Technical Abstract: Ebeltoft spring oat was developed cooperatively by the North Dakota Agricultural Experiment Station and the USDA-ARS and was released in June 1999. The pedigree of Ebeltoft is NZ C9,01/ND863443. NZ C9,01 is a germplasm line provided by Keith Armstrong from the New Zealand program and ND863443 was developed with the pedigree W80-20/Porter. W80-20 is a breeding line from the Winnipeg program that contributed the stem rust resistance gene pg-13 and possessed the crown rust resistance genes Pc-55 and Pc-56. Based on three years of evaluation at nine locations in North Dakota variety trials, Ebeltoft had high average grain yield and maintained excellent test weights. Ebeltoft is late maturing and is considered medium height. Ebeltoft produces large kernels with ivory colored hulls. It has good groat percentage, higher than average protein and lower than average oil concentrations. Ebeltoft exhibited moderate resistance to the crown rust races present in North Dakota during its evaluation and moderate tolerance to barley yellow dwarf virus. Ebeltoft is protected from the prevalent races of stem rust by resistance conferred by pg-13, but Ebeltoft is susceptible to stem rust race NA67. The name Ebeltoft was chosen to recognize the contributions of Dr. David Ebeltoft, who worked in oat breeding during the 1960s and developed Dawn and Wyndmere spring oats. Ebeltoft will be protected under the U.S. Plant Variety Protection Act without the Title V option.
