The Kansas State University wheat breeding program has been
breeding for FHB resistance for more than 20 years. Identification and
deployment of native resistance in the variety ‘Everest’ was a significant step
toward improved management of disease but progress beyond the Everest level of
resistance has been difficult. Phenotypic screening nurseries have facilitated
the transfer of additional resistance from outside the hard winter wheat gene
pool. Specifically, resistance derived from the soft wheat ‘Truman’ has been
useful, but combining resistance with agronomic performance has been
challenging. Recent results indicate a step change in the level of
resistance with the best materials having 3 percent symptomatic spikelets compared to Everest at 20%. Materials are still in early generations, therefore agronomic performance
has not be fully evaluated. However, visual phenotypes are superior to previous
iterations. Additional sources of resistance are still needed. An effort to
transfer resistance from Aegilops tauschii will be described. Future
strategies for improvement of FHB resistance in the KSU wheat breeding program
will also be discussed.
