Interpretive Summary: Molecular characterization of resistance genes to FHB in wheat and using molecular markers to select for these genes will aid in the development of FHB resistant cultivars. Most reported FHB resistance genes are from Sumai 3, a Chinese resistant cultivar, and its derivatives. Wangshuibai is a Chinese FHB-resistant landrace and is not known to be related to Sumai 3. A population of recombinant inbred lines (RILs) was developed from a cross of Wangshuibai and Wheaton and evaluated twice for FHB infection on spikes. Four FHB resistance genes were detected. One major gene near the end of chromosome 3BS explained 37.3% of the phenotypic variation. Other minor genes on 3BS, 7AL, and 1BL explained 7.4% to 11.9% of the phenotypic variation. The molecular markers closely linked to these FHB resistance genes can be used for stacking QTL from Wangshuibai and other sources to develop cultivars with transgressive FHB resistance.
