Registration of ‘MN‐Washburn’ hard red spring wheat containing Barley yellow dwarf virus resistance gene bdv2

Abstract

Abstract‘MN‐Washburn’ (Reg. no. CV‐1184, PI 694049) hard red spring wheat (Triticum aestivum L.) 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. MN‐Washburn also had good disease resistance, including resistance to Barley yellow dwarf virus (BYDV) and field resistance to the Ug99 race group of stem rust. 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 plant height due to the semi‐dwarfing genes Rht‐B1 and Rht24. MN‐Washburn has good resistance to prevalent races of pathogens causing leaf rust, stripe rust, and stem rust and is well‐adapted to the north central United States.
