'SY Clearstone 2CL' (Reg. No. CV-1094, PI 668090) hard red winter wheat (Triticum aestivum L.) was developed by the Montana Agricultural Experiment Station and released in September 2012 through a marketing agreement with Syngenta Seeds. SY Clearstone 2CL is a two-gene Clearfield backcross-derivative of 'Yellowstone' (PI 643428) hard red winter wheat with resistance to imazamox herbicide Beyond (BASF Corporation). SY Clearstone 2CL was selected from the cross Yellowstone*4/3/MTCL01158/Teal 11A//'Jagalene' (PI 631376). Yellowstone is a high-yielding hard red winter wheat released by the Montana Agricultural Experiment Station in 2006. MTCL01158 is an unreleased doubled haploid breeding line [TX12588*4/FS2//Tiber (PI 517194)], which served as the source of proprietary mutant allele TaAHASL1D. Proprietary hard red spring wheat germplasm line Teal 11A (BASF Corporation) served as the source of mutant gene TaAHASL1B. Alleles for herbicide resistance were selected during the backcross process using single-nucleotide, allelespecific polymerase chain reaction markers for TaAHASL1D and TaAHASL1B developed by BASF. SY Clearstone 2CL was selected as an F2:4 line in 2009 following three generations of screening of the backcross population with imazamox herbicide. Results of three years of replicated field testing indicate that SY Clearstone 2CL is similar to recurrent parent Yellowstone for grain yield, most agronomic characteristics, and milling and baking qualities. © Crop Science Society of America.

'Warhorse' (Reg. No. CV-1096, PI 670157) hard red winter (HRW) wheat (Triticum aestivum L.) was developed and released by the Montana Agricultural Experiment Station in September 2013. Warhorse is of unknown pedigree, derived from a composite of three topcrosses made to the same F1 population in 2000: MT9908//'Nuplains'/MTS9862; Nuplains/ MTS9862//MTW0047; and Nuplains/MTS9862//MTS0028. Warhorse was developed using a modified bulk breeding method and selected as an F5:6 headrow. Warhorse was tested under the experimental number MTS0808 from 2008 to 2013 in Montana. Quality was evaluated in multilocation Montana trials since 2008. Warhorse is a solid-stem, high-yielding HRW wheat line with medium to high test weight, medium maturity, reduced height (Rht-B1b), medium to high grain protein, and acceptable milling and baking quality. Warhorse was released for its improved host plant resistance to wheat stem sawfly (Cephus cinctus Nort.) conditioned by stem solidness, along with short stature and improved yield potential relative to existing solid-stem cultivars adapted to Montana. © Crop Science Society of America.

'WB3768' (Reg. No. CV-1100, PI 670158) hard white winter wheat (Triticum aestivum L.) was developed and released by the Montana Agricultural Experiment Station in September 2013. An exclusive license for commercialization of WB3768 was granted to Monsanto. WB3768 is of unknown pedigree, derived from a composite of two related topcrosses: MTW0047 ('Judith'/PI 262605//S86-740)/2*MT9982 and MTW0047/MT9982//MT9989 (Judith/'Arapahoe'). MT9982 is a sib selection of 'Yellowstone', and S86-740 ('Norstar'/Plainsman V'//'Ulianovkia') is an unreleased breeding line developed by the Crop Development Center in Saskatoon, Saskatchewan. WB3768 was developed using a modified bulk breeding method and selected as an F5:6 headrow. WB3768 was tested under the experimental number MTW08168 in Montana yield trials from 2009 to 2013. WB3768 is a high-yielding, winterhardy, conventional-height hard white winter wheat line with late maturity, medium to high grain protein, low polyphenol oxidase activity, and acceptable milling and baking quality. WB3768 was released for its combination of the hard white market class and excellent yield performance in winter wheat production environments of Montana. © Crop Science Society of America.

'Decade' (Reg. No. CV-1058, PI 660291) hard red winter (HRW) wheat (Triticum aestivum L.) was developed and released jointly by the Montana and North Dakota Agricultural Experiment Stations in September 2010. Decade is of unknown pedigree derived from a composite of three closely related single crosses (N95L159/'CDC Clair', N95L159/MT9602, and N95L159/MT9609). Decade was developed using a modified bulk-breeding method, selected as an F5:7 headrow, and tested under the experimental number MT0552 from 2005 to 2009 in Montana and from 2008 to 2009 in North Dakota. Quality has been evaluated in multilocation Montana trials since 2005. Decade is a high-yielding, winter-hardy HRW wheat line with medium to high test weight, early maturity, reduced height (Rht-B1b), medium to high grain protein, and excellent milling and baking quality. The line was released for its combination of good winter hardiness, short stature, and high yield potential and for its excellent performance in the eastern Montana and western North Dakota winterwheat production environments. © Crop Science Society of America.

‘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 F5:7 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. © Crop Science Society of America. All rights reserved. Source
