Registration of 'Eve' Winter Hulless Barley

'Eve' (Reg. No. CV-350, PI 659067), a six-row, winter hulless barley (Hordeum vulgare L.) developed and tested as VA01H-68 by the Virginia Agricultural Experiment Station, was released in May 2007. Eve was derived from the cross SC860974/VA94-42-13 using a modified bulk-breeding method. It was evaluated in the 2009-2011 Virginia Official Variety Trial in replicated tests at five to six locations. Eve had an average grain yield (3718 kg ha(-1)) that was higher than those of the hulless check cultivars Dan and Doyce. The average grain volume weight of Eve (73.8 kg hL(-1)) over the same period was higher than that of Doyce (68.9 kg hL(-1)). The head emergence of Eve is 6 d earlier than Dan and 'Thoroughbred', which is the predominant barley cultivar grown in the eastern United States. Earlier maturity is a primary factor determining whether barley or wheat (Triticum aestivum L.) is used in double-cropping systems with soybean (Glycine max L.). The grain of Eve has high starch (60.4%) and protein (10.1%) concentration. Eve is the first winter hulless barley released in the eastern United States having a high level of resistance to Fusarium head blight [FHB; caused by Fusarium graminearum (Schwabe)] and reduced accumulation of the mycotoxin deoxnivalenol in the grain. Eve's unique grain composition and resistance to FHB make it desirable as a commodity for food, feed, and ethanol production.
