(Wiley, 2020-06) Bruckner, Phil L.; Berg, Jim E.; Lamb, Peggy F.; Kephart, Ken D.; Eberly, J. O.; Miller, John H.; Chen, C.; Torrion, J. A.; Pradhan, G. P.; Ramsfield, R.; Nash, Deanna L.; Holen, D. L.; Cook, J. P.; Gale, S.; Jin, Y.; Kolmer, J.; Chen, X.; Bai, G.
‘Bobcat’ (Reg. no. CV-1161, PI 693235) hard red winter (HRW) wheat (TriticumaestivumL.) was developed and released by the Montana Agricultural Experiment Station in September 2019. Bobcat is of unknown pedigree, derived from a composite of two related single crosses made in 2007: MT0598/98X366-E29-1and 01X258-C1/MT0598. MT0598 is an unreleased, hollow-stem experimental line,and98X366-E29-1and01X258-C1areunreleased,Montana solid-stem experimental lines. Bobcat was developed using a modified bulk breeding method and selected as an F5:6head row. Bobcat was tested under the experimental numberMTS1588 from 2015 to 2019 in Montana. Quality was evaluated in multilocation Montana trials since 2015. Bobcat is a solid-stem, high-yielding HRW wheat cultivar with medium to high test weight, medium maturity, reduced height (Rht-B1b), medium to high grain protein, and acceptable milling and baking quality.Bobcat was released for its improved host plant resistance to wheat stem sawfly(Cephus cinctusNort.) conditioned by stem solidness, along with short stature,and improved yield potential relative to ‘Warhorse’, the current predominant solid-stem cultivar in Montana.

‘Flathead’ (Reg. no. CV-1164, PI 693237) hard red winter (HRW) wheat (TriticumaestivumL.) was developed and released by the Montana Agricultural Experiment Station in 2019. Flathead was derived from a composite of two very closely related single crosses of the predominant cultivar ‘Yellowstone’ to stripe rust resistant source PI 640431, a hard white spring wheat backcross derivative ofWA007900 that carries stripe rust all-stage resistance genesYr5andYr15.Flat-head was developed using a modified bulk breeding method and selected as anF5:6head row after phenotypic selection for stripe rust resistance at Kalispell,MT. Flathead was tested under the experimental number MT1564 in Montana yield trials from 2015 to 2019. Flathead is a high-yielding HRW wheat cultivar with early maturity,short stature, medium grain protein concentration,excellent milling and baking quality,and a high level of all-stage resistance to predominant races of stripe rust. Flathead was released for its early maturity, improved stripe rust resistance,and improved grain yield relative to other Montana-adapted early heading cultivars.
Registration of ‘Dagmar’ hard red spring wheat
(2020-02) Heo, Hwa-Young; Lanning, Susan P.; Lamb, Peggy F.; Nash, Deanna L.; Wichman, David M.; Eberly, Jed O.; Carr, P.; Kephart, Ken D.; Stougaard, Robert N.; Torrion, Jessica A.; Miller, J.; Chen, Chengci; Holen, Doug L.; Blake, Nancy K.; Talbert, Luther E.
‘Dagmar’ hard red spring wheat (Triticum aestivum L.) (Reg. no. CV‐1158, PI 690450) was released by the Montana Agricultural Experiment Station because of its excellent yield potential in dryland areas of Montana, solid stems, and superior end‐use quality. Dagmar was a selection from the cross MT1133/MT1148 and was tested as experimental line MT1621. Dagmar has similar grain yield potential to ‘Vida’, the most widely grown cultivar in Montana. Stems of Dagmar are more solid than those of Vida, suggesting increased resistance to the wheat stem sawfly (Cephus cinctus Norton). Dagmar has higher grain protein and stronger gluten than Vida. Thus, Dagmar should be useful in Montana and adjoining states facing drought and wheat stem sawfly pressure.
Registration of ‘Egan’ Wheat with Resistance to Orange Wheat Blossom Midge
(2014-08) Blake, Nancy K.; Stougaard, Robert N.; Bohannon, B.; Weaver, David K.; Heo, Hwa-Young; Lamb, Peggy F.; Nash, Deanna L.; Wichman, David M.; Kephart, Ken D.; Miller, John H.; Eckhoff, Joyce L.; Grey, William E.; Reddy, Gadi V. P.; Lanning, Susan P.; Sherman, Jamie D.; Talbert, Luther E.
Egan' hard red spring wheat (Triticum aestivum L.) (Reg. No. 1102, PI 671855) was developed by the Montana Agricultural Experiment Station and released in 2014. Egan is intended for production in areas of Montana infested with the orange wheat blossom midge (OWBM) (Sitodiplosis mosellana Géhin). Egan is resistant to OWBM due to antibiosis conferred by resistance gene Sm1. Egan also contains a chromosome segment originally introgressed into wheat from T. turgidum ssp. dicoccoides containing a gene for high protein (Gpc-B1) and a gene for stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici) resistance (Yr36). Egan has shown high yield potential and high grain protein in nurseries grown under OWBM pressure in the Flathead Valley of Montana. Egan is the first hard red spring wheat cultivar with resistance to OWBM developed for Montana.
Registration of 'Northern' Hard Red Winter Wheat
(2016-05) Berg, Jim E.; Lamb, Peggy F.; Miller, John H.; Wichman, David M.; Kephart, Ken D.; Stougaard, Robert N.; Pradhan, G. P.; Nash, Deanna L.; Grey, William E.; Gettel, D.; Gale, Sam; Jin, Yue; Kolmer, J. A.; Chen, X.; Bai, G.; Murray, T. D.; Bruckner, Phil L.
Northern' (Reg. No. CV-1114, PI 676026) hard red winter wheat (Triticum aestivum L.) was developed and released by the Montana Agricultural Experiment Station in 2015. Northern was derived from a composite of two crosses, MT9982//MTW0072/NW97151 and MTW0047//MTW0072/NW97151. Northern was developed using a modified bulk breeding method and selected as an F-5:7 headrow. Northern was tested under the experimental number MT0978 in Montana yield trials from 2009 to 2015. Like predominant cultivar Yellowstone, Northern is a high-yielding, winter-hardy hard red winter wheat cultivar with medium to late maturity, medium to high grain protein, and acceptable milling and baking quality. Northern was released for its excellent performance in winter wheat production environments of north-central Montana, reduced plant height, and improved grain volume weight and resistance to stem rust (caused by Puccinia graminis Pers.: Pers. f. sp. tritici Eriks. & E. Henn.) relative to Yellowstone.
Registration of ‘StandClear CLP’ hard red winter wheat
(2020-06) Berg, Jim E.; Kephart, Ken D.; Lamb, Peggy F.; Davis, Edward S.; Eberly, Jed O.; Miller, John H.; Chen, Chengci; Pradhan, G. P.; Torrion, Jessica A.; Ramsfield, Ron; Smith, Vincent H.; Nash, Deanna L.; Holen, Doug L.; Cook, Jason P.; Gale, Sam; Jin, Yue; Chen, X.; Bruckner, Phil L.
‘StandClear CLP’ (Reg. no. CV-1162, PI 693236) hard red winter (HRW) wheat (Triticum aestivum L.) was developed and released by the Montana Agricultural Experiment Station and exclusively licensed to Loveland Products, Inc., in 2020. StandClear CLP is a two-gene Clearfield, semisolid-stem wheat intended for use with the selective imidazolinone (IMI) herbicide imazamox. StandClear CLP resulted from a cross of MTS0531 to an IMI herbicide tolerant F1 plant from a population segregating for two acetohydroxyacid synthase (AHAS) genes [TaAHAS1D and TaAHAS1B]. Original herbicide tolerance donors were IMI ‘Fidel’ (TX12588*4/FS2, BASF) for allele TaAHAS1D via descended experimental lines MTCL0309 and MTCL0510, and proprietary hard red spring wheat line CDC Teal 11A (BASF Corporation) for allele TaAHAS1B. StandClear CLP was selected as a F6:7 headrow in 2014 following multiple cycles of phenotypic mass selection for IMI herbicide tolerance and stem solidness. StandClear CLP was tested under the experimental number MTCS1601 from 2016 to 2019 in Montana for field performance, herbicide tolerance, and end-use quality. StandClear CLP is a high-yielding, Clearfield HRW wheat cultivar with intermediate stem solidness, moderate host plant resistance to wheat stem sawfly, and acceptable milling and baking quality.
