EuroBlight Workshop 15-17 May 2017– Aarhus, Denmark

Current situation and future of CIP’s role in regional potato late blight networks

Jorge Andrade-Piedra Greg Forbes

Outline

• CIP’s mandate and structure • Some history: GILB, Euroblight (Arras) and

Bellagio meetings • Current activities: Asia, Africa, South America • Looking forward – Partnerships with private

companies: fungicides, host resistance, LB management

CIPs Strategy and Corporate plan 2014-2023: six programs

Development oriented: impact in the next 5-10 years

Game Changing Solutions

Research oriented: impact in the long term: 20-30 years Resilient

Nutritious Sweetpotato

Agile Potato for Asia

Potato Seed for Africa

Resilient Food Systems

Conserving Diversity for the Future

3 International meetings: Ecuador 1999, Hamburg 2002, China 2008 8 regional meetings: PE, NL, IL, US, BO, KR, CN, MM 480 members from 72 countries

Bellagio 2009, Arras 2010 From GILB to Global EuroBlight

Use of Euroblight model in the developing world • Pathogen monitoring

– Not much for DSS adjustment, but for explaining and anticipating durability of resistance, fungicide use, etc.

• Data management – Protocol standardization – Data bases

• Social capital and collaboration

Priority countries

Initial AsiaBlight project: a coarse-scale map of the current late blight population in Asia

Blue: sent/received Green: not sent

Sampled for AsiaBlight * Sampled and genotyped by other projects Not sampled for AsiaBlight Louise Cooke

KE-1 = 2_A1

Red KE-1 (Potato) Blue US-1 (Potato) Cyan US-1 (Tomato)

Displacement of US-1 by KE-1 in Africa

• Mid 2014: no KE-1 in sw-UG

• End 2014: KE-1 in sw-UG

• 2015-2016: KE-1 in BI, RW, TZ

In summary

CIP’s role in LB R&D: • Pathogen studies • Breeding populations and resistant varieties • Decision support systems for farmers • Support to regional Blight networks So, what is next?

Asia, Africa, Latin Blight

• Alliances with private companies • Contacts at country level, but not at regional

level (except in Asia) • Potential areas of collaboration

– Pathogen studies – Fungicide testing – Dissemination of resistant cultivars – Validation of DSSs and training

The International Potato Center (known by its Spanish acronym CIP) is a research-for-

development organization with a focus on potato, sweetpotato, and Andean roots and tubers. CIP is

dedicated to delivering sustainable science-based solutions to the pressing world issues of hunger,

poverty, gender equity, climate change and the preservation of our Earth’s fragile biodiversity and

natural resources.
