The idea of breeding drought tolerance has been around for a long time, but we still haven’t been very successful. Perhaps one reason is that drought tolerance is not dependent on a single trait, but on many traits that all interact. This presentation will discuss how we can integrate phenotyping and modelling approaches in order to identify the multi-trait combinations, or “trait syndromes”, that have the potential to increase drought tolerance. The talk will introduce the hydraulic traits that contribute to drought tolerance, discuss their genetic diversity and environmental plasticity, and finally explore their sometimes emergent and unpredictable interactions that result in drought tolerance. The diversity of drought tolerant trait syndromes we have identified helps explain the hierarchy of drought tolerance observed across traditional varieties while at the same time pointing the way to the development of even more drought tolerant genotypes in the future.
