Sweetpotato and potato are expanding faster than any other food crops in sub-Saharan Africa. There is growing investment in research to address bottlenecks in value chains concerning these two crops, and growing interest from the private sector in investing in them. This book addresses five major themes on sweetpotato and potato: policies for germplasm exchange, food security and trade in Africa; seed systems; breeding and disease management; post-harvest management, processing technologies and marketing systems; nutritional value and changing behaviours.
1. Advances in sweetpotato breeding from 1992 to 2012
2. Breeding sweetpotato for yield and beta-carotene content in Burkina Faso
3. Development of dual-purpose sweetpotato varieties through participatory breeding in Rwanda
4. Development and evaluation of new sweetpotato varieties through farmer participatory breeding for high altitudes in Kenya
5. In vitro evaluation of orange-fleshed sweetpotato for drought tolerance using polyethylene glycol
6. Ex-ante evaluation of improved potato varieties for sub-Saharan Africa
7. Durable cisgenic resistance to phytophthora infestans in potato and perspectives for applications in Africa
8. Exhibition trial and farmer participatory selection of new late blight resistant b3c1 potato genotypes for adaptation to Nigerian conditions
