To achieve food security, quick investments in crop improvement are required to increase their resistance for both biotic and abiotic threats while sustaining high-quality and optimal yields and this is the gap to be addressed by the concept of speed breeding. From carbon arc to LED lamp, the journey of speed breeding is empowered by the tools of plant physiological factors such as photosynthesis, respiration, flowering and crop phenology. The modifications in environmental growth factors not only allow reducing the seed to seed time interval but also combining with high throughput phenotyping, genome editing and transgenic pipelines. This literature is mainly focusing on the driving energy of speed breeding exploiting from the plant physiological phenomena.
