Winter wheat is an economically significant commodity in the Pacific Northwest (PNW) and one of the few crops whose yields are impacted by snow mold, a fungal disease with multiple causal agents. To date, cultural controls and tolerant varieties have remained the best methods to manage the disease. However, since initial breeding efforts began in the 1940s, genetic diversity for snow mold tolerance has remained limited in local varieties. The winter wheat landrace PI 173438 has been evaluated for snow mold tolerance in the PNW but has not yet been used in local breeding programs. This project investigated PI 173438 for novel quantitative trait loci (QTL) associated with snow mold tolerance and recovery using a doubled haploid mapping population developed from a cross between PI 173438 and a susceptible Washington State University breeding line WA 8137. In the QTL analysis using linkage mapping, six QTL were found in association with snow mold tolerance traits, with five of the QTL originating from PI 173438. A QTL was found on chromosome 1D that has not been reported before. The remaining QTL occurred on chromosomes that were previously reported to have snow mold tolerant QTL, some of which may be identical. Several of the linked markers to these QTL were suitable for testing via marker-assisted selection using a KASP assay on two separate, but related populations. This revealed no significant differences amongst the three or four QTL that could be tested. Such results continue to indicate the complexity of snow mold tolerance and breeding for this trait using molecular markers. PI 173438 has also been found to have resistance to other diseases and may possess other useful genetics for future studies of other biotic stresses or economically important traits. The PI 173438/WA 8137 doubled haploid mapping population was characterized and submitted to the NLGRP to aid in future research.
