Wheat cultivars (Stoa, MN87150, SuMai-3, YMI-6, Wheaton) and barley cultivars (Robust, Excel, Chevron, M69) were inoculated in the field with isolates of Fusarium graminearum and F. culmorum. The disease (Fusarium head blight) kernels were analyzed for deoxynivalenol (DON), 15-acetyldeoxynivalenol (15-ADON) and nivalenol (NIV). F. culmorum produced all three trichothecenes on all cultivars tested whereas F. graminearum only produced DON and 15-ADON. There was no well defined correlation between DON production in the host and resistance although the data tended to favor SuMai-3 as having definitive resistance to both F. graminearum and F. culmorum.
将小麦品种（斯托亚、MN87150、苏麦3号、YMI - 6、惠顿）和大麦品种（罗布斯塔、Excel、雪佛龙、M69）在田间接种禾谷镰刀菌和燕麦镰刀菌的分离株。对感染病害（镰刀菌穗腐病）的籽粒进行脱氧雪腐镰刀菌烯醇（DON）、15 - 乙酰脱氧雪腐镰刀菌烯醇（15 - ADON）和雪腐镰刀菌烯醇（NIV）分析。燕麦镰刀菌在所有测试品种上均产生了这三种单端孢霉烯族毒素，而禾谷镰刀菌仅产生DON和15 - ADON。尽管数据倾向于表明苏麦3号对禾谷镰刀菌和燕麦镰刀菌都具有明确的抗性，但在寄主中DON的产生与抗性之间没有明确的相关性。
