Effects of Head Blight Caused by<i>Fusarium culmorum</i>on Toxin Content and Weight of Wheat Kernels

Abstract

Ten winter wheat genotypes were inoculated with three Dutch strains of Fusarium culmorum (IPO 39-01, IPO 348-01 and IPO 436-01). Seed samples were anlyzed for several trichothecene mycotoxins and zearalenone. Deoxynivalenol was detected in concentrations ranging from 0 to 48 mg/kg. Interactions between strains and genotypes were observed for head blight and kernel deoxynivalenol content. Path anlysis suggested a relation between deoxynivalenol and kernel weight reduction
