Germplasm Collection(s)

Global sweetpotato genetic diversity is maintained in a number of gene banks around the world. These contain various types of germplasm, ranging from wild relatives to cultivated varieties, including farmers landrace varieties, old varieties, currently important cultivars, and breeding materials. Because sweetpotato is a clonally propagated crop, typically sweetpotato germplasm is in clonal form (maintained in tissue culture, frozen, or as living plants in a greenhouse or field gene bank). Sweetpotato genetic resources may also be maintained as populations of seed; typcially the case for wild relatives and populations from breeding programs. There are many sweetpotato gene banks around the world, typically with information about sources and characteristics of the germplasm in them. We provide here information and links to gene banks and to sources of information about sweetpotato germplasm, including guidelines on sweetpotato germplasm characterization and gene bank management.
