Broad-spectrum resistance loci for three quantitatively inherited diseases in two winter wheat populations

Septoria tritici blotch (STB), caused by S. tritici , Stagonospora glume blotch (SGB), caused by S. nodorum , and Fusarium head blight (FHB), caused by F. graminearum and F. culmorum , are the most important diseases of wheat ( Triticum aestivum L.) in temperate growing areas. The main goals of this...

Description
Summary:Septoria tritici blotch (STB), caused by S. tritici , Stagonospora glume blotch (SGB), caused by S. nodorum , and Fusarium head blight (FHB), caused by F. graminearum and F. culmorum , are the most important diseases of wheat ( Triticum aestivum L.) in temperate growing areas. The main goals of this study were to detect (1) new quantitative trait loci (QTL) for STB resistance in two adapted European biparental populations (Arina/Forno, History/Rubens) and (2) QTL regions for broad-spectrum resistance (BSR) to the above-mentioned diseases during the adult-plant stage in the field. The three resistances were phenotyped across 4–7 field environments and phenotypic data revealed significant ( P
