Allium crops are grown and consumed worldwide. Our aim is to provide solutions to major challenges to onion and leek production, to enhance yield and quality for the benefit of producers and consumers.

The Genetic Resources Unit and Crop Breeding

  • The Genetic Resources Unit seed collection has over 2400 accessions of Allium including onion, leek and wild species.
  • The Vegetable Genetic Improvement Network (VeGIN) is a Defra-funded project to bring together research focused on key vegetable crops. The Network encourages collaborations between industry and researchers to address how genetic improvement of crop varieties can contribute to a sustainable increase in food production to meet the twin challenges of food security and climate change. For onion, the project aims to deliver:
