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 Lenetah 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. It has performed especially well under non-irrigated conditions across Idaho, but especially in north Idaho. Lenetah is not significantly better than Baronesse under irrigated conditions.

Technical Abstract: ‘Lenetah’ (reg. No. , PI ) two-rowed spring feed barley (Hordeum vulgare L.) was developed by the Agricultural Research Service, Aberdeen, ID, in cooperation with the Idaho Agricultural Experimental Station and released in December 2007. It was released due to its superior yield and test weight compared to Baronesse, the most widely grown feed barley in Idaho and Montana. The yield advantage over Baronesse is especially pronounced in north Idaho and eastern Washington. It has been evaluated and performed very well in three north Idaho counties: Lewis, Nez Perce, and Latah, and was thus named for these three counties. Lenetah is a two-rowed hulled, spring barley with a moderately lax spike which nods at maturity. The spike has smooth awns, long rachilla hairs, glume hairs that are banded, and glume awns equal in length to the glume. Laterals are sterile with a barbed apex. The kernel has white aleurone, veins with few barbs, and a crease that is open to slightly flaring. The hull is adhering, slightly wrinkled, tending to smooth. The rachis is glabrous to very few hairs. The yield performance of Lenetah has been higher than Baronesse, the most widely grown feed barley in Idaho under all conditions, but not significantly better under irrigation. Lenetah has yielded 105.9, 109.0, and 112.1 percent of Baronesse across all 31 location-years, 10 non-irrigated location-years, and 13 north Idaho location-years, respectively. Both the non-irrigated and north Idaho values are significant at P=0.01. Lenetah is similar to Baronesse for test weight and maturity, is slightly taller, and has a higher percentage plump kernels (P=.01). It has slightly higher lodging values than Baronesse, but has not experienced any significant lodging problems. Lenetah is expected to be adapted to both irrigated and dry land regions of Idaho and Montana, but especially suited to non-irrigated conditions and areas of north Idaho and eastern Washington.
