Mixed cropping is the simultaneous cultivation of two or more crops in the same field. Mixed cropping, especially of legume and non-legume plants, has been shown to produce higher and more stable yields than the cultivation of a single crop alone. Breeding for mixed cropping bears the potential to further improve yields in this system and its feasibility was investigated in this thesis. Computer simulations as well as field trials were carried out to clarify important questions on this path. Efficient experimental designs as well as concepts for breeding for mixed cropping were developed. Key empirical findings include the identification of key-traits for indirect selection of pea for mixed cropping, the determination of the size of interaction between genotypes and the identification of heterogeneous material as a potential future pathway to further improve yield stability. The results will contribute to the advance of mixed cropping as a sustainable farming practice and thus help to mitigate the challenges agriculture is facing in the 21st century.
