Most of the evaluation data are the result of screenings of the germplasm by potato specialists at different institutes in the Netherlands and Germany. Furthermore, some data from liturature reports and screenings at private breeding companies have been included.
Evaluation results are available on diseases and some quality traits: root-knot and cyst-nematodes, late blight, wart, gangreen, dry rot, potato viruses M, X and Y, blackleg, softrot, dry weight, reducing sugar and vitamin C contents. The results must always be considered as preliminary.
Additional info is available on: I) evaluation methods and II) other sources with evaluation results on glycoalkaloids, nitrogen uptake and use efficiency, starch & amylose content and size & morphology of starch granules, protein content, Potato tuber moth, late blight. The Portal provides links per trait to on-line available evaluation data for potato germplasm in different collections.
Users of CGN germplasm are requested to share their evaluation data on the received accessions. An embargo period before including the results in the database of CGN can be agreed upon.
