Mapping of quantitative trait loci (QTL) affecting fur quality traits (guard hair length, guard hair thikness, and density of woll) was performed in a 3-generation population (F2-design). In the parental generation, Nordic wild mink were crossed reciprocally with American short nap mink. Twenty one wild mink were mated to 25 short nap mink. In the F1-generation 103 mink were mated. 934 mink were obtained in the F2-generation. The mink were genotyped using 104 microsatellites covering all 14 autosomal chromosones. The marker spacing was approximately 11 cM. Recording of fur quality traits were wade on all genotyped mink by Kopenhagen Fur. The QTL analyses were performed by least square regression implemented in the software Grid QTL. Evidence was found for QTL for the fur quality on eight autosomal chromosomes (LOD score >3.0). QTL were detected for guard hair thickness on chromosomes 1, 2, 3, 4, 6, 11, and 13, for guard hair length on chromosomes 2, 3, and 6 and for wool density on chromosome 6, 7, and 13. Similar locations of QTL for guard hair length and guard hair thickness on chromosomes 2, 3, and 6 suggest that these traits are in part under the influence of the same genes
