The genetic resources of and within crop species and their wild relatives form the basis of our food production system. They allow varieties to evolve and adapt to changing conditions and are valuable for further breeding programs. However, the genetic diversity of plants is currently decreasing. Hence, it is important to preserve as much of our genetic heritage as possible. During our summer school on agrobiodiversity in Hungary, we had the opportunity to visit the country’s largest genebank, the National Centre for Biodiversity and Gene Conservation (NBGK) in Tápiószele.
