Crop production provides food, feed, and fiber for our society. To keep the yields high and to adapt to stresses as well as to the impacts of climate change, plant breeders continuously generate new genetic variations of crops. These variations are then planted, and their performance is assessed. For that, plant breeders are looking for effective systems to assess detailed phenotypic traits about plants at a large scale for an in-depth understanding of the relationship between genotype and phenotype. Recording how the individual plants develop and grow is a labor- and time-consuming process.
