Division Sampling and testingF1

Mother plants which have been maintained in insect proof facilities

A representative portion of basic mother plants shall be sampled every three years and tested concerning the presence of Prune dwarf virus, Prunus necrotic ringspot virus and Plum pox virus. A representative portion of basic mother plants shall be sampled every ten years and tested concerning the presence of Candidatus Phytoplasma prunorum Seemüller & Schneider.

Mother plants which have not been maintained in insect proof facilities

A representative portion of basic mother plants, other than those intended for the production of rootstocks, shall be sampled every year and tested for Plum pox virus in order to have all plants tested within an interval of ten years.

A representative portion of basic mother plants, intended for the production of rootstocks shall be sampled every year and tested concerning the presence of Plum pox virus and found free from that RNQP. A representative portion of basic mother plants of Prunus domestica L. intended for the production of rootstocks must be sampled and tested in the previous five growing seasons concerning the presence of Candidatus Phytoplasma prunorum Seemüller & Schneider and found free from that RNQP.

A representative portion of basic mother plants shall be sampled and tested in the case of doubts concerning the presence of Xanthomonas arboricola pv. pruni (Smith) Vauterin et al. A representative portion of basic mother plants shall be sampled and tested every ten years on the basis of an assessment of the risk of infection of those plants concerning the presence of RNQPs, other than Candidatus Phytoplasma prunorum Seemüller & Schneider, Prune dwarf virus, Prunus necrotic ringspot virus and Plum pox virus, listed in Annex II, and tested in the case of doubts concerning the presence of RNQPs listed in Annex I.

• Flowering mother plants

  A representative portion of flowering basic mother plants shall be sampled every year and tested for Candidatus Phytoplasma prunorum Seemüller & Schneider, Prune dwarf virus and Prunus necrotic ringspot virus on the basis of an assessment of the risk of infection of those plants.

  In the case of Prunus persica (L.) Batsch, a representative portion of flowering basic mother plants shall be sampled once a year and tested for Peach latent mosaic viroid on the basis of an assessment of the risk of infection of those plants. A representative portion of trees planted intentionally for pollination and, where appropriate, the major pollinating trees in the environment shall be sampled and tested Prune dwarf virus and Prunus necrotic ringspot virus on the basis of an assessment of the risk of infection of those plants.

• Non-flowering mother plants

  A representative portion of non-flowering basic mother plants which have been not maintained in insect proof facilities shall be sampled and tested every three years concerning the presence of Prune dwarf virus, Prunus necrotic ringspot virus and Candidatus Phytoplasma prunorum Seemüller & Schneider on the basis of an assessment of the risk of infection of those plants.
