National listing is a legal requirement for new varieties of the mainstream agricultural species. This process seeks to ensure that a new variety can only be brought to market if it passes stringent criteria and is deemed to be a genuinely new variety and a significant improvement over what is being currently marketed.
The UK National list documents the varieties of main agricultural and vegetable species, which are eligible for certification and marketing in the UK. To be added to the National list a variety must be distinct, uniform and stable (DUS) and for agricultural crops, have successfully completed two years of comparative trials and have achieved value for cultivation and use (VCU).
NIAB is a National test centre working on behalf of Defra to implement legislation. We are able to offer both DUS testing and VCU trials at our trial centres distributed around the major agricultural areas of England and Wales. Our trials and technical teams have many years’ experience in variety evaluation – with local knowledge and equipment to grow, manage, measure, monitor and harvest a wide range of crops. We are well placed along with our support services such as our Laboratory services, Pathology team and data handling and statistics department to implement the different stages of this scheme and ensure that the very best standards are maintained.
