Crown rot caused by Fusarium pseudograminearum (teleomorph: Gibberella coronicola ) is a serious disease of wheat. A simple and reliable method for assessing this disease would enhance our capacity in identifying resistance sources and developing resistant wheat cultivars. In searching for such a method, several inoculation techniques were tested. One technique, soaking 1‐ to 4‐day old seedlings in fungal spore suspension, produced consistent and severe crown rot symptoms. Glasshouse testing of several wheat genotypes using this method produced results that agreed well with previously established field ratings for crown rot disease, suggesting that this assay can be conveniently employed for screening of wheat genotypes for crown rot resistance.
