Wheat rusts present an ever-changing global threat to the worlds wheat crop. Emergence of virulent new races in one region has implications for other regions, due to wind-borne or human-borne movements. Therefore informed decision making regarding control and mitigation of wheat rusts requires an integrated set of datasets on both pathogen and host at the global scale. The Global Cereal Rust Monitoring System (GCRMS), created under the Durable Rust resistance in Wheat (DRRW) project, represents a unique and increasingly comprehensive resource of rust information. A suite of tools are now available giving access to an unprecedented set of data for rust surveys, alternate hosts (barberry), rust pathotypes, trap nurseries and resistant cultivars. Standardized protocols for data collection have permitted the development of a comprehensive data management system, named the Wheat Rust Toolbox. Integration of the CIMMYT Wheat Atlas and the Genetic Resources Information System (GRIS) databases provides a rich resource on wheat cultivars and their resistance to important rust races. Data access is facilitated via dedicated web portals such as Rust Tracker (www.rusttracker.org) and the Global Rust Reference Center (www.wheatrust.org)Current status and new developments relating to the Global Cereal Rust Monitoring System and related information resources are described.
