ARS researchers are screening the National Small Grains Collections for genes that could give U.S. wheats and barleys resistance to Ug99, a new stem rust that overcomes all previous stem rust resistance.
Repair of critical deferred maintenance including replacing deteriorated roofing systems on Buildings 102 and 103.

Research at the Small Grains and Potato Germplasm Research Unit
The Small Grains and Potato Germplasm Research Unit safeguards the genebank collection of wheat, barley, oats, and other cereal grains and distribute samples to thousands of researchers annually. The collection contains a valuable reservoir of seeds and genetic materials to protect our agricultural heritage and ensure the security of our Nations food supply.
For example, when Ug99, a new stem rust to which all U.S. wheat and most barley is vulnerable, ARS researchers screened the National Small Grains Collections for genes that could give U.S. wheats and barleys resistance. The sources they found are now being bred into commercial wheats and barleys to ensure that UG99 does not destroy our domestic wheat supply.
National Small Grains Collection
The National Small Grains Collection is an active germplasm collection (or genebank) that maintains collections representing global diversity of the small grains; including wheat (Triticum), barley (Hordeum), oat (Avena), rice (Oryza), rye (Secale), triticale (X Triticosecale), and various wild relatives (including Aegilops).
The National Small Grains Collection freely distributes seed to scientists worldwide. Passport and evaluation data are maintained on the Germplasm Resources Information Network
Potato Research Unit
The Potato is the number one vegetable crop in the United States, but commercial varieties are highly susceptible to a number of diseases, pests, and environmental stresses. The mission of the Potato Research Unit is to
Barley & Oat Research Unit
The Barley & Oat Research Unit's mission is generate improved strains of potato, small grains, and rainbow trout using the tools of modern science. They also maintain, evaluate, and distribute germplasm stocks from our National Small Grains Collection as well as seek to increase production efficiency in rainbow trout through the use of grain-based feeds and increased knowledge of trout physiology and nutrition.
Grain Chemistry Genetics Unit
The mission of the Grain Chemistry Genetics Unit is to develop genetic resources necessary for improving cereal nutrition quality or other end-use qualities, especially for use in human foods and animal feed . An important objective is the transfer of newly developed genetic technology to public and private groups in order to enhance the competitiveness and efficiency of agricultural production, and quality of agricultural products.
The current focus is on improving grain phytic acid, phosphorus, and mineral nutritional qualities. Humans and non-ruminant animals (poultry, swine and fish) use only a small portion of the phosphorus in cereal grainsonly that which is not found as phytic acid, the major form of phosphate in seeds. This results in waste excretion of phosphates that contribute to water pollution. So the Unit has a goal of developing new crop genetic resources with lower total phosphorus or phytic acid levels.
