Pathogen Collection & Disease Resistance

One primary objective of the Defra-funded OREGIN project is to establish, characterise, and catalogue a world-wide collection of fungal pathogen isolates to underpin rapeseed breeding for disease resistance.

Leptosphaeria maculans

Phoma Stem Canker (Aggressive)

Download Isolate List (XLSX)

Considered the more aggressive species, infecting cotyledons, leaves, and stems leading to devastating crown cankers. The collection includes 135 isolates representative of world-wide distribution.

  • UK Isolates: 42
  • International: 135

Leptosphaeria biglobosa

Phoma Stem Canker (Upper Stem)

Download Isolate List (XLSX)

Linked to less-harmful upper stem lesions. This species is gaining importance as L. maculans is controlled by fungicides and resistance.

  • UK Isolates: 11
  • International: 41

Pyrenopeziza brassicae

Light Leaf Spot (LLS)

Download Isolate List (XLSX)

An economically important pathogen in the UK causing up to 30% yield reduction. Collection includes 270+ characterized isolates.

  • UK Isolates: 167
  • International: 291

Request Access

Once characterised, isolates are available to stakeholders and the research community. A signed Material Transfer Agreement (MTA) is required for all requests.
