Summary

Evolutionary breeding through the introduction of composite cross populations (CCPs)encourages intra-specific diversity and increases diversity in the agricultural landscape. Increased genetic diversity in crops may help to buffer both biotic and abiotic stresses and will play an increasingly important role in unpredictable climatic conditions become more unpredictable (Østergård et al. 2009). A number of CC winter wheat populations, commercial varieties and CCP line selections were tested at the University of Kassel, under differing N input levels in order to test past adaptation and suitability to differing fertilisation levels. The CCPs have been managed since 2005 under both organic and conventional conditions without conscious selection.
Genetically diverse CCPs have the ability to be able to adapt to their environment, which may also include the management system, meaning that CCPs grown under
conventional conditions may be better suited to growing conditions with higher N inputs, in comparison to CCPs, which have been managed organically under low N levels.
