U.S. Agriculture Secretary
Mike Johanns today announced that a consortium of public wheat
breeders and scientists at 18 universities led by the University
of California, Davis will be awarded more than $5 million to
advance technology to rapidly identify genes that may produce
higher quality, disease-resistant wheat.
"This research will help U.S.
wheat breeders to improve wheat yield, develop drought resistant
wheat and help the environment," said Johanns. "We are proud to
advance President Bush's goal to help keep America competitive
by supporting innovation that will improve our quality of life
and strengthen our economy."
Useful quality and production
traits on the wheat genome will be marked with a new technology
called Marker Assisted Selection. The genomic traits, once
marked, are called molecular markers and are landmarks in the
chromosome maps that help plant scientists identify specific
chromosome segments. Breeders use these markers to increase
their precision in selecting the best trait combinations for
specific varieties. For example, a plant scientist might mark a
combination of genes known to increase resistance to drought.
Breeders, who want that quality in their wheat, use that
information to know which gene combinations to insert into their
wheat line.
Researchers will work with USDA
genotyping laboratories to provide analyses of thousands of
molecular markers needed to insert the targeted genes into
breeding lines. The genetic information will be stored in
national databases and seed stocks deposited in USDA's Small
Grain Collection, providing long-term public access of genetic
information and resources for wheat breeders and researchers
nationwide.
The project includes an
extensive outreach component to share information about these
new technologies with the public and an educational program to
attract new students to agriculture and train them in modern and
traditional breeding techniques.
USDA's Cooperative State
Research, Education, and Extension Service (CSREES) administered
the award through the National Research Initiative (NRI). It
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
