Registration of ‘Duclair’ Hard Red Spring Wheat

Abstract

‘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.
