Hexaploid spring wheat ( Triticum aestivum ) may exhibit significant crown rot disease responses to infection by Fusarium pseudograminearum , with a range of susceptibility levels available in commercial cultivars. Dry conditions during grain-fill may lead to the expression of prematurely senescing...
