Specialist collections

Alongside the main UKVGB collection, we manage a number of specialist research collections. These specialist research collections often represent a lifetimes work of an individual researcher. We are pleased to be able to ensure their work is safeguarded for the future.

VeGIN sets

The VeGIN projectLink opens in a new window has created sets of genetically fixed lines, representing a structured sampling of diversity across a genepool for a number of key crop groups.

These "Diversity Fixed Foundation Sets" (DFFS) have been developed for:

• Brassica oleracea Diversity Fixed Foundation Set (BolDFFS)Link opens in a new window
• Brassica C genome Diversity Fixed Foundation Set (BCgDFFS)Link opens in a new window

• Carrot Diversity SetLink opens in a new window

• Lettuce Diversity SetLink opens in a new window

• Onion Diversity SetLink opens in a new window 

Please contact Graham Teakle to obtain seed from these diversity sets.

UKVGB accessions which were included in the original founding lines of these sets can also be found using the UKVGB collection search. Use the advanced search "Accession Group" function, and then select the relevant group you are interested in.
