Aspects of resistance to fusarium head blight caused by Fusarium culmorum in wheat

摘要: In the Netherlands, Fusarium head blight of wheat is predominantly caused by culmorum . A low infection level leads to important yield losses and contaminates grain with mycotoxins, particularly deoxynivalenol. This mycotoxin suggested have toxic effects on plant. Genetic variation for resistance appears be very large. The quantitative; complete does not exist. estimated number genes in studied winter wheats was small, individual had large inherited mainly additive. Transgression observed progenies. It possible select plants a single plant base. No indications were found strain-specific resistance. Systemic fungal growth stems this trait also demonstrated. There potential breeders develop cultivars high blight.
