Why Gap Analysis?
• CG collections suffer from both over- and under- collecting
• Duplications increase costs
• But also significant gaps in the collections
Why Gap Analysis?
• Tool to assess crop genetic and geographical diversity.
• Allows detecting non-fulfilled species collections as well as defining which species should be collected and wherethese collections should be focused.
• Assesses the current extent at which the ex situ conservation system is correctly holding the genetic diversity of a particular genepool.

The Rugosi and Acutifolii case
• Section Acutifolii– P. acutifolius– P. acutifolius var. acutifolius– P. acutifolius var. latifolius– P. acutifolius var. tenuifolius– P. parvifolius
• Section Rugosi– P. angustissimus– P. filiformis– P. carteri

Are there analyses for other crops?
� 13 crop genepools analyzed, 7 analyses in the pipeline� Recommendations on which taxa are priority to conserve� Maps indicating what and where to collect� Results publicly available at: http://gisweb.ciat.cgiar.org/GapAnalysis/
