The aim of this study was to compare the characteristics of wool from Arkhamerino, Ghezel and Moghani crosses. In order to evaluate fleece characteristics, wool samples were obtained from 176 ArkhamerinoxGhezel (ARG) and 80 ArkhamerinoxMoghani (ARM) F1 crosses (aged 9-15 months). Samples were taken in spring from right mid-side during a period of three years (1999-2001). Fleece characteristics including fiber diameter (FD), fiber diameter variability (CVd), staple length (SL), kemp (KP) and medulation (MP) percentage were analyzed. Average fleece characteristics of FD, CVd, SL, KP and MP for ARG were 27.11±0.25|i, 36.6±0.59%, 11.94±0.32 cm, 1.56±0.35% and 7.33±0.72% and for ARM were 26.18±0.46ji, 36.16±0.97, 10.95±0.39cm, 2.27±0.29 and 8.82±0.91, respectively. Data were analyzed for genotype, sex, birth year and birth type by general linear model (Glm) and the age of sheep (or lambs) considered as a cofactor in statistical model. The genotype had a significant (P<0.05) effect on FD and ARM crosses had produced finer wool. Sex significantly (P<0.05) affected FD, CVd and SL. Females had finer wool with higher CV and longer staple. Year of birth had significant (P<0.05) effect on SL (P<0.05). F1 crosses which were born in 2000 had shorter staples. The interaction of genotype and the year of birth significantly (P<0.05) affected CVd. Type of birth had no significant effect on fleece characteristics.
