Optimisation of the potential of semi-dwarfs in rye for increasing the climate protection performance of cereal crop rotations (PRoKlima)


Further development and assessment of semi-dwarfs with defined grain qualities to improve sustainability and climate-friendly production of bread and feed grain



  • Crossing of the short-straw gene Ddw1 into population rye and investigations on root system, drought stress tolerance and yield physiological parameters
  • Phenotyping of semi-dwarfs under current and predicted future climatic conditions (field and pot trials)
  • Integration of agro-ecosystem models and life cycle assessment for comprehensive greenhouse gas accounting of rye under climate change


Climate effect under consideration

Reduction of GHG emissions from rye production through improved N-efficiency and reduced consumption of fossil fuels during harvesting
