Abstract ‘MN‐Rothsay’ (Reg. No. CV‐1208, PI 702731) hard red spring wheat ( Triticum aestivum ) was released by the University of Minnesota Agricultural Experiment Station in 2022 because of its high grain yield and lodging resistance. MN‐Rothsay is a medium‐late maturity cultivar with below average plant height, containing the semi‐dwarfing alleles Rht‐B1b and Rht24b . The lodging resistance of MN‐Rothsay is similar to ‘Linkert’, a 2013 release that was the most widely grown cultivar in Minnesota from 2016 to 2020, largely due to its superior lodging resistance. MN‐Rothsay has moderate resistance to Fusarium head blight (caused primarily by Fusarium graminearum Schwabe), good resistance to prevalent races of pathogens causing leaf rust ( Puccinia triticina Eriks.) and stem rust ( P. graminis Pers.: Pers. f. sp. tritici Eriks. & E. Henn.), and is well‐adapted to the north central United States.
