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.

ELISA tests were conduced for APMoV, PLRV, PMTV, PVY and PVX.

The present guide is designed to assist professionals and technicians in charge of evaluation trials designed to screen selected potato genotypes for resistance to this disease. The evaluation of breeding families, which is carried out under greenhouse or field conditions, can use the same methodology. The guide can help to organize trials, improve data collection and analysis and introduces new criteria for resistance measurement based on epidemiological principles.
