Abstract:

The University of Nebraska- Lincoln Small Grains breeding program has been addressing the need for FHB resistant varieties in wheat for over 20 years and has recently begun targeting improved resistance in our winter feed barley program. The disease can often be found in Nebraska small grain production fields, but usually at a low level of severity. Often, our dry climate prevents significant epidemics, but we have seen severe crop damage in 2007, 2008, 2015, and 2019. Our breeding program primarily relies on native resistance identified through phenotypic screening for both wheat and barley with selection optimized through genomic prediction. However, as interest in small grains production increases in FHB-susceptible southeastern Nebraska we are working with colleagues throughout USWBSI to increase major gene resistance in our germplasm.
