abstract = {In the coming decades, larger genetic gains in yield will
be necessary to meet projected demand, and this must be
achieved despite the destabilizing impacts of climate change
on crop production. The root systems of crops capture the
water and nutrients needed to support crop growth, and
improved root systems tailored to the challenges of specific
agricultural environments could improve climate resiliency.
Each component of root initiation, growth and development is
controlled genetically and responds to the environment,
which translates to a complex quantitative system to
navigate for the breeder, but also a world of opportunity
given the right tools. In this review, we argue that it is
important to know more about the ‘hidden half’ of crop
plants and hypothesize that crop improvement could be
further enhanced using approaches that directly target
selection for root system architecture. To explore these
issues, we focus predominantly on bread wheat (Triticum
aestivum L.), a staple crop that plays a major role in
underpinning global food security. We review the tools
available for root phenotyping under controlled and field
conditions and the use of these platforms alongside modern
genetics and genomics resources to dissect the genetic
architecture controlling the wheat root system. To
contextualize these advances for applied wheat breeding, we
explore questions surrounding which root system
architectures should be selected for, which agricultural
environments and genetic trait configurations of breeding
populations are these best suited to, and how might direct
selection for these root ideotypes be implemented in
practice.},
