Description: ‘Choteau’ (Reg. no. CV-955, PI 633974) is a superior yielding, wheat stem sawfly (Cephus cinctus Nort.) resistant hard red spring wheat (Triticum aestivum L.) developed by the Montana Agricultural Experiment Station and released in February 2003. Choteau is targeted for production in areas of Montana infested with the wheat stem sawfly. Choteau has lax and tapering heads with white awns and glumes. Glumes are acuminate and the shoulder is wanting. Kernels are red, ovate, and have a medium brush. Kernels have a medium crease with rounded cheeks. Anthocyanin is absent in the coleoptile and the flag leaf is erect. Mature plant color is white. Creation: Choteau was derived as an F4 plant selection from the cross MT 9401/MT 9328. MT 9401 was a selection from the cross MT 8603/‘Amidon’ (PI 527682). MT 8603 was derived from the cross MT 7635/‘Nacozari’. MT 9328 was a selection from the cross MT 7810/MT7926. MT 7810 [‘Tezanos Pintos Precos’/‘Sonora 64’//‘Fortuna’ (PI 13596)] was a sister line to ‘Glenman’ (McNeal et al., 1985). MT 7926 was derived from a cross between an experimental line from North Dakota State University with unknown pedigree and MT 6830. MT 6830 has the pedigree ‘Sheridan’ (CI 13586)//CI 13253/5*‘Centana’ (CI 12974). Country: USA Yeld: Mean grain yield of Choteau over 28 location/years was 4414 kg ha–1 Go to Tables of wheat varietes
