The quality data as well as agronomic data are also available at Grain Genes
under their quality testing section. The end use quality data are presented here, classified by crop year.
USDA-ARS Western Wheat Quality Lab.
Dr. Craig F. Morris, Director;
Doug Engle, Cultivar Development
The USDA Agricultural Research Service's Western Wheat Quality Laboratory (WWQL) located on the Washington
campus in Pullman, Washington, provides a
detailed and thorough assessment of the end-use quality of experimental
lines from wheat breeding programs in the Western States.
The Western Regional Nurseries (WRN) are a cooperative
endeavor of public and private wheat breeders who evaluate each
other's breeding lines, as a group, over multiple locations.
Dr. Kim Campbell
, ARS Research
Geneticist, is the Coordinator of the WRN system. Breeding lines
are grown in one of three nurseries, the Western Regional Hard
Winter Wheat Nursery, the Western Regional Soft Winter Wheat Nursery,
and the Western Regional Spring Wheat Nursery. For end-use quality
assessment, the spring wheat entries are divided into a Western
Regional Hard Spring Wheat Nursery and a Western Regional Soft
Spring Wheat Nursery.
The data and comments which appear here are also
included in the report, Results From Cooperative Wheat Varietal
Experiments in the Western Region. This report also contains
a listing of cooperating agencies and personnel, nursery locations,
plot management, test site information and agronomic and pathological
Grain of nursery entries is submitted by the cooperators
directly to the WWQL. We make a preliminary assessment of general
grain quality by measuring the test weight, protein and hardness,
and visually inspecting the grain for sprout damage and other
defects on 2-3 check varieties. Based on this preliminary assessment,
appropriate locations are selected and equal quantities of grain
from two or more locations is composited to create the test sample.
