Technical Abstract: ‘Ulen’ is a hard red spring wheat (Triticum aestivum L.) cultivar developed and released by the Minnesota Agricultural Experiment Station in cooperation with USDA-ARS in January 2005. Ulen was released on the basis of its high grain yield, high grain protein content, and early maturity. Ulen was derived from the cross MN92044/HJ98, made in 1994. The F2 population producing Ulen was selected for leaf rust and stem rust resistance in a field planting at St. Paul in 1995. The F3 generation was advanced by single seed descent in a greenhouse. The selection resulting in Ulen was a single plant selected for leaf and stem rust resistance and acceptable plant height from an F4 headrow in 1996. This selection was tested under the experimental designation MN97803 in yield trials from 1997 through 2001 and following purification as MN97803-A in 2002 through 2004. Approximately 1,000 kg of Breeder seed of MN97803-A was produced in 2002 by the Minnesota Crop Improvement Association and further increased in Minnesota in 2003 and 2004. MN97803-A was released as Ulen in 2005. Ulen was evaluated in 21 environments in Minnesota, North Dakota, and South Dakota in the Uniform Regional Hard Red Spring Wheat Nursery in 2000 and 2001 and yielded an average of 3597 kg ha-1 compared to an average of 3306 and 3496 kg ha-1 produced by the check cultivars, ‘2375’ (PI 601477, syn. Pioneer 2375) and ‘Verde’ (PI 592561, respectively. Ulen is moderately susceptible to Fusarium head blight. The USDA Spring Wheat Quality Laboratory, Fargo, ND evaluated bread-making properties of Ulen grown in a total of 13 environments from 2001 thru 2003. The Minnesota Agricultural Experiment Station, St. Paul, MN 55108, will maintain Breeder seed of Ulen. Foundation seed will be produced and maintained by the Minnesota Crop Improvement Association, 1900 Hendon Ave., St. Paul, MN 55108.
