In a nutshell
The properties of a breeding plant in the field are examined. We do this by using modern technologies for automated analysis.
This method is non-invasive and does not affect plant development. Digital phenotyping, for example, allows us to draw conclusions about infestations with fungi.
The challenge this method poses is that the “correct aspect” has to be measured. Only once we know which genetic mechanism causes a specific change in the appearance of plants can we develop automatic recognition through sensors. We must also be able to quickly analyze large quantities of data, which requires broadband data lines to the breeding stations.
The distinction between genotype and phenotype dates back to Wilhelm Johannsen (1911). A genotype is the sum of the properties inherited from parents. The phenotype of a plant is defined accordingly, but also modified in accordance with environmental conditions. We propose that: A genotype is the sum of all genetic characteristics of an organism, such as a plant. The phenotype of this plant is created as it grows under the environmental conditions present.
