DEVELOPMENT OF SCAB RESISTANT SOFT RED WINTER WHEAT VARIETIES AND SCAB RESISTANCE QTL MAPPING

Project Title 1 - Development of Scab Resistant Soft Red Winter Wheat Varieties and Scab Resistance QTL Mapping: Development of high-yielding, well-adapted Fusarium head blight (FHB) resistant varieties is an essential component in reducing substantial economic losses due to FHB. This research addresses the following research priorities of the USWBSI Action Plan: development and release of varieties with improved FHB resistance, introgression of FHB resistance into breeding germplasm, and development and mapping of markers for sources of FHB resistance. Project Title 2 - Fungicide x Variety Interaction Experiment: The objective of this experiment is to examine the effectiveness of genetic resistance and fungicide application singly and in combination in reducing FHB symptoms, FDK and DON under heavy disease pressure. Project Title 3 - Mapping FHB QTL in an IL97-1828 x Clark Derived RIL Population: Our objective in this research project is to identify molecular markers associated with loci for FHB resistance in a source that does not trace back to a Chinese source of FHB resistance (so called ¿native¿ resistance).
