Combining and mapping QTL for fusarium head blight (FHB) resistance in wheat
<p>Fusarium head blight (FHB) has become one of the most damaging wheat diseases in humid and semi-humid regions around the world. Single gene resistance to FHB in wheat provides only partial resistance and also the disease severity is highly influenced by environment. Consequently multiple genes …

Identification of Native FHB Resistance QTL in the SRW Wheat Cultivar Jamestown
Fusarium Head Blight (FHB) is a devastating fungal disease of wheat (Triticum aestivum L.) and results in significant economic losses due to reductions in grain yield and the accumulation of mycotoxins, such as deoxynivalenol (DON) and nivalenol (NIV). As a result, breeding programs have been …

Assessment and Reaction of Triticum aestivum Genotypes to Fusarium graminearum and effects on Traits Related to Grain Yield and Seed Quality
… causal organism of fusarium head blight (FHB), has become a major pathogen of wheat (Triticum aestivum L.) throughout North America. Since its discovery in the United States, the disease has spread south and east until at present it is an annual threat for growers of winter wheat in the …

Molecular mapping of quantitative trait loci (QTL) for Fusarium head blight (FHB) resistance and agronomic traits in US hard winter wheat
Fusarium head blight (FHB) is one of the devastating fungal diseases in wheat and results in dramatic losses in grain yield and quality. Use of genetic resistance is an effective approach to FHB control, but highly FHB resistant germplasms usually have many undesirable agronomic traits. To dissect …

AFLP markers linked to Fusarium head blight resistance in Triticum aestivum.
… to genes controlling Fusarium head blight (FHB) resistance in Triticum aestivum L. FHB is a disease of cereal crops that results in reduced wheat yields, discoloured, shrivelled kernels, mycotoxin accumulation, and reduced seed and grain quality. Since resistance mechanisms in wheat are …

Quantitative Trait Loci for Resistance to Fusarium Head Blight in the Hulless Winter Barley Cultivar Eve
Fusarium head blight (FHB), caused by Fusarium graminearum Schwabe, is a devastating fungal disease that affects barley production worldwide through damaged kernels, low yields, and production of mycotoxins. The most effective means of control is through the use of FHB resistant cultivars that are …

Control of fusarium head blight in wheat: I. Evaluation of host plant resistance and fungicides II. Molecular markers associated with QTL for resistance
Fusarium head blight (FHB) of wheat has become an increasingly important disease over the past 25 years. Significant grain and quality reductions due to FHB can be observed when there is a favorable environment for disease development. Fusarium graminearum, the primary fungal pathogen that causes …

Validation and Marker-Assisted Selection of Two Major Quantitative Trait Loci Conditioning Fusarium Head Blight Resistance in Wheat
Fusarium head blight (FHB) is one of the most destructive diseases of common wheat (Triticum eastivum L.) worldwide. Resistance to FHB is an ideal trait for which molecular marker assisted selection (MAS) would facilitate breeding and cultivar development efforts. Validation of quantitative trait …

Development of new tools and germplasms for improvement of wheat resistance to Fusarium head blight
Wheat Fusarium head blight (FHB) is a devastating disease of wheat worldwide, which can significantly reduce grain yield and quality. Although the application of fungicides can reduce FHB damage, growing FHB resistant wheat is the most effective and eco-friendly approach to reduce the losses. To …

A Genome Wide Association Study for Fusarium Head Blight Resistance in Southern Soft Red Winter Wheat
<p>Fusarium head blight (FHB) is a disease of small grains caused by the fungal pathogen Fusarium graminearum. FHB poses potential economic losses and health risks due to the accumulation of the mycotoxin deoxynivalenol (DON) on infected seed heads. The objectives of this study are: 1) evaluate …

Avoiding trade-off when enhancing Fusarium head blight resistance of barley
Fusarium head blight (FHB) is an economically important disease of barley caused by mycotoxin-producing Fusarium species. Resistance to FHB is associated with several agronomic traits, particularly height. Taller cultivars are generally more resistant; however increased height is less favourable …

Evaluation of an inoculation method and quantitative trait loci for fusarium head blight resistance in wheat
Fusarium head blight (FHB), which is principally caused in the U.S. by Fusarium graminearum Schwabe [telemorph: Gibberella zeae Schw. (Petch)], is a devastating disease of wheat (Triticum aestivum L.) and barley (Horderum vulgare L.). Losses inflicted by this disease are the result of reductions in …

Genomic selection and quantitative trait loci mapping for Fusarium head blight resistance in wheat (Triticum aestivum L.)
Fusarium head blight (FHB) is a destructive disease of wheat (Triticum aestivum L.) occurring in most growing areas. The disease is primarily caused by Fusarium graminearum Schwabe [telemorph: Gibberella zeae Schw. (Petch)], in North America, and the majority of current wheat cultivars are …

Utilization of tall wheatgrass translocation lines to improve fusarium head blight resistance in wheat
<p>Fusarium head blight (FHB) and leaf rust (LR) are two major fungal pathogens threatening the wheat crop, consequently identifying resistance genes from various sources is always of importance to wheat breeders. Type II FHB resistance in wheat has been improved by introgressing QTL from landraces …

EVALUATION OF SCAB RESISTANCE QUANTITATIVE TRAIT LOCI (QTL) EFFECTS ON WHEAT
Fusarium Head Blight (FHB) of wheat (<italic>Triticum aestivum</italic>), caused by <italic>Fusarium graminearum</italic>, is a disease that periodically strikes the mid-Atlantic region of the USA. Breeding for resistant wheat cultivar is an effective method of disease control. McCormick, a …

Background-dependent genetic architecture of Fusarium head blight resistance in U.S. hard winter wheat
Fusarium head blight (FHB), caused primarily by Fusarium graminearum, is one of the most destructive diseases of wheat worldwide, causing substantial yield losses and mycotoxin contamination of grain. Deployment of major resistance quantitative trait loci (QTL) through marker-assisted breeding is …

The Contribution of Within-Field Inoculum Sources of Gibberella zeae to Fusarium Head Blight in Winter Wheat and Barley
Fusarium head blight (FHB) is one of the most economically important diseases of small grains and continues to impact crops when environmental conditions are favorable to Gibberella zeae (Fusarium graminearum), the causal agent of the disease. Corn residues are considered to be primary sources of …

Detection of Fusarium Head Blight on Wheat Spikelets Using a Multi-Scale Feature Fusion CNN Model
Fusarium head blight (FHB) is a globally significant fungal disease that severely impacts wheat crops, leading to reduced yields, degraded grain quality, and the accumulation of harmful mycotoxins. These mycotoxins pose severe threats to human and animal health and result in substantial economic …

Brachypodium distachyon as a genetic model pathosystem to study resistance against fungal pathogens of small grain cereals
ABSTRACT Fusarium head blight (FHB) and other Fusarium diseases of wheat and other small-grain cereals cause yield reduction and grain contamination with harmful mycotoxins, mainly deoxynivalenol (DON). Little is known about the mechanistic basis of resistance to Fusarium in cereals due to the …
