Garrett, K.A.Forbes, G.Savary, S.Skelsey, P.Sparks, Adam H.Valdivia, C.Bruggen, A.H.C. vanWillocquet, L.Djurle, A.Duveiller, E.Eckersten, H.Pande, S.Vera Cruz, C.Yuen, J.[Complexity in climate-change impacts: an analytical framework for effects mediated by plant disease.]Complexity in climate-change impacts: an analytical framework for effects mediated by plant disease.

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...


Herrera, M.R.Jara Vidalon, L.Montenegro, J.D.Riccio, C.Guzmán, F.Bartolini, I.Ghislain, M.[Molecular and genetic characterization of the Ry adg locus on chromosome XI from Andigena potatoes conferring extreme resistance to potato virus Y.]Molecular and genetic characterization of the Ry adg locus on chromosome XI from Andigena potatoes conferring extreme resistance to potato virus Y.

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 paper evaluates the determinants of decision-making in relation to the production of four crops (banana, cassava, potato, and sweet potato). Understanding the division of labor and decision-making in crop management may lead to designing better interventions targeted at improving efficiency ...
