Interpretive Summary: A new hulless barley variety was released from the VA agricultural experiment station in March 2010. This paper describes the characteristics that make it unique. Briefly, it was higher yielding had a higher density and a high starch concentration and was resistant to Fusarium head blight.

Technical Abstract: Dan’ (Reg. No. CV- , PI 659066) six-rowed winter hulless barley (Hordeum vulgare L.) was developed and released by the Virginia Agricultural Experiment Station in March 2009. Dan was derived from the cross VA96-41-17 / SC872143. It was released for production in the eastern United States, as a potential commodity for fuel ethanol, food, and feed production. In Virginia’s Official State Variety Trial, Dan had an average (2007-2009) grain yield of 3564 kg ha-1 that was higher than those of the hulless cultivars Eve (3359 kg ha-1) and Doyce (3209 kg ha-1). Dan had the highest average grain volume weight (78.3 kg hl-1), which was significantly (P < 0.05) higher than those of Eve (75.7 kg hl-1) and Doyce (70.0 kg hl-1). Grain of Dan had an average starch concentration (66.2%) that exceeded those of Doyce (62.7%) and Eve (60.4%). Dan provides barley producers and end users in the eastern U.S. with a widely adapted, winter-hardy hulless cultivar having superior grain quality and resistance to Fusarium Head Blight (Fusarium graminearum).
