Registration of 'Tetonia' Barley

10 Journal of Plant Registrations, Vol. 2, No. 1, January 2008 ‘Tetonia’ two-rowed spring barley (Hordeum vulgare L.), (Reg. no. CV-334, PI 646199) was developed by the Agricultural Research Service, United States Department of Agriculture, and the Idaho Agricultural Experiment Station and released in January 2007. Tetonia was tested under the experimental designation 98Ab11720 and has the pedigree 85Ab2323/‘Baronesse’. The parent 85Ab2323 has the pedigree 79Ab10542/‘Crystal’ (Wesenberg et al., 1991). 79Ab10542 has the pedigree 60Ab1810-53/‘Hector’ (Wells, 1973). 60Ab1810-53 is one of 35 F11:12 lines which were composited to form the cultivar ‘Klages’ (Wesenberg et al., 1974) and has the pedigree ‘Betzes’/‘Domen’. Baronesse, a two-rowed feed barley, developed by the company Nordsaat in Germany and marketed in the U.S. by WestBred, LLC (Bozeman, MT) has the pedigree ‘Mentor’/‘Minerva’//Vada mutant/4/‘Carlsberg’/ ‘Union’//‘Opavsky’/‘Salle’/3/‘Ricardo’/5/‘Oriol’/6153P40. The spike of Tetonia is moderately lax, medium-long, and nodding. Its kernels have white aleurone and long rachilla hairs. Its hull is smooth to slightly wrinkled and it has rough awns. The cross that produced Tetonia was made in 1993 and 100 F5 spikes were selected in 1997 following pedigree selection in the F2 through F4 generations for resistance to lodging, shattering, and favorable plant and spike type under irrigation at Aberdeen, ID. These spikes were grown as progeny rows in 1998 and the row designated no. 11720 was selected because of its resistance to lodging, grain shattering, and favorable plant and spike type. Tetonia was evaluated in a non-replicated yield trial at Aberdeen, ID in 1999 and entered in replicated yield trials at Aberdeen and Tetonia, ID beginning in 2000. Tetonia entered preliminary statewide trials in 2001 and elite trials throughout Idaho in Registration of ‘Tetonia’ Barley
