CHARACTERIZATION OF WHEAT BY 4 ANALYTICAL PARAMETERS - A CHEMOMETRIC STUDY

The results of chemical analysis (ashes, humidity, fat and proteins) c arried out on 195 samples of wheat of two different classes (Triticum durum and Triticum vulgare or Triticum aestivum), and from different g eographical areas, variety and year of production, were evaluated by p rincipal component analysis (PCA) and classification analysis. Pattern s of samples of the same species, variety and from the same origin wer e displayed by principal component plots. By means of classification a nalysis, best results (classification and prediction abilities greater than or equal to 90%) were achieved by discriminating between the two species and origin, also the discrimination among varieties and years of harvesting was generally successful.
