Interpretive Summary:

Technical Abstract: Fusarium head blight is a potentially devastating disease that reduces yield, quality and economic value of wheat and barley. The quantitative nature of resistance and tremendous expense of phenotypic screening indicate that the search for resistance might be expedited by molecular markers. At present, several groups are pursuing this route independently of one another. One concern is that the research carried out by individual labs, while adding to genetic map information, will not necessarily yield breeder-friendly tools that can be used to select for resistance. A second issue is that markers' relevance across populations is not being addressed by the current approach. Prospects for a more systematic, centralized approach to molecular marker identification and deployment will be considered. Several models including regional labs and public/private partnerships will be discussed.
