Available at: http://wheat.pw.usda.gov/ggpages/oatnewsletter/v46/#Youngs Technical Abstract: Youngs 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 Youngs is ND863443/ND852163. ND863443 was developed with the pedigree W80-20/Porter. W80-20 is a breeding line from the Winnipeg Agriculture and Agri-Foods Canada program that possessed the stem rust resistance gene pg-13 and crown rust resistance genes Pc-55 and Pc-56. ND852163 was developed with the pedigree W80-20/ND811724. ND811724 was developed with the pedigree CA6/Hudson//Dal. CA6 is a line from the Minnesota recurrent selection for grain yield. Based on four years of evaluation at nine locations in North Dakota variety trials, Youngs had high average grain yield and excellent test weights. Youngs is late maturing and is a tall cultivar, but exhibits good lodging resistance relative to its height. Youngs produces large white kernels with a good groat percentage. Youngs has moderate groat protein and low groat oil concentrations, but has higher groat beta-glucan concentration than any other cultivar adapted to North Dakota. It has moderate crown rust resistance and moderate tolerance to barley yellow dwarf virus. Youngs is protected from the prevalent races of stem rust by the gene pg-13. The name Youngs was chosen to recognize the contributions to oat quality improvement of Dr. Vernon Youngs, the first director of the USDA Oat Quality Laboratory at Madison, Wisconsin and later became the director of the USDA Wheat Quality Laboratory in Fargo, North Dakota. Youngs will be protected under the U.S. Plant Variety Protection Act without the Title V option.
