During the middle of last century, triggered by the realization that genetic erosion was threatening the existing landraces and wild relatives of the major food crops, global efforts to collect and conserve the genetic diversity of these threatened resources were initiated, predominantly orchestrated by FAO. National and international genebanks were established to store and maintain germplasm materials, Citation: Engels, J.M.M.; Ebert, A.W. conservation methodologies were created, standards developed, and coordinating efforts were put in A Critical Review of the Current place to ensure effective and efficient approaches and collaboration. In the spontaneously developing Global Ex Situ Conservation System global conservation system, plant breeders played an important role, aiming at the availability of for Plant Agrobiodiversity. I. History genetic diversity in their breeding work. Furthermore, long-term conservation and the safety of of the Development of the Global the collected materials were the other two overriding criteria that led to the emerging international System in the Context of the network of ex situ base collections.
