Data on fleece traits of Markhoz (Iranian Angora) goats were collected in March 1997. Traits studied were fiber diameter (FD), staple length (SL), greasy fleece weight (GFW) and number of crimps(C). The some
environmental factors and genetic effects on FD and SL were analyzed with Henderson mixed model equation (MME) methods. The least square means of fiber diameter and staple length were 33.65+0.49 micron and 15.46:t0.30 cm respectively. Herd significantly influenced FD and SL (P
of mentioned traits between herds in FD and SL were 8.5 micron and 7.24 cm
respectively. Color of animal had a significant effect on FD (P
correlation estimated for C-SL, C-FD, C-GFW, SL-FD, SL-GFW, and FD-GFW were 0.44, -0.22, 0.04, 0.37, 0.30, and 0.42 respectively. The
differeces between highest and lowest breedig value for FD and SL were 8 micorns and 5.14 cm respectively.
