Participants
The joint general meeting was held Wednesday, June 27, and began with a welcome from Dr. Robert Zemetra, Chair of the Dept. of PSES, University of Idaho, followed by State reports, an update from Marty Draper, CSREES on the IPM-PIPE program and tracking cereal rusts, and short reports on special topics in the afternoon. State reports were presented for Arkansas, California, Idaho, Illinois, Kansas, Minnesota, Montana, Nebraska, New York, North Dakota, Ohio, Oregon, South Dakota, and Washington. In addition, reports on small grain diseases in Alberta, Canada and Queensland, Australia, were given by Denis Gaudet and Mark Sutherland, respectively. Reports on special topics in the afternoon included Leaf and Stem Rust by Jim Kolmer, Stripe Rust by Xianming Chen, Fusarium Head Blight by Ruth Dill-Macky, Aster Yellows by Char Hollingsworth, Nematodes by Dick Smiley, Crown Rot by Mark Sutherland, and Microarray Analysis of a Putative Tyrosine Phosphatase by Jill Petrisko. A social and dinner was held at the Red Lion Inn in the evening.
A field tour of USDA-ARS and University of Idaho research programs at the University of Idaho Aberdeen Research and Extension Center was held on Thursday, June 28. Mike Bonman provided and overview of USDA programs including the small grain collection housed in Aberdeen and Juliet Windes described research on Fusarium crown rot and wheat breeding conducted by University of Idaho scientists. Field stops and discussion included Rust Screening by Eric Jackson and Maricelis Acevedo, National Small Grains Collection by Harold Bockelman, Wheat Breeding by Jianli Chen, Extension Variety and Pathology Trials by Juliet Windes, and Cereal Smuts by Blair Goates. The meeting ended with a social and dinner at the home of Juliet Windes.
Accomplishments
Revision of the List of Common Names of Wheat Diseases is largely complete and is ready for distribution to the editors prior to submission. This collaborative effort between NCERA-184 and WERA-97 is a significant accomplishment since it has been 18 years since the last edition was published.
WERA-97 participants decided to meet jointly with the Western Wheat Workers at UC Davis in 2008. This joint meeting continues a long tradition of cooperative interaction with the Western Wheat Workers, which is composed largely of breeders and production system scientists. Maintaining communication among small grain scientists in different geographic regions of the country and disciplines is considered critical for cooperative research, as well as among established individuals and those in the early stages of their careers.
Participants considered the joint WERA-97/NCERA-184 meetings in 2006 and 2007 to be a success and discussed opportunities for future joint meetings, perhaps in 2010. The broad representation present at this meeting resulted in discussion of establishing a national committee for small grain diseases to enhance communication among those working in this area.
WERA-97 continues to fulfill the objectives of communicating and coordinating research activities among its members, which is largely composed of public sector scientists but also includes regular participation by members of the private sector. Discussions at this annual meeting help inform its participants of potential new problems, and new approaches to the control of long-established problems.
Impacts
- Participants were updated on the situation with UG99, a new and potentially damaging race of wheat stem rust detected in Uganda, Kenya and Ethiopia that has virulence on the wheat stem rust resistance gene Sr31, which is present in many CIMMYT varieties. This information will be important to pathologists and wheat breeders involved in developing wheat varieties with resistance to stem rust and enabling them to respond proactively since this race is not present in the US.
- Revision of the Compendium of Wheat Diseases represents a major revision that will be useful to growers, extension and research personnel in the U.S. and elsewhere in the world where wheat is grown.
- Research to identify the race structure of wheat and barley stripe rust pathogens across the U.S. is continuing and the information is made available to the public, including wheat and barley breeders, so they can use appropriate disease resistance genes for their respective regions to minimize losses to this disease.
- Pathologists from three states where hard red winter wheat is produced have recently begun a tri-state Fusarium head blight nursery so that advanced breeding lines may be tested at multiple sites in the region. Such data are valuable to help understand the effective range and durability of deployed resistance genes.
