Abstract | Crown rot (casual agent Fusarium pseudograminearum) is a fungal disease of major significance to what cultivation in australia. A doubled haploid wheat population was produced from a cross between line 'W21MMT70', which displays partial seedling and adult plant (field) resistance to crown rot, and 'Mendos', which is moderately susceptible in seedling tests but partially resistant in field trials. Bulked segregant analysis (BSA) based on seedling trial data did not reveal markers fro crown rot resistance. A framework map was produced consisting of 128 microsatellite markers, four phenotypic markers, and one sequence tagged site marker. To this map 331 previously screened AFLP markers were then added. Three quantitative trait loci (QTL) were identified with composite interval mapping across all of the three seedling trials conducted. These QTL are located on chromosomes 2B, 2D and 5D. The 2D and 5D QTL are inherited from the line 'W21MMT70', whereas the 2B QTL is inherited from 'Mendos'. these loci are different from those associated with crown rot resistance in other wheat populations that have been examined, and may present an opportunity for pyramiding QTL to provide more durable resistance to crown rot. |
