Page scope

National Plant Germplasm System is about the gene bank network of the United States Department of Agriculture: its sites and stores, the cannabis it has received since 1898, the hemp collection at Geneva, New York, and the terms on which it supplies seed. Cannabis lots it holds that have their own accession pages are listed at the foot of the article.

Sourcing

The figures for cannabis come from the system's own database, GRIN-Global, as it stood on 6 November 2026, and from the pages of single accessions. The sites, stores and terms of supply come from the pages of the Agricultural Research Service and GRIN-Global, the 2024 factsheet of Cornell University on the hemp collection and the SMTA notice of 30 December 2024. The history of the Fort Collins laboratory comes from Helen Anne Curry (2022). Discuss sourcing and any figure that has changed here.

Totals for the whole system

The pages of the Agricultural Research Service give different totals. The Fort Collins plant science page (February 2026) gives more than 621,000 plant accessions of over 16,800 species at more than 20 sites. The Geneva hemp page (January 2025) gives over 600,000 accessions, and the Fort Collins unit page more than 500,000 accessions held at Fort Collins itself.

PI 948 and PI 957

The two entries carry the same received date, origin, collector, comment ("From Nertchinsk, Siberia") and exploration identifier, NEH1897. Whether they were two lots or one lot entered twice is not settled by the database.

Historic entries received since 2022

Seven of the 159 historic entries, cultivars from France and three clones from the United States, were received in 2022 and 2023. The database gives no reason for their historic status.

Free of charge

The distribution policy names no fee. The statement that seed goes free of charge to research projects anywhere in the world is the Cornell factsheet's.
