Use of Near Infrared Reflectance Spectroscopy to Evaluate Quality Characteristics in Whole-Wheat Grain

The aim of this work was to explore the potential of visible (Vis) and near infrared reflectance (NIR) spectroscopy to measure quality characteristics in whole grain wheat (Triticum aestivum L.) as a tool in breeding programs. A total of 100 samples were analyzed by the reference methods for crude p...
