Genetic resistance to Fusarium head blight (FHB), caused by Fusarium gramin
earum, is necessary to reduce the wheat grain yield and quality losses caus
ed by this disease. Development of resistant cultivars has been slowed by p
oorly adapted and incomplete resistance sources and confounding environment
al effects that make screening of germplasm difficult. DNA markers for FHB
resistance QTLs have been identified and may be used to speed the introgres
sion of resistance genes into adapted germplasm. This study was conduct ed
to identify and map additional DNA markers linked to genes controlling FHB
resistance in two spring wheat recombinant inbred populations, both segrega
ting for genes from the widely used resistance source 'Sumai 3'.
