Innoculating wheat with Fusarium graminearum for Fusarium head blight screening
A CIMMYT research assistant inoculates wheat with Fusarium graminearum spores (teleomorph Gibberella zeae) to test for resistance to Fusarium head blight (FHB), on an experimental plot at the center’s headquarters at El Batán, Mexico. A CO2-driven backpack sprayer is used to deliver a liquid inoculum of F. graminearum conidia at flowering, ensuring a high and consistent disease pressure. CIMMYT screens several thousand lines for FHB resistance every year. Resistant materials are the result of ongoing breeding efforts, and may be used further in CIMMYT’s breeding program or enter international nurseries like the Fusarium head blight screening nursery (FHBSN).
