随着作物产量越来越接近生物物理极限，实现产量增加变得越来越具有挑战性，需要更多地了解产量的确定性途径。在这里，我们提出了一个接线图作为一个平台，以说明影响小麦产量潜力的生理性状的相互关系，并作为作物科学家的决策支持工具。线路图是基于这样一个前提，即作物产量是光合作用（源），同化物投资到生殖器官（汇）和基本过程，使两者的表达功能。通过将这些联系描述为编码线，接线图可以显示可能不明显的性状之间的联系，并可以为新的研究假设提供信息，并指导旨在积累育种中有益性状和等位基因的杂交。接线图还可以为将来改进作物模型创建更丰富的公共参考点。
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.
