“…This informed the next major element of the program, namely virology research and the provision of virus‐indexed planting material. Since the 1970s, the ARC has run a sweet potato disease‐indexing scheme, which annually provides healthy mother planting material to the sweet potato industry (Laurie et al., 2016). In addition, the polycross system was adopted in the 1980s as illustrated by Bester and Louw (1992) to improve crossing efficiency and extensive cultivar evaluation trials were conducted focused on the commercial sector, which resulted in the release of the widely used cultivar Blesbok in 1989 (Bester et al., 1991).…”

The 2030 Agenda for Sustainable Development Goals (SDG) of the United Nations puts forward a transformational vision to cope with food security, nutrition and health challenges, in which sweetpotato can play an important role. Globally sweetpotato production is valued at US$53.83 billion. The ARC sweetpotato research and development (R&D) program over the past seven decades delivered 31 genetically improved cultivars via demand‐led breeding, managed the collection and maintenance of 375 accessions, contributed towards the optimization of cultivation practices, developed crop protection and diagnostic services, provided stream‐lined seed systems and technology transfer in processing and enterprise development. The ARC's work is part of a large number of interdependent global programs committed to improving livelihoods and nutrition through sweetpotato. This review shares and analyses major achievements, highlights unique research contributions achieved through partnerships and discusses bottlenecks on funding and up‐take of technologies. New research imperatives will involve root phenotyping, employing marker‐based technologies and genome‐wide association studies through new funding received recently. Exploration of the commercialization potential of processed products made from orange‐fleshed sweetpotato will be a major focus of the R&D program. Expansion of partnerships, marketing and financing will be important for future contribution of sweetpotato to the economy.This article is protected by copyright. All rights reserved

“…Virus-tested stock plants are produced by the sweet potato scheme at the Agricultural Research Council-Vegetable and Ornamental Plants (ARC-VOP) (Laurie et al, 2016) and serve as a source of healthy vines for multiplication by vine growers, who are then responsible for supplying healthy planting material to sweet potato producers. Sweet potato vines are also affected by frost, which in turn affect the availability of planting material per location per period of time (Allemann et al, 2004).…”

Sweet potatoes present an opportunity for improving food security and income generation in South Africa. The yield of sweet potatoes is highly dependent on the quality of sweet vines used in production. This study aimed at identifying the most cost effective and best storage bag type, between polyethylene and hessian bags, to prolong vine storage. Three bag treatments namely polyethylene bag without holes, polyethylene bag with 12 holes and dry hessian with vines from sweet potato cultivar "Bophelo" were stored for 3, 6, 9, 12 and 15 days at ambient temperature during summer. The costs effectiveness of using different types of bags when transporting and storing vines was calculated using the incremental cost-effectiveness ratio (ICER). The results of the study showed that hessian bags offer the best option to prolong storage (12 days) as compared to polyethylene bags (6 days), however hessian bags are more expensive (R49.10/1 day quality) ($4.08 as at 24/01/2018). Polyethylene bags can be used if the farmer is not willing to pay the additional cost for an addition day of quality. Holes need to be made in polyethylene bags in order to allow air circulation.
