Six-rowed, rough awned, midseason, erect growing, spring feed barley. Aleurone color white. 1000-kernel weight averages 39g. Compared to Steptoe, equal in heading date, roughly 4cm taller (88 vs. 92 cm) but has much stronger straw (11 vs. 51% lodging for Steptoe). Grain yield equal to Steptoe (6478 kg/ha in Utah tests and 4680 kg/ha in Western Regional Spring Barley tests). Test weight and protein exceeds Steptoe (651.2 vs. 626.8 kg m-3 and 12.64 vs. 11.36% respectively). Field resistance to barley loose smut and covered smut. Moderate resistance to powdery mildew.
