Interpretive Summary: The National Center for Genetic Resources Preservation (NCGRP) has provided long term storage of back up seed samples for the Seeds of Success program since 2005. Between 2005 and 2014, NCGRP received about 8800 Seeds of Success (SOS) samples, representing over 700 species. In the process of testing SOS seed for viability and preparing samples for long term storage, seed quality challenges have emerged. These include the presence of inert and contaminants, dormancy issues, mechanical damage, and insect damage. Some wild-collected taxa produce high quality, low dormancy seed, while other taxa are more problematic.

Technical Abstract: The National Center for Genetic Resources Preservation (NCGRP) has provided long term storage of back up seed samples for the Seeds of Success program since 2005. Between 2005 and 2014, NCGRP received about 8800 Seeds of Success (SOS) samples, representing over 700 species. In the process of testing SOS seed for viability and preparing samples for long term storage, seed quality challenges have emerged. These include the presence of inert and contaminants, dormancy issues, mechanical damage, and insect damage. Some wild-collected taxa produce high quality, low dormancy seed, while other taxa are more problematic. Drawing on our observations within taxa, we’ll summarize taxon-specific trends in seed quality and dormancy.
