Germplasm Characterisation - banks contain enormous amounts of germplasm, which is only partially characterised. For established commercial cultivars that are typically characterised in detail according to international rules, much data is usually available, at least in non-digital form. For older land races or cultivars only used locally, the amount of available information is as a rule extremely limited. Nevertheless, even for established cultivars quantitative and especially dynamic digital data obtained under controlled or specific stress conditions is seldom available. Such data would be an extremely valuable aid in searching for plants with interesting traits or genes, as well as in saving the access to local (national or regional) germplasm by providing sufficient information for functional patenting and community plant variety rights.
As seeds are highly valued and only rarely available for germplasm characterisation LemnaTec scanalyzer systems can help to provide a maximum of digitised phenotypic data on plants and seeds
Contribution of LemnaTec scanalyzer3D plant phenotyping systems to germplasm characterisation
Germplasm Characterisation: Phenotyping large amounts of cultivars in germplasm banks and seed collections aided by the non-destructive, automated, image-based LemnaTec scanalyzer technology generates an enormous amount of information for the efficient and searchable digital characterisation of crops. It can be performed during routine, periodical seed production to keep a high degree of quality and viability in the stored seeds. Comprehensive digital documentation of the full life cycle allows a more thorough exploitation of existing cultivars. In addition, characterisation under stress conditions that are highly controlled, with LemnaTec watering and nutrient dosage systems (waterlogging, drought, water usage efficiency, nutrients) is very suitable for testing individual plants. Such stress testing of large numbers of valuable plants in a highly automated way is possible with LemnaTec scanalyzer3D conveyor systems for greenhouses and growth chambers. In many cases these systems will provide at least hints of new, unanticipated traits never tested before in (drought or resistance tests). Additionally, the extensive documentation and the chance to characterise plants objectively allows saving their value by patenting or publishing the results, thus avoiding exclusive patenting in cases where germplasm should be saved as a common heritage.
