- germplasm_heterotic_group: The germplasm groups within species. For example: NSS, SSS, A, or B for maize.
- germplasm_id: A higher level of ID. For example: MGID.
- germplasm_subsp: Sub species grouping of germplasm. This could be different for each crop, but for example, would be dent, flint, sweet, or pop for maize, indica, and japonica for rice, breed bread wheat, durum wheat for wheat, etc.
- par1: The germplasm name for parent 1 of the germplasm (in a biparental cross this would be the female).
- par2: The germplasm name for parent 2 of the germplasm (in a biparental cross this would be the male).
- par3: The germplasm name for parent 3 of the germplasm.
- par4: The germplasm name for parent 4 of the germplasm.
- pedigree: The pedigree for the germplasm name.
- seed_source_id: Seed source ID for the germplasm.

- name: A required field to describe the sample name. This is usually the name that gets sent to the lab for processing. Note Note: A unique sample (within a GDM Crop Database) is defined by the unique combination of the project_name, dnasample_name, and dnasample_number so the dnasample_name does not need to be unique within a project or across projects. The dnasample name in a project can also be the same name as the germplasm name. This is often the case for legacy data existing before sample tracking or LIMS systems were in place.
- uuid: A required field for a unique ID that can be used to identify a sample or sub-samples generated from a plot or plant. We advocate the use of a Universal Unique Identifier which is a 128-bit number used to identify information in computer systems eg 123e4567-e89b-12d3-a456-426655440000. Such a uuid will help to identify and track samples generated from across multiple institutes and systems. As long identifiers may not be manageable by vendors, the sample name can be sent to the vendor, and the uuid maintained internally.
- platename: An optional field describing the plate name that the sample is in. This can be a number (1,2,3,4, etc.), or a name given by the lab.
- num: A required field describing the numerical order of the sample within a project. For example, 1-96 for a 96 well plate. The combination of dnasample name and num need to be unique within the project.
- well_col: An optional field describing the plate column coordinates for the sample. For example, 1-12 for a 96 well plate.
- well_row: An optional field describing the plate row coordinates for the sample. For example, A-H for a 96 well plate.
...
- ref_sample: A standard "Reference" sample against which all other germplasms are compared. This is also called a "gold standard" line. As this is not a CV term, the crop community needs to decide on standards for naming ref samples.
- sample_group: The grouping of germplasm that has the utility to the breeder for analysis purposes. For example: a population and its parents that need to be grouped for data analysis.
- sample_group_cycle: The cycle of germplasm grouping. For example: different generations of a population and its parents that allow for further grouping withing the germplasm group.
- sample_parent_prop: This can be used to describe the type of parent, for example: female/male or DP/RP (donor/recurrent parent)
- sample_type: The type of tissue sampled. For example, : leaf, seed, bulk seed, or bulk plant. You can map the term to Plant Ontology (PO) if available. For example: if leaf sample is taken, it could be mapped to PO term leaf with its identifier PO:0025034 or leaf_PO:0025034.
- trial_name: The trial name for the field experiment that the sample is coming from, or fieldbook.
