- Analytical methods for crop quality determination

Section on Breeding for Quality Characters:
- Genetics of quality characters and quality breeding goals
- Wheat and rye (bread making quality)
- Malting barley, durum wheat and other special-use-cereals
- Oilseed rape and sunflower (oil content, fatty acid profile, ANF´s etc.)
