Farmers and immigrants brought promising plant varieties and livestock breeds to the US long before the USDA started an official program to preserve these valuable genetic resources.  Genebanking in the US officially began in the 1890s with the establishment of Plant Introduction Stations around the country to evaluate  plants with interesting traits. The first ”official” plant introduction (PI) was a cabbage (Brassica oleraceae) from Siberia.

The National Seed Storage Laboratory (NSSL) was built in 1958 to consolidate plant collections from PI stations, plant collectors and publicly-funded breeders into a single facility that used state-of-art practices to maintain viability and data associated with sample provenance.

The first researchers at NSSL began long term studies to inform us about how water and temperature contributed to shelf life of seeds and how these parameters had different effects on different species. The results of this research led to the bold (at the time) move in 1977 to convert seed storage vaults from refrigerators (5°C) to freezers (-18°C).

Application of the modern field of cryobiology (just established in the 1950s) to plants led to experiments to test whether seeds could be stored in liquid nitrogen.  These experiments were begun in 1977, but by 1990, liquid nitrogen storage was routine.  Preservation of vegetative cuttings and recalcitrant seeds (germplasm that requires water to survive) was now possible with the cryogenic facilities at NSSL.

In 1992, the NSSL building was expanded and the capacity to store germplasm increased ten-fold.

The core knowledge about genebanking and preservation, access to liquid nitrogen storage facilities, and high security at the renovated NSSL facility made it an attractive place to establish USDA’s first animal genebank, the National Animal Germplasm Program (NAGP), which was initiated in 1999.

The National Seed Storage Laboratory’s expanded mission to preserve more than just seeds and more than just plant genetic resources, prompted the designation of the facility as a Center, hence the name change to the National Center for Genetic Resources Preservation (NCGRP) in 2002.  NCGRP now carries the mission of preserving germplasm of all life forms that are important to US agriculture.
