This article proposes the use of a wiring diagram as a platform to illustrate the interrelationships of physiological traits that impact wheat yield potential and guide breeding decisions. The wiring diagram serves as a tool to reveal connections among traits and informs new research hypotheses.
As crop yields are pushed closer to biophysical limits, achieving yield gains becomes increasingly challenging and will require more insight into deterministic pathways to yields. Here, we propose a wiring diagram as a platform to illustrate the interrelationships of the physiological traits that impact wheat yield potential and to serve as a decision support tool for crop scientists. The wiring diagram is based on the premise that crop yield is a function of photosynthesis (source), the investment of assimilates into reproductive organs (sinks) and the underlying processes that enable expression of both. By illustrating these linkages as coded wires, the wiring diagram can show connections among traits that may not have been apparent, and can inform new research hypotheses and guide crosses designed to accumulate beneficial traits and alleles in breeding. The wiring diagram can also serve to create an ever-richer common point of reference for refining crop models in the future. Achieving yield gains requires more insights into the deterministic pathways of crop yields. This Perspective proposes a wiring diagram as a platform to integrate knowledge of the interrelationships of physiological traits impacting wheat yield potentials and their interactions with the crop developmental stages that can be used to accelerate genetic gains through breeding.
