Screening wheat lines for Fusarium head blight resistance
Wheat lines being screened for resistance to Fusarium head blight (FHB) on an experimental plot at CIMMYT’s headquarters at El Batán, Mexico, showing various levels of symptoms (manifest as necrosis of heads). The disease has been encouraged by spray inoculation with Fusarium graminearum spores (teleomorph Gibberella zeae) and mist irrigation. 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).
