| Alternative breeding approaches in organic agriculture have started to address pressing issues such as the lack of appropriate plant varieties particularly suited to cope with higher biotic and abiotic stresses, generally found in low-input and organic production systems. This challenge, coupled with the additional pressure of loss of plant genetic diversity, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity. This High genetic Diversity (Hi-D) approach is relevant to organic agricultural systems for two reasons; firstly the availability of diverse germplasm improves chances of finding germplasm suited for low-input conditions as found in... |

| A lack of appropriate crop varieties specifically bred for the higher biotic and abiotic stresses experienced in organic and low-input systems, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity. The creation of CCPs using carefully chosen parental varieties, coupled with the ability of the populations to adapt to local environments means that these populations are well suited for low-input and organic agricultural systems (Phillips and Wolfe, 2005). COBRA (Coordinating Organic plant BReeding Activities for Diversity) aims to “support and develop plant breeding and seed production in Europe by increasing the use of plant material with High... |

| Thirteen winter wheat composite cross populations originating from one population but with differing histories over six years and three reference varieties were compared for yield, disease occurrence, as well as phenotypic diversity. The populations performed similarly and often better than the reference varieties in terms of yield and had lower incidence of disease. The populations are also phenotypically diverse and differ among each other, indicating that they have maintained a high degree of diversity over time and in varying locations, but most likely also diverged from each other. |
