Perform ecogeographic characterizations of the georeferenced collecting sites
• Is your collection representative of the species’ environmental adaptive range?
Check the ecogeographical representativeness of your ex situ collection

Evaluation of the ecogeographicalrepresentativeness of the germplasm collections
• Ocurrence of the highest levels of diversity in terms of average genotypic, phenotypic or ecogeographic distances among local
Identify where is located the diversity hotspots using phenotypic, genotypic or ecogeographic data

Waterlogging tolerance
Generation of subsets of breeding interest traits based on ecogeographic conditions of the collecting sites (Focused Identification Germplasm Strategy – filtering method)
CAPFITOGEN tools offer:
• Avoiding collecting in sites where other have been collecting in past expeditions
• Collecting germplasm in under or non-represented environments
• Collecting germplasm in sites with high probably of traits of interest occurrence
