Interpretive Summary: Fusurium head blight (FHB) is one of the most destructive diseases in wheat. To search for new resistance sources, a mapping population derived from the cross of wheat cultivars Chokwang and Clark was characterized with molecular markers. Chokwang is a highly FHB resistant cultivar from Korea. One resistance gene and linked markers were identified on chromosome 5DL from Chokwang. Another two genes were identified on 4BL and 3BS. The gene on 3BS in Chokwang is a minor gene and most likely a different allele of the 3BS gene in Sumai 3. Pyramiding resistance genes from various sources may enhance FHB resistance in wheat cultivars.
