Summary

Unpredictable climatic conditions and increasing pressure on non-renewable resources mean that alternative agricultural systems able to cope with increasing biotic and abiotic stresses, as well as external input costs, are needed. Sustainable agricultural systems should be self-regulating, characterized by a high degree of interand intra-specific diversity (Moreau 2010). Evolutionary breeding through the introduction of Composite Cross Populations (CCPs) increases intra-specific diversity, enabling CCPs to adapt to changing environmental conditions. Increasing interspecific diversity, through mixed cropping, also plays an important role in sustainable systems and suitable crops are needed that are able to cope with the increasing interspecific competition found in these mixed systems. A number of winter wheat CCPs, lines and commercial varieties were tested with white clover as an undersowing in order to test competitive ability and performance.
