Abstract only
In order to breed the crop plants required for the future, the efficient use of genetic resources is essential. During the last decades thousands of Triticum and Aegilops accessions have been collected and stored in various genetic resources centers. An accurate documentation of this conserved germplasm is critical for its effective management and utilization. In the present study, morphological and genomic descriptive information was collected from 150 accessions of different wheat relatives held in the CIMMYT Gene Bank, and part of the wheat composite collection of Generation Challenge Programme. These accessions were assembled in an herbarium of dried plant specimens and in a virtual (photographic) herbarium, providing support for taxonomic documentation. All this information, along with passport data, guarantees a quality control from the genebank accession to the genotyping data. It can also be used to develop a well-documented set of wheat relatives to be further phenotyped, enabling plant breeders to make decisions regarding the material to be used in wheat improvement programmes.
