Localization of whirling disease resistance QTL on rainbow trout chromosome Omy9. Map positions and LOD scores are based on combining four outbred F₂ mapping families into a single interval mapping QTL analysis using the software MapQTL 6. The combined family 95% genome-wide LOD significance threshold value is 6.6 (dashed constant line). All markers with LOD scores>20 are shown in bold. The QTL (termed WDRES-9) has a LOD peak of 123.3 and the 95% confidence interval is a 1.85 cM region including marker BX310634.
