Trichothecene genotype and genetic variability of Fusarium graminearum and F. cerealis isolated from durum wheat in Argentina

Fusarium head blight (FHB) is one of the most important fungal diseases affecting wheat worldwide and it is caused mainly by species within the Fusarium graminearum species complex (FGSC). This study evaluated the presence of FGSC in durum wheat from the main growing area in Argentina and analyzed t...

This study evaluated the presence of FGSC in durum wheat from the main growing area in Argentina and analyzed the trichothecene genotype and chemotype of the strains isolated.

Analysis of molecular variance (AMOVA) indicated a high genetic variability within rather than between F. graminearum populations.

The finding of F. cerealis in durum wheat grains indicates the need for investigating if this fungus is the responsible for the NIV contamination found in wheat in Argentina. © 2017 Koninklijke Nederlandse Planteziektenkundige Vereniging INPR info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/2.5/ar http://hdl.handle.net/20.500.12110/paper_09291873_v_n_p1_Palacios
