Agriculture Secretary Mike Johanns today announced
USDA is awarding $5 million to
a consortium of scientists at 19 institutions led by the
University of Minnesota to identify genes that produce higher
yielding, higher quality, disease-resistant barley.
"This research will help our
producers increase their competitiveness by producing high
yielding, high quality barley," said Johanns. "The knowledge
acquired by this research will be provided to scientists,
growers and industry breeders, continuing USDA's long history in
promoting agriculture research."
The goal is to develop and use
the tools of genomics to develop new barley cultivars.
Scientists will develop a detailed genetic "road map" of barley
and proceed to identify genes linked to important traits with
molecular markers in 10 breeding programs across the country.
Molecular markers are landmarks in the chromosome maps that help
plant scientists identify specific chromosome segments.
Researchers will use the
science of association genetics to identify genes controlling
yield, food and malt quality, and disease resistance.
Association genetics deals with evaluating and measuring the
degree of association between the molecular markers (genes) and
the traits of interest.
Marker-assisted selection
technology allows breeders to more precisely select the best
trait combinations for specific varieties. For example, a plant
scientist might mark a combination of genes known to increase
disease resistance. Breeders wanting the disease resistance
trait use marker information to identify lines containing that
specific combination of genes.
In addition, education and
outreach will be integral component of the project. Students
will be included in all aspects of the projects to ensure the
next generation of plant breeders is educated. Data and results
will be available to scientists, growers and industry through
the project's public Web site at

USDA's Cooperative State
Research, Education, and Extension Service (CSREES) administered
the award through the National Research Initiative (NRI). The
NRI supports research, education and extension grants that
address key problems of national, regional and multi-state
importance in sustaining all components of agriculture.
CSREES advances knowledge for
agriculture, the environment, human health and well-being, and
communities by supporting research, education, and extension
programs in the Land-Grant University System and other partner
organizations. For more information, visit
