Interpretive Summary: Spring planted wheat is an important crop in Minnesota. Wheat cultivars grown in Minnesota need to have good levels of protein and other bread making and milling characteristics in order to meet standards needed by the flour milling industry. In addition wheat cultivars need to have high yield and be resistant to diseases caused by fungi, bacteria and viruses. The wheat cultivar MN-Washburn released in 2019, has good bread making quality characteristics, high yield, and good resistance to diseases. This cultivar is also notable for having resistance to barley-yellow dwarf virus.

Technical Abstract: 'MN-Washburn' hard red spring wheat was released by the University of Minnesota Agricultural Experiment Station in 2019 because of its high grain yield, good lodging resistance and end-use quality characteristics, and good disease resistance, including resistance to Barley Yellow Dwarf Virus (BYDV). The BYDV resistance of MN-Washburn results from the introgression of a chromosome 7D translocation containing Thinopyrum intermedium resistance gene bdv2 from the introgression line TC14. MN-Washburn is a mid-late maturity cultivar with below average planting height due to the semi-dwarfing gene Rht-B1. MN-Washburn has good resistance to prevalent races of leaf rust (Puccinia triticina Eriks.), stripe rust (Puccinia striiformis Westend. f. sp. tritici Eriks.), and stem rust (Puccinia graminis Pers.: Pers. f. sp. tritici Eriks. & E. Henn.) and is well-adapted to the north central U.S.
