Corteva will launch hybrid wheat in the Hard Red Winter market class in Fall 2027. Thanks to its unique, non-transgenic sterility system, hybrid seed can now be produced reliably and at scale and independent of genetic background. This
breakthrough eliminates production challenges and leverages hybrid vigor to set a new standard for wheat yield in the U.S. Internal trials show that the yield advantage of hybrids is +10% greater than varietal checks, and up to 20% higher
under drought stress. Fusarium head blight (FHB) resistance is also an important focus in Corteva's breeding programs. For example, in the Soft Red Winter market class, FHB resistance is one of the competitive advantages of Corteva (Pioneer) commercial varieties; progress for FHB resistance is being achieved through a combination of whole genome predictions strategies and selection for major FHB genes. FHB screenings are conducted in field nurseries, controlled conditions in greenhouse, and in collaboration with universities.
