THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Council Directive 2002/56/EC of 13 June 2002 on the marketing of seed potatoes(1), and in particular Article 18(c) thereof,                        

Whereas:

(1)Seed potatoes progressively accumulate diseases with each cycle of multiplication. Properly functioning seed potato production                              systems thus require healthy starting material that is multiplied with a minimal rate of degeneration.

(2)Different national standards on the production of pre-basic seed potatoes have obstructed the marketing of those potatoes                              throughout the Union, and have impeded the functioning of the internal market. Therefore it is appropriate to establish minimum                              conditions under which pre-basic seed potatoes may be marketed throughout the Union. Those conditions should concern diseases,                              symptoms, defects and production requirements for pre-basic seed potatoes, and lots of those potatoes, to ensure the production                              and marketing of healthy and high quality pre-basic seed potatoes.

(3)Those conditions should take into account the standard of United Nations Economic Commission for Europe (UNECE), concerning                              the marketing and commercial quality control of seed potatoes, as well as the relevant standards of the International Plant                              Protection Convention (IPPC) and the European and Mediterranean Plant Protection Organization (EPPO), in view of technical                              and scientific developments. Those standards aim at helping facilitate international trade, encouraging high quality production,                              improving profitability and protecting consumer interests.

(4)In view of the production practices of suppliers, and the demand of the users of pre-basic seed potatoes, it is appropriate                              that the minimum conditions for pre-basic seed potatoes also include the possibility for marketing them as Union grades. Two                              Union grades should apply for pre-basic seed potatoes (‘Union grade PBTC’ and ‘Union grade PB’), in line with the existing                              production practices concerning pre-basic seed potatoes of grade PBTC, and pre-basic seed potatoes of grade PB. Different                              conditions per grade should thus be adopted concerning diseases, symptoms, defects, production requirements and generations                              for those grades.

(5)In order to be effective, those rules should also set out provisions concerning official testing and official field inspections.

(6)The measures provided for in this Directive are in accordance with the opinion of the Standing Committee on Seeds and Propagating                              Material for Agriculture, Horticulture and Forestry,

HAS ADOPTED THIS DIRECTIVE:

## Article 1U.K.Definitions

For the purposes of this Directive, the following definitions shall apply:

‘mother plant’ means an identified plant from which material is taken for propagation;

‘micro-propagation’ means the practice of rapidly multiplying plant material to produce a large number of plants, using culture                              *in vitro* of differentiated vegetative buds or meristem taken from a plant.                           

## Article 2U.K.Minimum conditions for pre-basic seed potatoes

1.Member States shall ensure that pre-basic seed potatoes satisfy the following minimum conditions:                  

(a)they derive from mother plants which are free from the following harmful organisms: *Pectobacterium* spp., *Dickeya* spp., Potato leaf roll virus, Potato virus A, Potato virus M, Potato virus S, Potato virus X, and Potato virus Y;                  

(b)they are free from symptoms of blackleg;                  

(c)the number of growing plants not breeding true to the variety and the number of plants of a different variety together, shall                        not exceed 0,01 %;                  

(d)in the direct progeny, the number of plants showing symptoms of virus infection shall not exceed 0,5 %;

3.Compliance with the requirements of paragraph 1(b), (c) and (e) shall be established through official field inspections. In                        case of doubt, those inspections shall be supplemented by official tests on leaves.                  

Where methods of micro-propagation are used, compliance with point 1(a) shall be established by official testing, or testing                     under official supervision, of the mother plant.                  

Where methods of clonal selection are used, compliance with point 1(a) shall be established by official testing, or testing                     under official supervision, of the clonal stock.
