ResumoFusarium head blight (FHB) (caused primarily by Fusarium graminearum Schwabe) is a disease that annually threatens wheat (Triticum aestivum L.) grown in the northern plains of the United States. Resistance to this disease is a high priority trait in the University of Minnesota's spring wheat breeding program. We utilized marker-assisted selection in the F6 (pre-yield trial stage) generation to identify lines containing Fhb1, a major quantitative trait locus for FHB resistance. One line, tested as MN05214-3 in Minnesota statewide yield trials from 2008 to 2010 and in the Uniform Hard Red Spring Wheat Regional Nursery in 2009 and 2010, was released as ‘Rollag’ (Reg. No. CV-1107, PI 665250) by the University of Minnesota Agricultural Experiment Station in 2011. Rollag is a mid-maturity, semidwarf cultivar that has above-average grain protein content. Rollag was released on the basis of its good resistance to FHB, resistance to lodging, competitive grain yield and acceptable end-use quality characteristics. Rollag is well adapted to hard red spring wheat growing regions in Minnesota and the Upper Midwest.
