Major cultivation challenges affecting the production and resilience of rye are lodging and a much lower harvest index (HI) as compared to wheat. Lodging refers to the displacement of stems from an upright position. As the demandless rye is mainly cultivated on light soils with low fertility and low water holding capacity, drought is a serious challenge in rye production as well.
The natural genetic diversity of rye is the basis to achieve innovative advances, which facilitate to overcome these challenges.
