Peru

International Potato Center (CIP)

Peru
CIP is an International Agricultural Research Organization. Our vision is roots and tubers improving the lives of the poor.

Missions

The mission of CIP is to work with partners to achieve food security, well-being, and gender equity for poor people in root and tuber farming and food systems in the developing world. We do this through research and innovation in science, technology, and capacity strengthening.

We study viruses of potato, sweetpotato and other Andean root and tuber crops in Peru and worldwide, but also conduct research into virus resistance, bacterial wilt of potato and late blight, develop novel diagnostic methods, and tools for surveillance and risk assessment.

 

Current projects

  • The Peruvian potato virome
  • The virome of other Andean root and tuber crops
  • Improved diagnostic tools for sweetpotato virus detection
  • Next generation phytosanitation : rapid detection and elimination of viruses from root and tuber crops
  • Improved Diagnostics and Genotypic/Epidemiological Mapping Potato Bacterial Wilt Disease in East Africa
  • Quorum quenching for enhanced resistance to bacterial wilt disease
  • Virus transmission models for emerging viruses and forecasting in the face of climate change
