Registration of ‘Decade’ Wheat

Abstract

‘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 winter‐wheat production environments.
