Item TAMFT‐3A and TAMFT‐3B2 homeologs are associated with wheat preharvest sprouting(Wiley, 2022-08) Vetch, Justin Michael; Tillett, Brandon J.; Bruckner, Phil L.; Martin, John M.; Marlowe, Karol; Hooker, Marcus Alan; See, Deven Robert; Giroux, Michael J.The phenomenon of preharvest sprouting (PHS), caused by rain after physiological maturity and prior to harvest, negatively affects wheat (Triticum aestivum L.) production and end use. Investigating the genetics that control PHS resistance may result in increased control of seed dormancy. Multiple genes involved in the development of seed dormancy are associated with PHS. In this study, the TaMFT (3A, 3B1, 3B2, 3D), TaMKK3-4A, and TaVP1-3B genes were assessed for association with PHS in a double-haploid line (DHL) hard red winter wheat population derived from a BC1 cross between the cultivars Loma and Warhorse, where Loma was the recurrent and PHS susceptible parent. The 162 BC1 DHL lines were grown over two field seasons and PHS susceptibility was assessed by measuring PHS resistance in physiologically mature heads. The PHS variation was associated with the TaMFT-A and the B2 homeolog with Loma carrying mutant forms of each gene. No sequence variation between Loma and Warhorse was detected in the exons of the TaMFT-B1 and D homeologs. No association between PHS resistance and TaMKK3-4A or TaVp1-3B variation was observed, though Loma and Warhorse vary for TaMKK3-4A and TaVp1-3B mutations reported to be PHS associated. Previous research has shown TaMFT-3A as having a large impact on PHS resistance. In the current study, the TaMFT-3A and TaMFT-3B2 alleles each explained 14% of observed PHS variation. Markers for both TaMFT-3A and TaMFT-3B2 should be used in selecting for increased wheat dormancy and PHS resistance.Item 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.Item 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.
