Technical Abstract: During the 18th Biennial Meeting of the Bean Improvement Cooperative (October 31 to November 2, 2005), a special workshop (4th International Rust Workshop) was convened to provide an overview on common bean vulnerability to and advances in management of common rust (caused by Uromyces appendiculatus) and Asian soybean rust (caused by Phakopsora pachyrhizi). A number of critical issues, needs and challenges emerged that have been compiled for use in strategic planning for and prioritization by the research community and the bean industry. Selected general issues for rusts of common bean: 1. Develop universal protocols for collection, preservation, inoculation and description of pathogenic responses and expression of genetic variability; 2. Expand knowledge of pathogen biology, epidemiology, and especially the role of the sexual stage; 3. Expand use of molecular markers for pathogen resistance in germplasm improvement and varietal release efforts. Selected specific issues for Asian soybean rust of common bean: 1. Identify and characterize genetic resistance from cultivated and wild plant sources; 2. Expand the scope of germplasm rust resistance evaluation of Phaseolus vulgaris, other Phaseolus and legume species; 3. Identify and expand funding resources to emphasize research at the national and international level with this pathogen and its hosts; 4. Search for resistance genes in P. vulgaris for transfer to Glycine max. Selected specific issues for common rust of common bean: 1. Develop molecular markers to facilitate elucidation of coevolution of the common rust pathogen and its bean host and expand knowledge base on the common bean – common rust model; 2. Preserve and expand the historical and working collection of pathogen isolates at the USDA/ARS Beltsville facility, and duplicate other collections as projects terminate and active rust personnel retire; 3. Identify and expand funding resources to emphasize research at the national and international levels with this pathogen and its hosts.
