Research Project: Impact of Environmental Variation on Genetic Expression (phenotype) of Hard Winter Wheat Quality Traits

Location: Grain Quality and Structure Research

Project Number: 3020-44000-026-00-D
Project Type: In-House Appropriated

Start Date: Jun 16, 2015
End Date: Jun 15, 2020

Objective:
Objective 1: Integration of experimental hard winter wheat germplasm, containing variability in starch and protein quality, into commercial usage across a range of production and meteorological climates. [C1; PS 1.A] Sub-objective 1A: Correlate starch and protein physiochemical changes with environmental variability for key hard winter wheat cultivars. Sub-objective 1B: Correlate the falling number test to the glucose meter for the detection of sprout damage in wheat. Objective 2: Congressionally directed mission of service, and non-hypothesis driven, the USDA-ARS Hard Winter Wheat Quality Laboratory will identify, evaluate, and screen the intrinsic end-use quality of hard winter wheat progenies in the Great Plains growing region to enhance cultivar development. [C1; PS 1.A] Sub-objective 2A: Evaluate and screen the quality attributes of hard winter wheat experimental breeding lines and improve quality of existing hard winter wheat cultivars for end-product quality of world’s wheat-based staples, such as bread (whole wheat), tortillas, and noodles and other product analyses, including enzymatic analyses to enhance intrinsic wheat quality desired by customer markets. Sub-objective 2B: Coordinate and conduct essential hard winter wheat projects of national importance, such as Wheat Quality Council (WQC), Regional Performance Nursery (RPN) and Hard Winter Wheat Crop Quality Survey (HWWCQS) for improvement of U.S wheat quality.

Approach:
Cereal grains are the foundation of nutrition worldwide with the United States being a perennial leader in hard winter wheat (HWW) production and quality. Thus, domestic and international customers come to expect high quality wheat from the Great Plains. That said, there continues to be a fierce international competition for the global HWW market. U.S. wheat breeders, researchers, quality laboratories and producers are under continuous demands to deliver quality HWW just to hold a competitive edge in both domestic and international markets. Genetic and environmental variability are critical factors that affect HWW grain composition (starch and protein) and end-product quality (pre-harvest sprouting). To meet these challenges this project is composed of a multidisciplinary team that set objectives to determine the effect of HWW protein and starch in response to critical abiotic stress events. The project plan will also include the congressionally-mandated activities of the USDA Hard Winter Wheat Quality Laboratory (HWWQL). Due to recent reductions in funding, this Congressionally mandated laboratory utilizes in excess of 83% of the resources’ dedicated to this project. The HWWQL provides critical end-use quality data to the HWW growing region, and conducts three annual evaluation projects that include the Wheat Quality Council Evaluations, Regional Performance Nursery Program, and Hard Winter Wheat Crop Quality Survey. The data from these projects assist breeders, producers, millers, bakers, and other key industry components, in making pivotal decisions regarding breeding, agronomics, processing and marketing of experimental and commercial wheat varieties, as well as vital information regarding the environmental impact on established wheat cultivars.
