Latest results in breeding winter wheat for resistance to Fusarium Head Blight in the Zagreb Bc Institute

Abstract

Fusarium head blight (Fusarium graminearum Schw.) is one of the most dangerous fungal diseases in wheat production decreasing grain yield up to 50% or more what depends on both environmental factors and genotype. Testing of inoculated artificially new Bc winter wheat lines for their resistance to FHB was the objective of the study.In 2008 and 2009 two and five lines of tested 12 new ones respectively were shown to be more resistant than Sana cultivar used as a standard. Majority of the winter wheat lines exceeded level of resistance standing out by Bc 7 and Bc 1 and Bc Lira variety as the highest yielding variety was registered by CCVR in 2009.

Evaluation of Inoculation Methods for Determination of Winter Wheat Resistance to Fusarium Head Blight

“…In the Bc Institute's winter wheat breeding program, screening of elite breeding lines for FHB resistance using the spray method of inoculation with Fusarium isolates serves as efficient criterion for final selection for registration purposes [30][31][32]. In the present study, an alternative inoculation method for screening FHB resistance in wheat, known as deployment of Fusarium-infected maize stalks, was compared with the standard spray method and natural infection.…”
