that there is possibility of simultaneous improvement of the wool traits.
