Abstract

Potato (Solanum tuberosum L.) is one of the major crops in Africa with the potential of improving food and nutritional security. Potato cyst nematodes (PCN), Globodera pallida and G. rostochiensis have more recently been reported as a new pest challenging production of the crop in the region. This review analyses development and selection of PCN resistant cultivars in Africa as a PCN control strategy with major focus on sources of host resistance in existing cultivars. A limited number of studies on development and selection of PCN resistant cultivars were found. Despite this, there were multiple PCN resistances particularly among cultivars originally sourced from Europe and grown by farmers in the region. This review proposed identification and utilization of resistant cultivars already adopted by farmers as an immediate strategy for PCN control while waiting for the development of new resistant cultivars as a long-term solution to the problem.

期刊介绍： The American Journal of Potato Research (AJPR), the journal of the Potato Association of America (PAA), publishes reports of basic and applied research on the potato, Solanum spp. It presents authoritative coverage of new scientific developments in potato science, including biotechnology, breeding and genetics, crop management, disease and pest research, economics and marketing, nutrition, physiology, and post-harvest handling and quality. Recognized internationally by contributors and readership, it promotes the exchange of information on all aspects of this fast-evolving global industry.
