- 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
