An increasing interest in the study and use of wild relatives of crop plants has led to considerable collecting of such material. In the case of wild Triticum L. spp. and Aegilops L. spp. a large number of accessions have been collected from throughout the area of occurrence of the two genera. The resulting collections are dispersed among many institutions throughout the world. In order to evaluate the completeness of previous collecting, target future collecting more precisely, and improve utilization of the material, IBPGR in collaboration with ICARDA has compiled a database containing passport data on 14872 accessions originating from 33 countries currently held in over 50 genetic resources collections. This database provides information on the existing status of Aegilops and wild Triticum collections, which can be used to identify duplicates, map the distribution of collected materials of the species, and identify accessions collected from specific stressful environments. By comparing the information on individual species with a herbarium database of 2167 records and with other information on the species, the extent to which past collecting has sampled the gene pools of the two species can also be evaluated.
