'Duclair' hard red spring wheat (Triticum aestivum L.) (Reg. No. CV-1060, PI 660981) was developed by the Montana Agricultural Experiment Station and released in 2011. The objective for the development of Duclair was to provide a solid-stemmed, semidwarf cultivar for areas infested by the wheat stem sawfly (Cephus cinctus Nort.). Duclair was developed through initial generations of single seed descent of F2 seed from a 'Choteau'/MT0249 cross. Progeny lines were selected to have solid stems from Choteau, and extended green leaf duration from MT0249. Duclair was tested as MT0832 at sites across Montana in 2008, 2009, and 2010. Stem solidity of Duclair is similar to the solid-stemmed cultivar 'Fortuna' and slightly less than 'Choteau'. Duclair has shown good yield potential throughout Montana and its height is more desirable for dry conditions than Choteau. Duclair has grain protein levels similar to other hard red spring wheat cultivars and acceptable milling and baking characteristics. Duclair will be of interest to wheat growers in sawfly-infested areas of Montana and adjoining regions. © Crop Science Society of America.

'Egan'q 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 Gehin). 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. © Crop Science Society of America. All rights reserved.

'WB9879CLP' hard red spring wheat (Triticum aestivum L.) (Reg. No. CV-1086, PI 666046) was developed by the Montana Agricultural Experiment Station and released in 2012 to the commercial partner Westbred, a subsidiary of Monsanto. WB9879CLP is a two-gene Clearfield wheat for use with the imidazolinone herbicide Beyond (BASF). WB9879CLP was developed by backcrossing alleles for resistance to the imidazolinone herbicide class into the recurrent parent 'Choteau'. Choteau has solid stems, which provide resistance to the wheat stem sawfly (Cephus cinctus Nort.). The wheat stem sawfly is a major yield-reducing pest in large areas of Montana and surrounding regions. Alleles for herbicide resistance at TaAHAS1D and TaAHAS1B were selected during the backcrossing process and line derivation using polymerase chain reaction markers developed by BASF. Two years of replicated yield trials at a total of 16 sites showed that WB9879CLP is similar to Choteau in most agronomic characteristics. WB9879CLP showed no symptoms of damage at any of 13 testing sites when imidazolinone herbicide was applied at two times the recommended rate. WB9879CLP is the first Clearfield solid-stem wheat variety for sawfly infested sites in Montana and adjoining regions. © Crop Science Society of America.
