Participants in CIMMYT’s 2010 Wheat Improvement and Pathology Training Program, guided by Julio Huerta (fourth from left), CIMMYT wheat pathologist, examine and take notes on the symptoms present in a set of leaf rust differentials. These are wheat lines with known responses to different leaf rust races, or pathotypes. Pathotypes vary in their virulence to different resistance genes, and so infection types and levels in different lines vary depending on the genes they contain. By codifying the responses of the differentials scientists can determine the pathotype of an unknown isolate of the pathogen.

The training course ran for three months, from 15 February to 14 May 2010, with sixteen participants from eight countries (India, Paraguay, Brazil, Ethiopia, Iran, Bangladesh, Turkey, and Afghanistan). They program was balanced between theoretical and practical learning, including wheat breeding, pathology and quality, molecular techniques, applied statistics, and participation in hands-on fieldwork such as selections, crossing, and disease screening.
