Characterization of Resistance Sources to Fusarium Head Blight in Durum Wheat
This study assesses Fusarium head blight resistance in various Triticum turgidum subspecies, identifying dicoccum accessions with Type 2 resistance and highlighting a promising but agronomically challenging line (TRI2215) for QTL mapping, while correlating mycotoxin levels to fungal DNA via qPCR.

Detail description
The paper presents a detailed evaluation of Fusarium head blight resistance in durum wheat. Field trials and spikelet inoculations with multiple Fusarium species were paired with qPCR quantification of the TRI5 gene to measure fungal colonization. Populations of T. turgidum dicoccum showed the highest levels of Type 2 resistance—slow necrosis progression. One accession, TRI2215, combined strong resistance with suboptimal height and maturity, prompting QTL mapping efforts. The study also profiles six major Fusarium species, links deoxynivalenol accumulation to fungal DNA content, and notes phenolic compounds’ role in plant defense.
