The International Maize and Wheat Improvement Center (CIMMYT) and the University of Queensland organised Interdrought 2020, an international congress aiming to facilitate the development of concepts, methods and technologies associated with plant production in water-limited environments. Its themes included plant production under drought, and breeding for water-limited environments. The meeting was due to take place on 9-13 March 2020 in Mexico City but was cancelled because of the COVID-19 pandemic. The organisers, however, have made all the presentations, abstracts and posters available. See https://interdrought2020.cimmyt.org/ or contact [email protected] for more information. This is the 6th Interdrought congress – the first one took place in Montpellier in 1995.
