Abstract

‘Lyon’ (Reg. No. CV-356, PI 673045), a spring, two-row, hulled feed barley (Hordeum vulgare L.) cultivar developed and tested as 05WA-316.K, was released in 2013 by Washington State University (WSU). Lyon was derived from the cross ‘Baronesse’/‘Spaulding’ and selected through single-seed descent from F2 to F4 and pedigree breeding methods from F5 to F6. Lyon was tested in field trials in Pullman, WA, and in multi-environment trials at 8 to 10 locations per year by the WSU Variety Testing Program from 2009 to 2013. In these testing sites, Lyon had a mean grain yield (5699 kg ha−1) that was higher than those of check cultivars ‘Bob’ and Baronesse. Across 37 station years in the Western Regional Spring Barley Nursery, Lyon had an average grain yield of 5284 kg ha−1, which was higher than check cultivars ‘Steptoe’, ‘Harrington’, ‘AC Metcalfe’, and ‘CDC Kindersley’. Lyon showed head emergence significantly earlier than Baronesse, Bob, and ‘Lenetah’ and was 3.3 cm shorter than Bob and 6.1 cm shorter than ‘Champion’. Similar to Champion and Baronesse, Lyon is moderately susceptible to stripe rust (caused by Puccinia striiformis f. sp. hordei Eriks.). Lyon is intended as a high-yielding replacement to barley feed cultivars Bob, Baronesse, and Lenetah in the dryland cropping regions of eastern Washington that receive an average precipitation of 400 mm yr−1 or higher.
