The link to CIMMYT (International Wheat and Maize Improvement Center) has been on going over a long period of time. The University of Sydney has had a number of graduates employed by CIMMYT, most notable being: Dr Sanjaya Rajaram, Prof Richard Trethowan and Dr Ravi Singh. This has lead to close linkages between the groups, one good example being in 2005 based on funding from the Australian Centre for International Agricultural Research (ACIAR) for a project with CIMMYT, PBI and ICARDA to improve the early identification and control of yellow rust of wheat in Asia.

The collaboration with PBI has been long term with International Cereal Nurseries produced at CIMMYT being sent to Australia for evaluations against the cereal rust diseases and the information is processed back to CIMMYT. This has assisted CIMMYT in their mission to increase productivity of wheat to ensure global food security and reduce poverty.
