A small-scale assessment of the availability of EURISCO accessions

A critical assessment of plant genetic resource (PGR) availability in Europe reveals a significant gap between documented accessions and those that are practically obtainable for researchers and breeders. While the EURISCO database lists over two million accessions, a study of 100 random accessions found nearly 60% to be unavailable, challenging the assumption that a large number of documented accessions equals usability. Material from 52% of the approached genebanks could not be obtained within five months. The primary barrier was the inability to contact genebank staff, which points to a systemic issue in which PGR access is not always prioritized. Insufficient material for distribution and geopolitical issues were further causes of low availability. This indicates a threat to the effective utilization of European PGR and highlights an urgent need for genebanks to improve communication and operational capacity to ensure these vital resources become accessible for crop development and food security.
