The European Dactylis Database is maintained by the Botanical Garden of Plant Breeding & Acclimatization Institute (IHAR) which holds the national grass collection in Poland. This database contains passport data on 8700 accessions of 10 taxa stored in 23 European genebanks. The database includes cultivars and breeder’s lines (587 accessions), primitive cultivars and landraces (149), natural and seminatural ecotypes (7789). Two percent of all accessions (i.e. 175) are unnamed and with unrecorded status. Seed requests should be sent to holding institutions.
