Fusarium head blight resistance genes, Fhb1 (for Type-II resistance), Fhb2 (Type-II), and Fhb5 (Type-I plus some Type-II), which originate from Sumai 3, are among the most important that confer resistance in hexaploid wheat. | Genetic factors affecting Fusarium head blight resistance improvement from introgression of exotic Sumai 3 alleles including Fhb1 Fhb2 and Fhb5 in hard red spring wheat
