Research Projects: Virulence and race dynamics of wheat leaf rust (Puccinia triticina) in the United States Virulence and molecular (microsatellite-simple sequence repeat unit) characterization of U.S. and world-wide populations of Puccinia triticina Characterization of Puccinia triticina isolates with different telial hosts Genetics of leaf rust resistance in U.S. spring and winter wheat cultivars Mapping of leaf rust resistance genes derived from wheat cultivars with durable resistance Development of isogenic wheat lines with leaf rust resistance genes Postulation of leaf rust resistance genes in U.S. wheat cultivars and advanced germplasm lines
