AFLP markers linked to Fusarium head blight resistance in Triticum aestivum.
… used to find markers linked 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 …

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 …

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 …

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 …

Simultaneous Mapping and Pyramiding of Fusarium Head Blight Resistance Loci in Wheat Breeding Populations
<p>QTL linkage analysis for plants has relied on large single-cross mapping populations derived from phenotypically divergent parent lines. This approach creates a disjunction between QTL mapping and marker-assisted breeding efforts aimed at pyramiding QTL, since no direct bridge exists between the …

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 …

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 …

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 …

Chitosan oligosaccharide: use to control Fusarium head blight and to reduce deoxynivalenol accumulation in wheat grains
… diseases can affect crop yield. Among them, Fusarium head blight (FHB), caused by members of the Fusarium graminearum species complex, is one of the most serious wheat diseases worldwide, resulting in lost ofin yield and grain quality due to the accumulation of mycotoxins. There are several …

Effects of chitosan oligosaccharide-amended fungicide treatments on the control of fusarium head blight in wheat
Fusarium Head Blight (FHB) is a destructive fungal disease of wheat caused primarily by Fusarium gramineraum, which reduces grain yield and quality through the accumulation of mycotoxins, especially deoxynivalenol (DON). Current management strategies rely heavily on fungicide applications; however, …

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 …

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 …
-
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 …

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 …

The wheat seed phytomicrobiome as a potential source of resistance to the fungal disease, Fusarium head blight
… plant pathogens. We investigated the wheat seed-head microbiome (phytomicrobiome) as a potential source of resistance to Fusarium head blight (FHB), or scab. FHB is a devastating disease in wheat, and other cereal grains, that causes losses in both quantity, through reduced yield, and quality of …

WAVELENGTH AND VISUAL FEATURE SELECTION FOR NON-DESTRUCTIVE EVALUATION OF FUSARIUM HEAD BLIGHT IN WHEAT USING HYPERSPECTRAL IMAGING
Fusarium head blight (FHB) is a fungal disease affecting the heads of cereal crops and has caused significant economic losses in the Canadian prairie wheat industry. Although wheat breeding efforts to enhance resistance genes are ongoing, efficient and accurate detection of FHB remains critical for …
-
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 …

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 …

Effects of Rain and Simulated Rain on Deoxynivalenol Levels in Grain and Chaff of Winter Wheat with Fusarium Head Blight
<p>Wheat grain affected by Fusarium head blight (FHB) contains the mycotoxin deoxynivalenol (DON) that is harmful to humans and animals. Reducing the amount of DON in grain is the goal of management practices for FHB so it is important to understand the factors affecting DON in grain. Some studies …
