At the Warwick Crop Centre we have our own genebank in the form of the Vegetable Genetic Resources Unit (GRU).

This GRU has a remit for collection, conservation, characterisation, documentation and research for a range of vegetable

crops and their wild relatives.

The genebank holds thousands of accessions representing different crop species.

For example, we have over 6000 Brassica accessions. The schematic below highlights how we

select a reference sample from the available diversity then fix the diversity in the form of homozygous lines.

Principle behind capturing genetic diversity in the form of Diversity foundation Sets, then fixing the diversity in the form of homozygous lines

The Vegetable Genetic Improvement Network is creating useable genetic resources for Brassica, Lettuce, Carrot and Onion. These are highlighted in the table below.

Fixed genetic resources produced by VeGIN - as of 050411 (B. napus is also part of OREGIN)

These data are to be updated. Many more fixed lines have now been produced.
