Potato virus Y (PVY) is causing yield and quality losses forcing farmers to renew periodically their seeds from clean stocks. Two loci for extreme resistance to PVY, one on chromosome XI and the other on XII, have been identified and used in breeding. The latter corresponds to a well-known source...

Potatoes have become increasingly popular amongst Chinese consumers, and the water saving and storage capacity of the crop have made it a target of Government promotions. Potato production is a means of generating income as well as improving food and water security. Getting the right varieties to...

Biotic constraints cause major crop losses and, hence, food insecurity in sub-Saharan Africa. This study documented the popularity, production constraints, pests and diseases, farmers’ perceptions on the severity of biotic constraints and the impact of related crop losses on household food securi...

This report presents the results of the Participatory Varietal Selection (PVSs) implemented in 2018. A total of 116 people participated in the PVSs at the flowering stage and 139 people participated at the harvesting stages. Gender‐responsive approaches were employed to facilitate women’s active ...
