About Germplasm #

Germplasm in DeltaBreed is a generic term for any reproductive unit of breeding material. Germplasm can be defined as individuals (trees, bushes, fish, seeds) or as populations (plots, bag of seed, semen, pollen). Germplasm can be sexually derived or clonal material. Germplasm is uniquely identified by system-assigned program-specific Germplasm IDs (GIDs).

DeltaBreed permits name duplicates. Clones and inbred lines are commonly referenced by the same name, but are differentiated in DeltaBreed by GID and breeding history.

Germplasm editing is not yet available from the user interface. We strongly suggest testing your germplasm uploads in a sandbox before uploading your production instance. Please request data fixes with your Breeding Insight or OnRamp coordinator.

All Germplasm #

You can review and find the GIDs for all germplasm within the BI platform from germplasm view.

seedling Use the column filters to do a “contains” filter for germplasm details. Select GID or Show Details hyperlinks to reveal germplasm details.

Germplasm Details #

Selecting the GID or Show Details hyperlinks reveal germplasm summary details. The tabs below offer additional details.

If a germplasm has a recorded pedigree history, the pedigree viewer will open with a default display of germplasm and its most recent progenitors.

seedling Select purple arrow icons in the pedigree view to reveal additional generations.

Expanded pedigree connections for a specific germplasm

Fully expanded pedigree of DG-001 GID 2799: This pedigree view includes bi-parental crosses and clonal advancements. Notice that there are two Unknown male parents, GID 0 . The pedigree view presumes that Unknowns with GID 0 are not the same germplasm entry and represents them as separate lineages.

Genotype #

(Beta feature. This tab is not offered in production programs.) If a germplasm has been genotyped, the SNP calls can be reviewed. See Genotyping Data for more information.

Germplasm Lists #

Germplasm Lists are created upon import.

File Import #

A user with breeder permissions is able to add germplasm to the database with or without pedigree connections using a germplasm import template.

Create germplasm lists using the template for a variety of purposes.

  1. Create new germplasm records
    • Migrate historical germplasm records into DeltaBreed
    • Active genealogy management, record crosses and advancements of germplasm previously established in DeltaBreed.
  2. Create lists of existing germplasm records to assist planning for experiments, crosses, sampling, etc.

README Worksheet #

The README worksheet provides instructions for each column of data that are required and optional for germplasm import. The required details are highlighted in green (name, breeding method, and source). Optional details are highlighted yellow and offer the ability to construct pedigree connections and record an External UID.

Breeding Methods Worksheet #

The Breeding Methods Worksheet outlines DeltaBreed’s predefined methods (65 generic methods). Explore additional methods customized for your program under Program Administration.

Create New Germplasm Records #

A breeder will want to create new germplasm records to (1) migrate historical germplasm records into DeltaBreed and to (2) actively manage genealogies by recording crosses and advancements of germplasm previously established in DeltaBreed.

Pedigree Connections

There are two ways to import germplasm with pedigree connections: (1) referencing GIDs of germplasm already established in the system or (2) referencing Entry No within import file. In the event that both are specified in the file, the connection will be made by GID.

Unknown Germplasm

  • Unknown germplasm can be specified in the import by (1) referencing entry number 0 or (2) referencing GID 0.
  • The pedigree viewer will treat Unknowns with GID 0 differently than other germplasm by assuming that Unknowns represent separate lineages.

Upload and Validate #

seedling Choose the edited template file then Upload and Validate.

File chosen and ready for upload and validation

seedling Review the imported germplasm entries before Confirming or Aborting the upload. In order to Confirm you must name the germplasm list. List description is optional.

Confirm gemrplasm details and record in DeltaBreed user interface

After successful confirmation, entries are accessible from the “All Germplasm” and the “Germplasm Lists” tab.

All germplasm accessible on UI

The 10 germplasm entries imported into this program were assigned GIDs 214-223. Notice that clonal germplasm only have a “female” parent. This parental assignment is irrespective of the sex of the parent germplasm.

Create List of Existing Records #

There are a variety of reasons to create lists of existing germplasm records. Germplasm lists are a first step towards planning for experiments, crosses, sampling, etc.

seedling Fill germplasm template with the germplasm of interest. Reference the GIDs in the system.

You must also include Name, valid Breeding Method, and Source, but note these values will be ignored upon import in favor of the existing germplasm record.

seedling Upload and validate.
