Interpretive Summary: The Plant Genetic Resources Conservation Unit, Griffin, Georgia sends out seed packets of different crops to researchers all over the world. These scientists study the crops for different traits, however they do not often report back the results for each seed sample. Managers of germplasm collections need to encourage scientists to report back all their results, so that other scientists in the future will have more information available for each seed sample.

Technical Abstract: Since 1992, the Plant Genetic Resources Conservation Unit, Griffin, GA has distributed over 200,000 accessions to users throughout the world. The accessions are often evaluated for specific descriptors, disease or insect resistance, or other traits with conclusions published in journal articles. Complete data on all accessions evaluated would be useful to other researchers interested in the crop, however, users do not always submit data for entry in the Germplasm Resources Information Network (GRIN). This study quantified the number of distributions made for each crop maintained at Griffin in relation to evaluation data submitted by users for entry into GRIN. Since evaluations of few accessions would be of little value to researchers, all distributions of less than 25 accessions were not included. Data sets were submitted by users for GRIN entry for less than 5% of all distributions. Some of these data were submitted from ARS-funded evaluations in which data submission was required. Most data in GRIN was obtained from curators during seed regeneration or observations of accessions. Curators and seed bank managers must develop improved methods to encourage researchers to submit evaluation data of accessions into GRIN. This would improve the usefulness of germplasm collections and increase future research efficiency.
