Journal of Plant Registrations. 2:10-11 Interpretive Summary: Barley is an important crop to producers in the Intermountain west area of the US, and specifically Idaho. The acreage devoted to barley has remained steady, and recent increases in price should result in an increase in barley acreage in Idaho and Montana. The release of Tetonia will provide producers with a variety with improved yield potential and resistance to lodging compared to the current variety Baronesse. Tetonia was evaluated in replicated yield trials for agronomics across multiple environments and years in Idaho, Montana, Washington, and North Dakota. The data shows that it has superior yield potential compared to the current industry standard. Tetonia is expected to be adapted to both irrigated and dry land regions of Idaho and Montana.

Technical Abstract: ‘Tetonia’, a spring two-rowed feed barley (Hordeum vulgare L.) was developed by the Agricultural Research Service-USDA, Aberdeen, ID in cooperation with the University of Idaho Agriculture Experiment Station. Tetonia has performed particularly well in trials at the University of Idaho experiment station, and thus its name. In ARS and cooperative University of Idaho trials across 39 irrigated and rain fed locations throughout Idaho from 2000-06, Tetonia averaged 102 percent yield compared to Baronesse. In nine irrigated and rain-fed trials conducted by the University of Idaho extension from 2004-05 Tetonia was equal to Baronesse. Tetonia was the top performer in the 2004 WRDSBN where it averaged 111 percent of the test mean across 11 locations in Idaho, Montana, North Dakota, Utah, and Saskatoon, SK, CA. Across 56 location-years from ARS, University of Idaho, and regional trial evaluations Tetonia yielded 102 percent of Baronesse. Across 50 location-years from ARS, University of Idaho, and regional trial evaluations Tetonia and Baronesse each had test weights of 66.8 kg hL-1. Across 50 location-years Tetonia averaged 80.0 percent plump kernels compared to 84.4 percent for Baronesse. Across 43 location-years Tetonia headed 2d later than Baronesse and had a lodging rating of 1.4 compared to 1.5 for Baronesse. Across 37 location-years it was nearly identical in height to Baronesse, being on average 0.2 cm taller. In the 2004 WRDSBN disease ratings were taken for spot blotch, causal agent Cochliobolus sativus, at Saskatoon and Melfort, SK, CA. Tetonia had a rating of 7.0 and 5.0 compared to 5.0 and 5.5 for Steptoe at Saskatoon and Melfort, respectively. Net blotch, causal agent Pyrenophora teres f. teres, ratings were taken at Melfort, SK, CA, and Fargo and Langdon, ND. Again, both cultivars were similar with reactions for Tetonia being 2.0, 2.7, and 5.7, compared to 3.0, 2.4, and 4.0 for Steptoe at the three locations. In the 2005 WRDSBN reaction to net blotch and barley stripe rust, causal agent Puccinia striiformis f. sp. hordei were taken at Tammany, ID. For Tetonia, Baronesse, and Steptoe, respectively, the stripe rust the percentage diseased leaf area was 70, 60, and 80 and the net blotch rating was 5.7, 4.0, and 5.0. Tetonia is expected to be adapted to both irrigated and dry land regions of Idaho and Montana.
