Descriptors

Using the Descriptor menu option, you can find germplasm based on their recorded observations. Note that not all accessions in the collection may have recorded observation records; descriptor searches do not ensure that every accession in the crop is being searched.

In GRIN-Global, a "Crop" is loosely defined as a collection of taxa, as decided by the curator. In some cases, the Crop may have further divisions, to meet specific needs. For example, in the USDA’s NPGS GG database, Vitis vinifera accessions are maintained at two different NPGS sites and are organized under two different crops. 

Not sure what crop to select? Use the Reports option; enter  genus and the report will indicate the crop(s).   As an example, in the NPGS GRIN-Global database, Vitis, Vitis vinifera, and Vit% all will find two "GRAPE" crops: Why two grape crops? They did this to differentiate the locations where the collections are maintained - one collection is in Geneva, New York, and the other in Davis, California.
