Research Project: Seeds of Success (SOS) National Collection Initial Germination, Research, and Long-Term Storage with Curation

Location: Plant and Animal Genetic Resources Preservation

Project Number: 3012-21000-015-19-I
Project Type: Interagency Reimbursable Agreement

Start Date: Sep 1, 2016
End Date: Sep 30, 2020

To provide initial (pre-storage) germination data, long-term storage, curation, and viability testing of the Seeds of Success National Collection by the USDA, Agricultural Research Service (ARS), Plains Area (PA). The technical representative for the USDA, ARS, NPA responsible for the research will be the National Laboratory for Genetic Resources Preservation (NLGRP), Fort Collins, Colorado. The initial seed germination data and eventual viability testing of material in long-term storage provided by the NLGRP will allow the BLM and SOS to be more strategic in its seed collecting efforts to support the National Native Plant Materials Development Program and provide for long-term conservation storage of native plant genetic resources.

SOS partners will send about 3,000 quality cleaned seeds (with no seed treatment) for each SOS accession to the USDA-ARS-NLGRP for back-up storage and quality assessments. NLGRP will not distribute seed without written consent from BLM. Each sample shipped to NLGRP will have the SOS accession number clearly marked on the package. NLGRP will work with BLM, or other entity designated by BLM, to receive SOS accessions, facilitate information transfer on the sample being entered in the Germplasm Resource Information Network (GRIN) (or other database as applicable), adjust seed to moisture of about 25% RH, perform % viability (germination and/or TZ testing or % filled seed assays), seal the seed in storage bags and store the seed in the cold vaults (-18C) at the NLGRP. Periodically (on a 5 to 20 year time frame), the health of the seed will be monitored as resources allow. Timing of the monitor tests will be determined based on the species and the priorities of the SOS National Coordinating Office.
