Strategies to increase yield and yield stability of crops under drought – are we making progress?

Abstract

The objective of the InterDrought conferences is to serve as a platform for presenting and debating key issues and strategies relevant for increasing the yield and yield stability of crops under drought conditions by the use of integrated approaches. InterDrought-IV held in Perth Australia in September 2013 followed the practice of previous InterDrought conferences of bringing together in one room research scientists and students in agronomy, soil science, modelling, physiology, biochemistry, molecular biology, genetics and plant breeding. Key themes were (i) maximising water productivity, (ii) maximising dryland crop production, (iii) adaptation to water-limited environments, (iv) plant productivity under drought through effective capture of water, improved transpiration efficiency and growth and yield, and (v) breeding for water-limited environments through variety development and trait-based, genomics-assisted and transgenic approaches. This paper highlights some of the key issues and presents recommendations for future action. Improved agronomic interventions were recognised as important contributors to improved yields of dryland crops in water-limited environments, while new methods for the rapid exploration of root architecture and water capture were highlighted. The steady increase in the yield of crops under drought through breeding and selection, the development of high through-put phenotyping facilities for plants in pots and in the field, and the advances made in recent years in dissecting and understanding the molecular basis of plant responses and plant resistance to drought stress were recognised in the presentations and discussions. Managed-environment phenotyping facilities, a range of field environments, genomics and molecular tools, and modelling are being used to select and release drought-resistant cultivars of all major crops. The delegates discussed how individuals.
