The Genetic Resources and Enhancement Unit (GREU) broke with tradition this week when instead of the usual seminar with a PowerPoint presentation it moved the talk to the screen houses at El Batán. Maria Zaharieva discussed a project dealing with phenotypic and taxonomic (physical characteristics and classification) characterization of wheat species and in particular wild relatives of wheat from the Wellhausen-Anderson Plant Genetic Resources Center. Her work also involves a Generation Challenge Program Project aimed at evaluating genetic diversity within these species. She showed participants the different species of wheat, how to identify them in the field, and indicated their value for bread and durum wheat breeding.
