Standard descriptors and EURISCO development

The paper gives information about both the genesis, and a survey of, the descriptors used for the documentation of plant genetic resources held in ex situ crop collections. The first international documentation standards were developed by the FAO in the 1950s. In 1974, a specific body for plant genetic resources, the IBPGR (International Board for Plant Genetic Resources), was established within the FAO. Since the 1970s, the descriptor lists for main crop collections have been developed, including passport descriptor sets. For the most part, the passport descriptors were common to all crops, with only slight differences. In 1997, the first attempt to create a standard set of descriptors resulted in 24 passport descriptors developed by FAO and IPGRI (International Plant Genetic Resources Institute) working in cooperation. In 2001, the official Multi-Crop Passport Descriptor list (MCPD) was published, including a revised standard set of 28 descriptors. The European ex situ crop catalogue (EURISCO) enlarged the standard set of passport descriptors by adding 6 additional fields in 2002; and another 2 new descriptors were added in November of 2008. A global level of data compatibility is preferred; therefore projects aimed at world-wide utilization and standardization of systems, such as GRINGlobal, and Accession-Level Information System (ALIS), are supported.
