Analyses for test weight, 500-kernel weight, protein content, ash content, and hardness characteristics of fractions of 15 samples of hard red winter wheat, obtained by spectrometric separation, revealed high negative correlations in most cases between plumpness factors and protein and ash contents, and high positive correlations between plumpness factors and hardness, when the latter is determined with a single-stage instrument. The projection technique appears to provide a means for analyzing commercially mixed wheat for certain qualities of its components and it may be applied practically to separate either high protein fractions or high test weight fractions from ordinary commercial grain.
