Optimisation of the potential of semi-dwarfs in rye for increasing the climate protection performance of cereal crop rotations (PRoKlima)
Objective
Further development and assessment of semi-dwarfs with defined grain qualities to improve sustainability and climate-friendly production of bread and feed grain
Methodology
- 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
