Catalogue of Native Potatoes


This catalogue provides information about Peruvian potato landraces resistant to potato late blight. These landraces are kept in custody at the International Potato Center (CIP), and.are available for distribution in Peru to potato research programs and other interested parties, including national programs, universities, producers’ associations and farmers’ communities. Information for each landrace includes morphological characters of the tubers, and the level of resistance to potato leafroll virus (PLRV), root knot nematode (Meloidogyne spp.) and late blight (Phytophthora infestans). These landraces are used routinely by farmers in the highlands of Peru and, since they are resistant to late blight, are particularly suitable for locations or planting dates with high rainfall.

How to use this catalogue

This catalog is designed so that users can access information in two ways: by the common name or the accession number.

How to order

If you are interested in ordering landraces you have to "click" on the cart that appears on the page of each landrace. Next you should complete the information requested and submit the form as indicated. CIP’s Germplasm Acquisition and Distribution Unit (ADU) will contact you to coordinate the management of all necessary documentation for the shipment of your order.


This research was undertaken as part of the CGIAR Research Program on Roots, Tubers and Bananas (RTB) and the CGIAR Genebank Platform. Funding support for this work was provided by the OPEC Fund for International Development (OFID), project 1357 (Screening for resistance to late blight in Peruvian wild potato species and traditional landraces: A key contribution to improve farmers’ livelihoods in Peru and globally) and the CGIAR Genebank Platform.

In the catalogue itself:

Susceptibility scale value to late blight*: 2.04

*Mean value of 8 to 15 plants. The susceptibility scale described by Yuen and Forbes (2009, Phytopathology 99:782-786) presents ascending values corresponding to increasing susceptibility to the disease. Lower values mean less susceptibility (“resistant”) and higher values mean more susceptibility (“susceptible”). As reference, cultivars “Chucmarina” and “Pallay Poncho” have susceptibility values less than 3 and are considered resistant, while “Yungay” has a value more than 6 and is considered susceptible.
