Since 2010 CGN has built a black salsify collection and this started with the acquisition of the accessions available in European genebanks and working collections of several companies.
This resulted in the acquisition of 15 Dutch varieties, seven varieties from Belgium and some other varieties from various Eastern European countries. In 2014 and 2015 a few accessions of Scorzonera humilis and Tragopogon porrifolius ssp. porrifolius were also collected in the Netherlands. After successful regeneration, the material will become publicly available. All together the collection currently consists of 30 accessions and it is expected that in the near future another five-ten accessions will be added to the collection.
