We talk with Dr Brett Carver, wheat breeder at Oklahoma State University, about the unique challenges of the 2024 wheat crop in the southern Great Plains. The early and severe outbreak of stripe rust disease, which Carver calls the "worst" he's seen, sets the stage for a candid conversation about the complexities of wheat breeding.

Despite the significant disease pressure, some areas achieved remarkable yields. Carver also reflects on how this challenging season offers valuable insights for the breeding program, describing it as a "gift" for identifying varieties with allseason resistance to stripe rust.

The need for fusarium head blight resistance and the potential role of a newly released scab-resistant line

"Butler's Gold" variety's early maturity and its significance for double-cropping systems

Breeding targets, including harder wheat kernels with improved gluten and higher fiber content for health-conscious consumers

Efforts to increase the fiber content of milled wheat flour and changing consumer perceptions toward wheat

The timing of grazing for dual-purpose wheat and the potential for dedicated dual-purpose varieties

Breeding for disease resistance beyond stripe rust, such as Septoria nodorum
