Autor: Bentley, J.W. Andrade-Piedra, J.L. Demo, P. Dzomeku, B.M. Jacobsen, K. Kikulwe, E. Kromann, P. Kumar, L. McEwan, M. Mudege, Netsayi N. Ogero, K. Okechugwu, R. Orrego, R. Ospina, B. Sperling, L. Walsh, S. Thiele, Graham

Vegetatively propagated crop (VPC) seed tends to remain true to varietal type but is bulky, often carries disease, and is slow to produce. So VPC seed needs to be handled differently than that of other crops, e.g., it tends to be sourced locally, often must be fresh, and it is less often sold on ...

Epidemic network analysis for mitigation of invasive pathogens in seed systems: potato in Ecuador

Autor: Buddenhagen, C. Hernández Nopsa, J.F. Andersen, Kelsey F. Andrade-Piedra, J.L. Forbes, G. Kromann, P. Thomas-Sharma, Sara Useche, Pilar Garrett, K.A.

Seed systems have an important role in the distribution of high-quality seed and improved varieties. The structure of seed networks also helps to determine the epidemiological risk for seedborne disease. We present a new approach for evaluating the epidemiological role of nodes in seed networks, ...

Potato crop health quality and yield losses in Ecuador

Autor: Navarrete, I. Panchi, N. Andrade-Piedra, J.L.

The poor knowledge about the presence of diseases and pests affecting the potato crop in developing countries difficult the understanding of their distribution in agro-ecological systems and consequent effect on yield and seed quality. A combination of a monitoring and a field experiment were per...

Potato seed systems.

Autor: Forbes, G. Charkowski A Andrade-Piedra, J.L. Parker, M. Schulte-Geldermann, Elmar

Good quality seed is almost universally considered a requirement for high productivity in all potato production systems. Much of the yield gap currently constraining productivity in low-income countries is attributed to the poor quality of seed. Potato seed sector development is thus a major conc...
