Non-Technical Summary

Statement of Issues and Justification

Wheat quality is defined by its diverse end-uses. Wheat's unique and varied processing attributes, as well as tradition, produced many market classes based on end-use quality and specialized industries capture value from those classes. Many scientific disciplines, both public and private, seek to improve the quality components of all market classes of wheat. The farming community, milling and baking industries, and the entire wheat industry recognize the need to coordinate quality improvement efforts. This project will be a multi-disciplinary committee for exchange of wheat quality information among growers, researchers and industry. Its primary goal is to use industry input to focus public research efforts and educate growers, researchers and industry about the wheat cultivars, newest wheat quality research tools, and wheat food product specifications.

Objectives

Procedures and Activities

1. Coordinate improvement in wheat quality in of all classes of PNW wheat for both domestic and export end-uses.

Target values and accepted quality ranges for the classes of wheat grown in the PNW will be established and refined

Large-scale test information from domestic and industry partners will be discussed by the group and shared so that the USDA/ARS Wheat Quality Lab and the Wheat Marketing Center can translate these needs and information to small-scale tests

Small-scale tests will be used, as possible, by wheat breeders in cultivar improvement efforts

Breeding and extension testing will be coordinated to aid in identification of environments conducive to high quality wheat production for specific market classes

Superior germplasm and optimal production areas will be identified to meet market needs and opportunities

2. Facilitate information exchange among research, extension, and industry representatives on wheat end use quality needs.

The WERA081 annual meeting will be structured to allow for maximum information exchange among university and industry partners.

WERA081, Pacific Northwest Wheat Quality Council and Asian Product Collaborative meetings will be held together toward this end

A web site will be established in association with the USDA/ARS Western Wheat Quality Lab to facilitate information exchange in the interval between meetings.

3. Evaluate grain quality in regional and extension nurseries and improve quality evaluations of those trials.

A standard set of lines will be grown across a wide range of regional environments by project cooperators. These trials will include both breeder nurseries and extension trials  both small-plot and drill strip. The goal is to produce large amounts of seed to allow intensive quality testing

Grain samples from regional trials will be analyzed by the USDA/ARS Wheat Quality Lab. This information will be widely shared to allow breeders to assess how widely adapted his/her lines are with respect to quality

Regional quality information will also inform industry partners as to which cultivars have promise for their purchasing area.

4. Use regional nursery and extension testing data to measure genotype and environment effects on end use quality and in turn improve PNW wheat marketing.

Data from regional trials (extension and breeder) will be used to determine the influence of genotype, environment, and their interaction on end-use quality

Individual state and ARS laboratories will conduct small sample evaluation for protein quality (SDS sedimentation or SRC lactic acid), color (using PPO tests or Minolta values on noodle sheets), test weight and kernel hardness, etc. This information can be shared at either the annual meeting or on the Web.

5. Utilize advanced instrumentation, molecular biology, and biochemistry to improve end-use quality of adapted cultivars.

WERA081 partners will identify new methods for assessing and selecting quality and link these methods to measures of value by end-users

University researchers will attempt to identify molecular markers that can be related to quality traits that can only otherwise be determined by extensive testing and baking. Utility of these tests will be assessed in cooperation with industry partners

Work will continue to identify and refine the capability of instrumentation such as TxTA2 texture analyzer and the Rapid Viscoanalyzer for measurement of starch pasting that can be used for rapid, real-time testing of wheat quality

Expected Outcomes and Impacts

Projected Participation

View Appendix E: Participation

Educational Plan

Annual meetings will provide a major opportunity for educational outreach and exchange between industry and research. The WERA081 will meet in conjunction with the Pacific Northwest Wheat Quality Council and the Pacific Northwest Division of the AACC. The Pacific Northwest Wheat Quality Council is an industry centered group that meets to discuss quality issues and collaborates on cultivar testing. Interaction with this group has proved to be enlightening and invaluable. Researchers throughout the Western Region now have access to industry-developed techniques such as the solvent retention capacity test through industry collaboration in WERA081 and PNW Wheat Quality Council. Along with researchers, extension educators, and industry, the participation by growers and their representatives at the state wheat commissions at the annual meeting either by individual farmers or their representatives on the state wheat commissions. This input by growers to the committee is encouraged to improve farmer understanding end products and markets available for their crops and how their cultural practices and varietal choices impact these products.

Researchers communicate the information gathered at the WERA81 meeting with growers at field days, in growers meetings and through technical bulletins. More involvement by quality lab personnel in these activities should occur. Quality evaluations produced by the WERA081 and PNW Wheat Quality Council directly influence the release decisions of wheat breeders in the Western region. Similarly, quality evaluations produced by these joint councils are used by wheat commissions in promoting superior quality wheats and in discouraging production of inferior quality wheats.

Organization/Governance

Elected officers consist of a chair, chair-elect and secretary. Officers are elected at each annual meeting.
