Crop Wild Relative (CWR): “A wild plant taxon that has an indirect use derived from its relatively close genetic relationship to a crop; this relationship is defined in terms of the CWR belonging to gene pools 1 or 2, or taxon groups 1 to 4 of the crop. CWR include crop progenitors and can broadly be described as any taxon in the same genus (or closely related genera) as a crop” (ECPGR Concept for in situ conservation of crop wild relatives in Europe, Maxted et al. 2015).
Ex situ conservation: “[…] means the conservation of components of biological diversity outside their natural habitats”. Convention on Biological Diversity, Article 2 (1992).
Genetic resources: “[…] means genetic material of actual or potential value.” Convention on Biological Diversity, Article 2 (1992) (“Genetic material” means any material of plant, animal, microbial or other origin containing functional units of heredity.).
In situ conservation: “[…] the conservation of ecosystems and natural habitats and the maintenance and recovery of viable populations of species in their natural surroundings and, in the case of domesticated or cultivated species, in the surroundings where they have developed their distinctive properties.” Convention on Biological Diversity, Article 2 (1992).
Wild Food Plant (WFP): Non-cultivated populations of wild plants species that grow spontaneously in their natural habitat and are used as human food.
