Abstract:

Lean phenotyping: Plant phenotyping plays a crucial part in the development of new crop genotypes. Driven by the availability of new digital sensors, digital phenotyping methods have been developed in recent years with the aim to make plant breeding and variety testing more efficient, more objective and/or more precise. Many of these methods have not yet made their way to the fields of variety testing or breeding oganizations as they often rely on custom-made expensive devices and sophisticated workflows. In order to make the advantages of digital phenotyping accessible to variety testing, these methods must be simplified and adapted so that they can produce measurements of good quality with simple devices. In addition, simplified methods are more easily scaled up to deal with genotype-by-environmentinteractions in multi-environment trials than dedicated phenotyping platforms. In the two projects presented here, the applicability of relatively simple commercially available digital phenotyping devices was tested and improved in the context of wheat variety testing.
