Researchers at the Cereal Disease Laboratory test small grain cultivars and experimental lines to determine their resistance to leaf and stem rust.  In seedling tests in the greenhouse, we inoculate cultivars and lines with selected leaf and stem rust races in an effort to determine the presence of rust resistance genes. In adult field tests, we artificially inoculate nurseries with rust and then rate cultivars and lines on their rust resistance.
