Quantitative 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...
متن کاملValidation, Saturation, and Marker-Assisted Selection of Quantitative Trait Loci Conferring Adult Plant Resistance to Powdery
Powdery mildew caused by Blumeria graminis f. sp. tritici is one of the most devastating diseases in wheat (Triticum aestivum) worldwide. Hypersensitive, race specific genes primarily have been deployed to control the disease, however recent efforts have shifted to breeding for more durable resistance, such as ‘adult plant resistance’ (APR). Molecular markers and quantitative trait loci (QTL) a...
متن کاملQuantitative trait loci in Two Soybean Recombinant Inbred Line Populations Segregating for Yield and Disease Resistance.
Molecular makers linked to quantitative trait loci (QTL) can assist soybean [Glycine max (L.) Merr.] breeders to combine traits of low heritability, such as yield, with disease resistance. The objective of this study was to identify markers linked to yield QTL in two recombinant inbred line (RIL) populations ['Essex' x 'Forrest' (ExF; n = 100) and 'Flyer' x 'Hartwig' (FxH; n = 94)] that also se...
متن کاملIdentification and Molecular Mapping of a Gene in Wheat Conferring Resistance to Mycosphaerella graminicola.
ABSTRACT Septoria tritici leaf blotch (STB), caused by the ascomycete Mycosphaerella graminicola (anamorph Septoria tritici), is an economically important disease of wheat. Breeding for resistance to STB is the most effective means to control this disease and can be facilitated through the use of molecular markers. However, molecular markers linked to most genes for resistance to STB are not ye...
متن کاملPartial Resistance to Septoria Tritici Blotch (Mycosphaerella graminicola) in Wheat Cultivars Arina and Riband.
ABSTRACT Partial resistance to Septoria tritici blotch (STB) and its inheritance were investigated in a doubled-haploid population of a cross between cvs. Arina and Riband. The former has good partial resistance whereas the latter is susceptible. In adult plant trials in polytunnels, STB disease scores were negatively correlated with heading date. Resistance was not specific to any of the three...
