Why it matters
An accession identifier connects material to its origin and management records. Keeping that connection intact helps custodians distinguish what they hold, what has been distributed, and what a duplicate is intended to preserve.
A practical example
Imagine a genebank sends part of a seed accession to another facility. The receiving facility needs the associated identity and records so the material can be traced back to the same collection entry.
An important distinction
An accession is not necessarily a single genotype or a unique variety. Its composition depends on the material and how it was collected. Counting accessions alone does not measure all the genetic diversity preserved.
