  • Germplasm is living tissue from which new plants can be grown.
  • NBPGR is meeting the need of in-situ and ex-situ germplasm conservation through Delhi Headquarters and 10 regional stations in the country.
  • In situ and ex situ conservation focuses on the maintenance of species diversity within or away from their natural habitats, respectively.
  • Presently, it is protecting 4.52 lakh accessions, of which 2.7 lakh are Indian germplasm and the rest have been imported from other countries.
  • An accession is a single, collected variety or varieties of a wild plant, a landrace or a plant variety that has been produced by selective breeding, more commonly known as a cultivar.
  • The NGB has four kinds of facilities, namely, Seed Genebank (- 18°C), Cryogenebank (-170°C to -196°C), In vitro Genebank (25°C) and Field Genebank, to cater to long-term as well as medium-term conservation.
  • It stores different crop groups such as cereals, millets, medicinal and aromatic plants and narcotics, etc.
