Cultivar Name Clearance. Breeders in the United States are encouraged to have proposed names for new cultivars checked for duplication, trademark, and other possible infringements. The National Small Grains Collection will be glad to assist you. Send the proposed name to: Harold E. Bockelman, USDA-ARS-NSGC, P.O. Box 307, Aberdeen, ID 83210, Fax 208-397-4165, nsgchb@ars-grin.gov. If desired, more than one name may be submitted, listed in order of preference. This will save considerable time if a conflict is found with the first name. Available records (GRIN, CI/PI cards, variety files, etc.) here at Aberdeen are checked for conflicts with the proposed name. If a conflict is found (previous use of the name for that crop), the breeder is requested to submit a different name. If no conflicts are found, the requested name is forwarded to the Agricultural Marketing Service where the proposed name is checked for possible conflicts in trademarks, etc. The Agricultural Marketing Service does not guarantee that its findings are the final word since their files may not be complete and/or there may be unregistered trademarks. This clearance procedure generally requires about four weeks.

Elite Germplasm Requested. Breeders are encouraged to consider submitting their elite lines for inclusion in the National Small Grains Collection (NSGC). Of special interest are lines that have been in uniform nurseries, but are not to be released as cultivars. Historically, uniform nurseries been the testing-grounds for the most advanced, elite germplasm from the various public and private breeding programs. Entries in uniform nurseries and other breeding materials that are never released as cultivars are still of potential value to breeders, pathologists, entomologists, and other researchers. Breeders should submit 200-500 g of untreated seed to the NSGC (address: P.O. Box 307, Aberdeen, ID 83210). Seed from outside of the United States should be sent to the USDA Plant Germplasm Quarantine Center (address: Bldg. 580, BARC-East, Beltsville, MD 20705) with enclosed forwarding directions. Provide a description of the germplasm, including: donor (breeder, institution); botanical and common name; cultivar name and/or other identifiers (breeder line or selection number, etc.); pedigree; descriptive information (of important traits and special characteristics); and growth habit. Assignment of a PI number and inclusion in the NSGC makes the germplasm available for research purposes to bona fide scientists in the U.S. and worldwide. Please note that a different procedure applies if you are obtaining Crop Science registration. Follow directions provided by the crop registration committee.

Guidelines for Exporting Seed. All seed sent to a foreign country should be inspected and receive a phytosanitary certificate. In most cases a fee payable to APHIS (Animal & Plant Health Inspection Service) is required to cover the cost of the pc. You may wish to work with APHIS personnel in your state or your State Department of Agriculture to obtain a phytosanitary certificate. Also, please be aware of any import permits and additional declarations that certain importing countries may require to accompany the shipment.

Guidelines for Importing Seed. Any scientist importing seed should be aware of any restrictions that apply. USDA-APHIS personnel can provide current information on applicable restrictions.

The systematic evaluation of barley accessions in the USDA-ARS National Small Grains Collection (NSGC) and other elite germplasm continued to be coordinated by National Small Grains Germplasm Research Facility (NSGGRF) staff at Aberdeen during 1997. Cooperative barley evaluations continued for reaction to Russian wheat aphid; barley stripe rust; spot and net blotch of barley; and barley stripe mosaic virus as well as evaluations of beta-glucan, protein, and oil content of NSGC barley accessions. The staff also contributes as opportunities arise to cooperative efforts concerned with Fusarium head blight research. Evaluation of NSGC small grains germplasm, including especially various spike descriptors, continued at Maricopa, Arizona in 1997 under the supervision of S. Nieto; however, germplasm maintenance operations have been curtailed at Maricopa since Karnal bunt was identified in Arizona in March 1996. Specific Cooperative Agreements or within ARS Fund Transfers involving cooperative evaluations and related research for all small grains involve several University and ARS projects in several states.

Data obtained from evaluations of NSGC germplasm are entered in the Germplasm Resources Information Network (GRIN) system by the NSGGRF staff in cooperation with the ARS National Germplasm Resources Laboratory, Beltsville, Maryland. Data currently available on GRIN for barley are summarized in Table 1.

An important barley germplasm evaluation effort concerned with barley stripe rust continued in 1997 in cooperation with Dr. William M. Brown, Jr., Vidal Velasco, and Dr. Joseph P. Hill, Colorado State University, Ft. Collins, Colorado under the terms of a Specific Cooperative Agreement between Colorado State University and ARS, established in 1990 and renewed in 1996 under the title "Field Evaluation of Barley Germplasm for Reaction to Barley Stripe Rust". The 1996 Barley Stripe Rust Evaluation Nursery in Cochabamba, Bolivia was composed of over 5,000 barleys, including 1,331 selections developed by ARS (Aberdeen, Idaho), Univ. of California-Davis, North Dakota State Univ., Oregon State Univ., Utah State Univ., Washington State Univ., Coors Brewing Company, Busch Agricultural Resources, Plant Breeders 1, and Western Plant Breeders (Group I); 341 National Small Grains Collection (NSGC) accessions or elite germplasm with "resistant" ratings in previous Cochabamba nurseries (Group II); and 4,168 NSGC accessions not previously evaluated (Group III). The elite series was also evaluated in Colorado, Germany, Mexico, and Texas. All field trials were conducted with endemic natural inoculum. Inoculum levels in Bolivia and Mexico were excellent while inoculum levels in Colorado and Texas were very low. In Bolivia, 58% of the cooperators selections (Group I), 93% of the elite series (Group II), and 18% of the NSGC accessions (Group III) were rated resistant.

The 1997 stripe rust evaluations did not include Bolivia, but focused on Mexico and the U.S. In addition to trials at Toluca, Mexico and the San Luis Valley of Colorado spearheaded by our colleagues at Colorado State University, the 1997 stripe rust evaluations also included cooperative trials involving Roland F. Line (ARS, Pullman, Washington); Patrick Hayes (Oregon State University, Corvallis, Oregon); and Lee F. Jackson (University of California - Davis, Davis, California). The 1997 trials at Toluca, Mexico included 265 accessions in a National Small Grains Collection Elite Series as well as 1320 entries from several cooperators grown in the Cooperative Barley Stripe Rust Trial Series. Nearly 800 entries were grown in similar stripe rust evaluation trials in the San Luis Valley of Colorado. Cooperators contributing to these trials included Rulon S. Albrechtsen/Utah State University; Michael E. Bjarko/Busch Agricultural Resources, Inc.; Tom K. Blake/Montana State University; Phil Bregitzer/ARS, Aberdeen, ID; Dale R. Clark/Western Plant Breeders; An Hang/ARS, Aberdeen, ID; Patrick M. Hayes/Oregon State University; Lee F. Jackson/ University of California-Davis; Wayne L. McProud/Plant Breeders 1; Donald C. Rasmusson/ University of Minnesota; Berry J. Treat/Coors Brewing Company; and Darrell M. Wesenberg/ARS, Aberdeen, ID. A total of 112 barley entries originating with the second author's program were evaluated in Toluca in 1997, with 57 entries rated "0", 15 rated "TR" or "TMR", and 20 entries rated "TMS". In this series the 'Morex' and 'Russell' checks were both rated 90S.

We plan to continue a cooperative Barley Stripe Rust Evaluation Nursery for the 1998 season. As in previous years, Dr. William M. Brown, Jr., Colorado State University, will direct much of this effort. Several NSGC accessions and other elite barley germplasm have been identified since 1990 with putative resistance to barley stripe rust in one or more years of testing. A number of barley varieties grown commercially in the United States are very susceptible to the new races of barley stripe rust established in the western United States. We expect to evaluate material at multiple locations, possibly including locations in the United States, Mexico, and Europe in 1998, but we will not have a nursery at Cochabamba, Bolivia in 1998.

Systematic Barley Stripe Mosaic Virus (BSMV) evaluations of NSGC barley accessions have been cooperatively conducted by ARS personnel at Aberdeen, Idaho and Fargo, North Dakota for more than 30 years. Serological tests (ELISA) for BSMV were initiated in 1987 under the supervision of Dr. Timian. Dr. Michael Edwards, USDA-ARS, North Dakota State University, Fargo, has conducted the ELISA tests since Dr. Timian's retirement. Currently, more than 16,000 NSGC accessions have been found free of BSMV. In 1997 and 1998 we are concentrating on retesting previously-tested positive accessions by testing plants in groups of five with the goal of finding sufficient BSMV-free groups to reconstitute the accession.

Cooperative evaluation of NSGC barley germplasm for beta-glucan, protein, and oil content was initiated in 1992 in cooperation with David M. Peterson and the staff of the ARS Cereal Crops Research Unit, Madison, Wisconsin. Beta-glucan and protein evaluation data have been entered in GRIN for over 7,600 barley accessions grown at Aberdeen, Idaho and nearly 1,400 accessions grown at Maricopa, Arizona. Five NSGC barley accessions lowest for beta-glucan content averaged 2.38% vs. 9.53% for the five highest accessions. Additional accessions are currently being evaluated for beta-glucan, protein, and oil content at Madison.

Evaluations similar to those described above are currently underway for other major NSGC components, including wheat, oats, rice, and triticale, at Aberdeen and a number of other locations across the United States. Important cooperative projects, especially involving barley, include the "Evaluation of Barley Germplasm for Net Blotch, Spot Blotch, and Rust Diseases" (North Dakota State University, Fargo - B.J. Steffenson) and "Field Evaluation of Barley Germplasm for Reaction to Barley Stripe Rust" (Colorado State University, Fort Collins - W.M. Brown, Jr.); and "Acquisition, Evaluation, and Conservation Strategies for Small Grains Genetic Resources" (University of California, Davis - C.O. Qualset).
