Non-Technical Summary

Statement of Issues and Justification

In the last five years trends in consumer preferences, new environmental regulations, loss of crop-protection chemicals, increased input costs, new pest and disease pressures, as well as unpredictable growing conditions have increased the potato grower's risks and decreased his profits. New improved potato varieties are the most productive and cost effective manner to meet these challenging changing conditions and demands of the industry and the consumer. New varieties contain the promise of improved quality and marketability, increased yield, and increased sustainability by reducing inputs for disease and pest resistance and improved efficiency of fertility, water, management, etc. By improving sustainable production for the grower, at the same time reducing risk, increasing competitiveness, and improving environment quality the group of researchers and industry the WERA27 serves and represents is doing activities critical to providing healthy, inexpensive food supply for American consumers and our nation's food security.

The states represented by WERA27 (California, Colorado, Idaho, Montana, Oregon, Washington, Texas) produce over two-thirds of all potatoes grown in the U.S. WERA27 is composed of a regionally-diverse interdisciplinary team of breeders, geneticists, physiologists, pathologists, agronomists, biotechnologists, entomologists, virologists, extension specialists, economists, growers, and other industry representatives. This team is crucial to U.S. potato variety development and in turn, sustainability of the U.S. potato industry. Their combined participation allows for complete testing of improved germplasm that comes from federal and state breeding programs. Coordinated activities include parental identification and germplasm enhancement, controlled crosses, seedling production, selection and evaluation, initial seed increase, complete in-field and post harvest management research, advanced field and laboratory evaluations, evaluating processing quality and culinary attributes, developing agronomic recommendations for specific growing regions, and screening for resistance or susceptibility to diseases using conventional and molecular marker approaches.

Russet Burbank, the predominant variety for many decades, both for processing and fresh markets, has been steadily declining as a result of the success of varieties developed and evaluated by participants of WERA27. New varieties from this region replacing Russet Burbank production include Ranger Russet, Umatilla Russet, Rio Grande Russet, Russet Nugget, Blazer Russet, Bannock Russet, GemStar Russet, Alturas, Premier Russet and Classic Russet,with newer varieties becoming more popular due to improved performance and quality.

Chipping varieties, fresh market red-skinned and specialty varieties (e.g., pigmented flesh), and fresh market white-skinned varieties similarly has shifted away from one or two dominant varieties to that of numerous varieties, each with improved adaptation to different growing, storage or processing conditions, or market preferences. New varieties from this region include Ivory Crisp, CalWhite, Mazama, Modoc, IdaRose, Willamette, and Defender and are bringing about additional changes. Yukon Gem, a more disease resistant and better yielding yellow-fleshed variety has increased in acreage in response to increased market demand; breeders in the western region have increased emphasis on yellow-flesh and other pigmented-flesh varieties. Private European seed companies have begun to export yellow-flesh varieties, which are common in Europe, to the U.S., facilitated by Plant Variety Protection (PVP) laws that protect their intellectual property rights.

Russet Burbank requires closer management, more fertilizer, water, and pesticides than are required for varieties such as Bannock Russet, Alturas, and GemStar Russet - recent releases from the Tri-State Potato Variety Development Program. The recent movement toward sustainability, more efficient use of fertilizers and irrigation, and less dependence on agricultural pesticides, adds urgency to the need for alternative varieties better adapted to low input production.

Russet Norkotah and its later maturing, higher yielding "bull" clonal selections are a new set of varieties out of the Texas and Colorado programs which have become the predominant fresh market varieties in many areas. Russet Norkotah is early maturing with very smooth dark russet-skinned tubers that have good storage characteristics. The tubers are resistant to most physiological disorders, resulting in a high percentage of U.S. No.1 grades. The early success of these newly introduced "bull" clones has been somewhat overshadowed, however, by controversy within the industry regarding the long-term sustainability of all Russet Norkotah clones. Russet Norkotah tubers can be less palatable than many other varieties when consumed as a baked potato, especially after being held in cold storage for long periods. Also it has been found to harbor potato virus Y without displaying symptoms making it a possible hidden inoculum source for more susceptible varieties. Combinations of disease and pest resistance factors are targeting particular use of pesticides with an aim to reducing or eliminating them. For instance, Columbia root-knot (CRKN) and Corky ringspot disease (CRS) are addressed with two fumigants, Telone and Vapam, applied separately and at different times. Vapam is also used to control Verticillium wilt. With a doubly CRKN and CRS resistant potato it would be possible to control Verticillium with a green manure such as mustard. The omission of Telone and Vapam applications would save money and contribute to the pesticide reduction that MacDonalds seeks for it French fry product.

New varieties need to be tested in key production areas and compared to the traditional varieties, which is one of the key strengths of the WERA27 cooperative project. Additionally, evaluation of germplasm from a range of sources under varying conditions offers the greatest probability of identifying superior varieties with improved pest resistance and reduced production inputs. Materials that are successful in the Northwest Tri-State (Washington, Oregon, Idaho) and the new Southwest Region (Texas, Colorado, California) variety evaluation programs, as well as material from other programs, are incorporated into the WERA27 evaluation scheme. Combining promising new genetic technologies and wild germplasm with traditional breeding efforts has resulted in superior new varieties.

Health issues including phytonutrition provided by antioxidants and other compounds in potatoes are being researched under the WERA27 program. The formation of acrylamides in fried potatoes has recently caused concern in the fast food industry and today new varieties are being developed that have lower sugars and thereby reduce the formation of this questionable potato frying by-product. Storage conditions, as well as genetic make up have been examined to reduce this aspect of concern.

Sustainability issues of increasing importance include late blight disease resistance, water-use efficiency, transgenic and other biotechnology breeding tools, plant variety protection and environmental impacts are an important component of the program. Western region breeders are active in addressing these issues. It is essential that they are discussed from many perspectives and that strategies are developed as a team. It is anticipated that new varieties will provide U.S. growers the ability to meet the challenges of a constantly changing market and production conditions, thereby maintaining and potentially improving their economic well being and reducing their risks. New varieties will help maintain a healthy, inexpensive food supply for American consumers and contribute to an improved environment.

Objectives

Procedures and Activities

WERA27 annual meetings provide a unique opportunity for program participants and industry representatives to share information, compare trial results, and discuss issues that impact the region's industry. In addition to annual meetings, participants exchange thoughts and ideas through use of e-mail and the Internet. Performance information for most advanced western regional clones is routinely provided at the Central Oregon website (http://www.css.orst.edu/coarc/database.htm) and also at the Washington State University site at http://www.potatoes.wsu.edu) at the University of Idaho site at (http://www.cals.uidaho.edu/potato/) and at the Potato Variety Management Institute site at (www.pvmi.org) . The annual meetings of WERA27 allow greater efficiency in resource allocation, reduced duplication of effort, effective communication between industry and research scientists, and ideas for new research projects to address important issues and problems.

The WERA27 incorporates federal, university, and industry research elements. Breeders from the USDA/ARS and several universities conduct pre-breeding and basic breeding, incorporate improved germplasm from other ARS and state programs and provide true seed for the variety development effort. ARS workers with the ARS project at Prosser, Washington complete germplasm enhancement activities that provide pest-resistant germplasm to other western breeding projects. The Prosser researchers have also developed a breeding effort involving gourmet and colored-flesh varieties, including germplasm with increased levels of antioxidants.

Cooperation by WERA27 participants has extended beyond the original regional variety trial framework. The late blight crisis in the U.S. potato industry is being addressed by WERA27 Cooperators. All selections and varieties in the regional trial are tested for late blight resistance at Corvallis, Oregon. Common scab and rot diseases are evaluated at Aberdeen, Idaho. Viral resistance for these clones is routinely evaluated at Hermiston, Oregon and Kimberly, Idaho. Hermiston and Aberdeen sites also jointly evaluate early dying and net necrosis reactions in breeding entries. Researchers at Prosser, Washington screen regional entries for resistance to corky ringspot and Columbia root knot nematode as well. Improved resistance traits from several sources are being incorporated by USDA and state WERA27 breeders into potato germplasm. A major new coordinated effort to address the Zebra Chip Disease is now underway in several of the Western states including Texas, California, Idaho, and Washington as well as North Dakota and Nebraska. This includes research to develop varieties with tolerance/resistance to the disease and/or the insect vector. In recent years, Oregon State University has implemented marker-assisted selection (MAS) approaches to take advantage of the tools developed by basic genetics studies and translate them into applied potato breeding. New approaches to variety improvements such as gene transformation are also being utilized by university and USDA/ARS participants to produce improved varieties for testing in the regional trials.

Additional efforts come from state universities as they provide germplasm production and improvement, additional seedling production, completion of seedling selection and evaluation, initial seed increase, complete in-field and post harvest management research, advanced field and laboratory evaluations, and all aspects of commercialization. Other important activities include evaluating processing quality and culinary attributes, defining quality variables in new varieties, and developing agronomic recommendations for specific growing regions.

The industry provides large-scale evaluation, seed production beyond the initial stages, collaboration in commercialization, and additional financial support. The overall result is unparalleled cooperation and efficiency, with each institution completing the duties for which it is best equipped.

Educational Plan

Processing and fresh market industry representatives play a key role in developing, adapting and utilizing the information generated by the coordinated efforts of WERA27. Cooperative Extension specialists and agents/advisors are integral participants in WERA27. Regional trials are often located in grower cooperator fields for field day observations and programs. This type of continued industry participation in WERA27 is indispensable to the success of the program.

Annual meetings are held on a rotating basis in Washington, Oregon, Idaho or Colorado in conjunction with each state grower conferences, and the NW Tri-State and the SW Regional groups' annual meeting. Summaries of all regional trials are distributed and discussed. This allows and encourages dialogue among scientists, growers, extension and industry personnel.
