DUS testing of agricultural crops, vegetables and potatoes. Vegetable reference collection - VS03002

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 Breeder` Rights candidates. DUS tests for pulses, potatoes and vegetable species are conducted by Scottish Institutions.
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.
Scientific input includes taxonomy, providing up to date methods for field trial design, statistical anyalyses, use of imaging technology and biochemical and molecular techniques.
DUS test centres advise on adapting testing systems to accommodate new types of varieties, new ways of discriminating between varieties, and on more consistent and efficient testing methods

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.
