Glasshouse collection of sweet potato germplasm

At Roodeplaat, the ARC also maintains the only disease-indexed collection (genebank) of sweet potato in South Africa. The collection contains virtually all commercially grown cultivars, new improved varieties for African consumers and β-carotene rich varieties used in the crop-based approach to address vitamin A deficiency.  Due to yield loss by virus infection and other diseases, a disease-indexing scheme is currently operational at Roodeplaat in order to supply healthy planting material to the sweet potato industry.
