A validated slow-growth in vitro conservation protocol for globe artichoke germplasm: A cost-effective tool to preserve from wild to elite genotypes

•A genotype-independent protocol for artichoke germplasm conservation is proposed.•The protocol was validated by a field test using approved descriptors for artichoke.•The protocol responds adequately to the need coming from commercial laboratories.•This protocol helps to preserve globe artichoke biodiversity.•This protocol saves both time and money and is highly efficient.
