hey...thats ur ans.

Bread wheat (Triticum aestivum L. em. Thell.) is the most important cultivated crop in Canada. Fusarium head blight (FHB), caused by Fusarium graminearum Schwabe [teleomorph Gibberella zeae (Schwein) Petch] is the principal disease of wheat in North America, causing severe losses in grain yield and quality. Breeding for cultivar resistance is considered the most practical way to manage this disease. High spatiotemporal variance makes screening for disease resistance based on visual assessment of symptoms slow, difficult, and expensive. Development of a cheaper, rapid, accurate, and high throughput tool for screening resistance is the highest priority for wheat breeders. A novel method based on metabolite profiling technology was applied to discriminate resistance in wheat genotypes against FHB. The present investigation reports on three linked studies.
