Fur quality in mink (Neovison vison) is a composite trait, consisting of e.g. guard hair length, guard hair thickness and density of wool. A genome wide QTL search was performed to detect QTL for fur quality traits in mink. Here we present the results of QTL analyses for guard hair length, guard hair thickness and density of wool. Data from an F2-cross was analysed across fourteen chromosomes using 100 microsatellites as markers with a spacing of approximately 20 cM. The two lines used for the F2-cross were Nordic wild mink and American short nap mink. In total 1,083 animals (21 wild type, 25 short nap, 103 F1 and 934 F2) were marker typed and recorded for the three presented fur quality traits. For the QTL-analyses a regression analysis implemented in QTL Express software was used. Evidence was found for the existence of QTL for guard hair length, guard hair thickness and density of wool on 8 out of 14 autosomes. There was evidence for QTL for guard hair thickness on chro¬mosomes 1, 2, 3, 6, 7, and 8, guard hair length on chromosomes 1, 2, 3, 4, 6, 7, 8, and 11 and wool on chromosome 7. On chromosomes 2, 6 and, 7 QTL for guard hair length and guard hair thickness were located near each other. This indicates that variation in the two traits to some degree may be under the control of the same genes.
