Marker-Assisted Breeding for Fusarium Head Blight Resistance in Spring Wheat Grant uri icon

Overview

abstract

  • This project addresses a disease of importance nationally and internationally which is likely to become an increasing problem for growers in Idaho and some areas in Pacific Northwest (PNW) because of the increasing corn production, reduced tillage, and changing climate. Currently, most virtually grown cultivars in Idaho and PNW are susceptible to FHB. Developing FHB resistance in Idaho and PNW wheat cultivars will reduce or eliminate future costs of disease control using fungicides when epidemic occurs. Molecular marker-assisted selection will accelerate breeding of FHB resistance. Novel QTL/markers associated with FHB resistance in an adapted soft white spring wheat cultivar UI Stone will be identified in a mapping population derived from a cross between UI Stone and a susceptible soft white spring wheat cultivar Alturas. The new identified and existing markers all will be used in selecting of FHB resistance. The approach leverages recent advances in wheat marker development and resources at the USDA-ARS regional genotyping laboratory to apply marker assisted breeding to the problem.
