DUS Testing - VS03001

It is a requirement of EC directives that new varieties of agricultural and vegetable species be entered on an EC National List before they can be marketed in the commumity.
A voluntary scheme exists for breeders to protect their investment in breeding new varieties - Plant Breeders` Rights.
Tests to determine Distinctness, Stability and Uniformity (DUS)are a statutory requirement for both National List and Plant Breeders` Rights candidates.
Tests are conducted using protocols agreed by the UK National Authorities and are based on internationally agreed methods and standards.
Growing trials are normally conducted over two growing seasons to establish whether a candidate is DUS. Defra pay NIAB to undertake this work for a range of cereals, oilseeds pulses and fodder crops, and ornamental species.
Costs are recouped through fees to applicants.

More information about National Listing and Plant Breeders` Rights can be found at This site gives details of contacts at the Plant Variety and Seeds Division who can give further information about National Listing, and DUS testing.
