The caraway collection originates from the former Centre for Plant Breeding and Reproduction Research (CPRO), in Wageningen. It was a sleeping collection till 2012 when it was revived in the framework of CGNs initiative to profile as a vegetable genebank. The collection was rationalized excluding cultivars with breeding rights and some wild accessions collected on relatively short distance in Bavaria 1994. Currently 20 Carum carvi accessions are available for distribution.
Regeneration occurs in field plots with 80 – 120 plants. The seeds are sown at the end of July and plantlets transferred to the field in September. Caraway is a biennial crop. The plants need a period of low temperatures to induce flowering (vernalization). The seeds are harvested in the second half of July in several rounds, because flowering and seed ripening is stretched over several weeks. Between the isolation plots an distance of at least 100 m. is required, but a larger distance of 300 – 700 m. has been practiced.
