Bread wheat breeding lines from yield and elite yield trials are analyzed annually for grain quality traits at the Wheat Chemistry and Quality Laboratory of CIMMYT. The analysis done are the following: grain morphology (test weight and thousand kernel weight), grain hardness and protein content, flour yield, flour protein content, SDS-sedimentation test, mixograph, alveograph and bread-making. Based on this data breeding lines combining good agronomic performance and desirable processing and end-use quality are selected and move forward in the breeding process.
