Definitions

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

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

(2) ‘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 2

Minimum conditions for pre-basic seed potatoes

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 pests: Pectobacterium spp., Dickeya spp., Candidatus Liberibacter solanacearum, Candidatus Phytoplasma solani, Potato spindle tuber viroid, Potato leaf roll virus, Potato virus A, Potato virus M, Potato virus S, Potato virus X, and Potato virus Y;

(b) 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) RNQPs, or symptoms caused by the respective RNQPs, shall not be present above the thresholds on the pre-basic seed potatoes as set out in the following table: RNQPs or symptoms caused by RNQPs Threshold for the presence of RNQPs on the growing plants for pre-basic seed potatoes Blackleg (Dickeya Samson et al. spp. [1DICKG]; Pectobacterium Waldee emend. Hauben et al. spp. [1PECBG]) 0 % Candidatus Liberibacter solanacearum Liefting et al. [LIBEPS] 0 % Candidatus Phytoplasma solani Quaglino et al.

Member States shall provide that pre-basic seed potatoes may be marketed as ‘Union grades PBTC’ and ‘Union grade PB’, in accordance with the conditions set out in the Annex.

Compliance with the requirements of points (b) and (d) of paragraph 1 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 (a) of paragraph 1 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 (a) of paragraph 1 shall be established by official testing, or testing under official supervision, of the clonal stock.

Article 3

Minimum conditions for lots of pre-basic seed potatoes

Member States shall provide that lots of pre-basic seed potatoes shall satisfy the following minimum conditions:

(a) presence of earth and extraneous matter shall not exceed 1,0 % by mass;

(b) the number of potatoes affected by rots, other than ring rot or brown rot, shall not be present in a quantity exceeding 0,2 % by mass;

(c) the number of potatoes with external blemishes, including misshapen or damaged tubers, shall not exceed 3,0 % by mass;

(d) the number of potatoes affected by common scab over more than one third of their surface shall not exceed 5,0 % by mass;

(e) shrivelled tubers due to excessive dehydration or dehydration caused by silver scurf shall not exceed 0,5 % by mass;

(f) lots of pre-basic seed potatoes shall comply with the following requirements concerning the presence of RNQPs, or diseases caused by the respective RNQPs as set out in the table: RNQPs or symptoms caused by RNQPs Threshold for the presence of RNQPs on the lots of pre-basic seed potato Candidatus Liberibacter solanacearum Liefting et al. [LIBEPS] 0 % Ditylenchus destructor Thorne [DITYDE] 0 % Black scurf affecting tubers over more than 10 % of their surface as caused by Thanatephorus cucumeris (A.B. Frank) Donk [RHIZSO] 1,0 % Powdery scab affecting tubers over more than 10 % of their surface as caused by Spongospora subterranea (Wallr.) Lagerh. [SPONSU] 1,0 %

(g) the total number of potatoes, as referred to in points (b) to (f), shall not exceed 6,0 % by mass.

Article 4
