Bread wheat landrace diversity in the CGIAR collections:Complementarity of CIMMYT and ICARDA

Accessions conserved at CIMMYT and ICARDA were mapped onto the end-groups

in the tree and against crop suitability area on the map (FAO/IIASA 2011).

97% of the 62 end-groups in the Bread Wheat Diversity Tree are represented in CGIAR

collections. 84% are well represented or have a fair representation. 50% of the groups that have no or poor representation at CIMMYT have at least a fair representation in ICARDA collections.

The Bread Wheat Diversity Tree is a representation of the structure of the bread

wheat genepool obtained by dividing it into hierarchical clusters (Van Treuren et al. 2009).
