Global Strategy for the Ex Situ Conservation of Potato - Global Crop ...

Digitalisation of passport data and morphological descriptions currently available on
cards or other formats; the VIR morphological information would need codification
before digitalisation.
Validation of morphological descriptors on field collections of collections included in the
project by the use of CIP minimum standard descriptors (most used and most
stable). Current descriptor list needs to be translated into English before it can be
used and distributed. Exchange of information electronically.
Carry out first comparative exercise using the electronic passport and morphological
data. Exchange of the resulting analysis electronically.
Extract DNA from the accessions (we estimate 1000 accessions organized into
morphological groups). Send DNA samples to CIP for molecular analysis.
Carry out the molecular analysis using SSR markers available at CIP. Work to be
conducted mainly at CIP.
Final identification of genetic duplicates using the passport, morphological and molecular
data.
A workshop should be held at CIP before the project is implemented to discuss and
agree on methodologies and procedures.

4. Regeneration needs
Title: Regeneration of endangered potato accessions
Implementing /coordinating institutes: INTA will coordinate this proposal
• Focal person: Andrea Clausen (INTA, Argentina)
• Task force: Andrea Clausen (INTA, Argentina), Alvaro Monteros (DENAREF, Ecuador)
Gavin Ramsay (CPC, UK), Stepan Kiru (VIR, Russia)
Partners: Argentina (INTA), Bolivia (PROINPA), Chile (UACH), Colombia (CORPOICA),
Ecuador (DENAREF/ INIAP), CIP (Peru) for use of the databases, Russia (VIR) and others
Time frame: 3-5 years
Objective: To safeguard unique potato genetic resources which need urgent regeneration
Process and activities:
1) Identify unique material which has a high priority for regeneration; the participating
collections can produce these priority lists from their collections.
2) The overall priority of the selected accessions should be clarified by comparing with
the international databases.
3) Both wild relatives and vegetatively propagated potato species will be included
4) Gene bank management and facilities need to be improved in some gene banks
(capacity building).
5) The questionnaire estimated that in the participating genebanks 2,000 accessions of
wild species and 2,200 accessions of native cultivars from the centre of origin
approximately need urgent regeneration. Considering that the duplication rate is
approximately 50% between these collections it would mean that 1,000 accessions of
wild species and 1,100 accessions of native cultivars need to be urgently
regenerated.
6) The regeneration should be followed by safety duplication, applying the black box
principles.
7) The regeneration should also consider the health aspects of the material.
