Registration of 'MT Sidney' hard red spring wheat

'MT Sidney' (Reg. no. CV-1199; PI 699957) hard red spring wheat (Triticum aestivum L.) was released by the Montana Agricultural Experiment Station in January 2021 as a new cultivar adapted to Montana's rainfed growing environments. MT Sidney was a selection from the cross MT1274/'RB07' and was tested in Montana as experimental line MT1716 from 2018 to 2020. MT1274 is an unreleased, Montana experimental line, and RB07 was released by the University of Minnesota in 2007 for high yield, moderate Fusarium head blight (FHB) resistance, and good end-use quality. MT Sidney was in the top-yielding statistical group in our advanced yield trial that includes 'Vida' (PI 642366), the most widely grown cultivar in Montana. MT Sidney also has significantly higher test weight and an earlier heading date than Vida. Multiple years of FHB resistance screening indicate MT Sidney is moderately resistant to FHB. MT Sidney was released based on high yield potential, high test weight, early heading date, and moderate FHB resistance.
