- Period Covered: 06/01/2002 to 06/01/2003
- Date of Report: 09/02/2003
- Annual Meeting Dates: 06/17/2003 to 06/18/2003
Participants
The annual meeting of WCC 97 was held in Pendleton, OR June 17-18, 2003 at the Red Lion Hotel in conjunction with the annual meeting of the Western Wheat Workers. The business meeting began with updates on the Stripe Rust situation in the western U.S. by Dr. Xianming Chen, USDA-ARS Pullman, and a discussion of Root and Crown Rot complexes of wheat and barley in the Pacific Northwest by Dr. Dick Smiley, OSU-Pendleton. This was followed by state reports and separate business meetings for each group. A field trip to research plots at the OSU Columbia Basin Agricultural Research Center and the surrounding area was held on June 18. In addition to Oregon State University, plots directed by researchers from Washington State University, USDA-ARS, and private industry (AgriPro Wheat, Western Plant Breeders, and MacGregor) were observed.
State reports were given by 7 states (two in absentia). In addition, representatives of private companies provided updated information on their research directions and priorities. Overall the level of interaction among participants was excellent with discussions of several important diseases including stripe rust, Fusarium root and crown rot, common root rot, Rhizoctonia root rot, Cereal cyst nematode, Root-lesion nematode, Cephalosporium stripe, eyespot, and physiological leaf spot. There were also discussions of herbicide-resistant wheat varieties as well as prospects for GMO wheat.

Accomplishments
Meeting participants decided to meet in Pullman, WA in 2004 with the date to be determined by local host Tim Murray. WCC-97 accepted an invitation extended by Dr. Denis Gaudet to meet in Lethbridge, Canada in 2005.
This group continues to fulfill the objectives of communicating and coordinating research activities among its members. There is continued strong participation and support for its activities by members and the private sector alike.

Impacts
- Participants developed a greater understanding of the reasons for the recent epidemic of stripe rust in spring wheat in the Pacific Northwest. Methods were discussed for avoiding such epidemics in the future with breeders present at the meeting.
- Participants developed a greater understanding of crop damage caused by Fusarium crown and root rot, and of the potential for minimizing damage through selection of cultivars with acceptably high levels of tolerance.
- Participants learned that root-lesion nematode has been shown to be a yield-constraining factor in many dryland fields that have been converted from a 2-year rotation (winter wheat/summer fallow) to an annual cropping system that includes either continuous cereals or cereal/broadleaf crop rotations.
