1.A rootstock not belonging to a variety, shall, on request, be officially certified as pre-basic material if it has been found to fulfil the following requirements:
(a)it is directly propagated, by vegetative or sexual propagation from a mother plant; in the case of sexual propagation pollinating trees (pollenisers) are directly produced by vegetative propagation from a mother plant;
(b)it is true to the description of its species;
(c)it is maintained pursuant to Article 8;
(d)it complies with the health requirements of Article 10;
(e)where the Commission has granted a derogation pursuant to Article 8(4) to grow pre-basic mother plants and pre-basic material in the field under non-insect proof conditions, the soil complies with Article 11;
(f)it complies with Article 12 concerning defects.
2.The mother plant referred to in paragraph (1)(a) shall either have been accepted in accordance with Article 6, or have been obtained by multiplication in accordance with Article 13 or micropropagation in accordance with Article 14.
3.Where a rootstock which is a pre-basic mother plant or pre-basic material no longer fulfils the requirements of Articles 8 to 12, the supplier shall remove it from the vicinity of other pre-basic mother plants and pre-basic material. That removed rootstock may be used as basic, certified or CAC material provided that it fulfils the requirements set out in this Directive for the respective categories.
Instead of removing that rootstock, the supplier may take appropriate measures in order to ensure that that rootstock complies with those requirements again.
