New quantitative trait loci in wheat for flag leaf resistance to Stagonospora nodorum blotch.
Stagonospora nodorum blotch (SNB) is a significant disease in some wheat-growing regions of the world. Resistance in wheat to Stagonospora nodorum is complex, whereby genes for seedling, flag leaf, and glume resistance are independent. The aims of this study were to identify alternative genes for flag leaf resistance, to compare and contrast with known quantitative trait loci (QTL) for SNB resi...
متن کاملQuantitative trait loci for seedling and adult plant resistance to Stagonospora nodorum in wheat.
Stagonospora nodorum blotch (SNB) caused by Stagonospora nodorum is a severe disease of wheat (Triticum aestivum) in many areas of the world. S. nodorum affects both seedling and adult plants causing necrosis of leaf and glume tissue, inhibiting photosynthetic capabilities, and reducing grain yield. The aims of this study were to evaluate disease response of 280 doubled haploid (DH) individuals...

Stagonospora nodorum blotch, caused by Stagonospora nodorum (Berk.) Castellani & E.G. Germano (= Septoria nodorum (Berk.) Berk. in Berk. & Broome, teleomorph: Phaeosphaeria nodorum (E. Müller) Hedjaroude) can cause serious yield and quality losses of wheat (Triticum aestivum L.) in many countries worldwide (3,14,20). Yield losses caused by this disease have been reported as high as 40% in sever...
متن کاملArtificial Inoculation of Wheat for Selecting Resistance to Stagonospora Nodorum Blotch
Phaeosphaeria nodorum (E. Muller) Hedjaroude (anamorph = Stagonospora nodorum (Berk.) Castellani & E.G. Germano) causes Stagonospora nodorum blotch (SNB), a disease of wheat (Triticum aestivum) leaves, stems, and glumes. SNB occurs persistently, but with varying degrees of severity, in the eastern U.S. soft red winter wheat region. Acceptable levels of partial resistance are available in adapte...
متن کاملQTL mapping of partial resistance in winter wheat to Stagonospora nodorum blotch.
Stagonospora nodorum blotch is an important foliar and glume disease in cereals. Inheritance of resistance in wheat appears to be quantitative. To date, breeding of partially resistant cultivars has been the only effective way to combat this pathogen. The partial resistance components, namely length of incubation period, disease severity, and length of latent period, were evaluated on a populat...
