Near infrared spectroscopy (NIR)-spectroscopy, colour measurement and single kernel characterization in rye breeding

Breeding relevant methods were developed or adapted for a comprehensive characterization of rye quality. In addition to classical chemical methods, necessary for calibration ofNIR-spectrometer, a single kernel characterization system (SKCS) and a colour measuring instrument was used. NIR calibrations are calculated for yield, weight, size, shape and hardness (toughness) of rye grains, composition (protein, starch and arabinoxylans), colour and sprouting parameters.
