Division Sampling and testingF1

Propagating material and fruit plants of the pre-basic category of Prunus armeniaca L. , Prunus avium L. , Prunus cerasus L., Prunus domestica L., and Prunus dulcis (Miller) Webb, shall derive from mother plants, which have been tested within the previous growing season and found free from Plum pox virus.

Pre-basic rootstocks of Prunus cerasifera Ehrh. and Prunus domestica L. shall derive from mother plants, which have been tested within the previous growing season and found free from Plum pox virus. Pre-basic rootstocks of Prunus cerasifera Ehrh. and Prunus domestica L. shall derive from mother plants, which have been tested within the previous five growing seasons and found free from Candidatus Phytoplasma prunorum Seemüller & Schneider.

Each flowering pre-basic mother plant shall be sampled and tested for Prune dwarf virus and Prunus necrotic ringspot virus one year after its acceptance as a pre-basic mother plant and with subsequent intervals of one year. In the case of Prunus persica , each flowering pre-basic mother plant shall be sampled one year after its acceptance as a pre-basic mother plant and tested for Peach latent mosaic viroid. Each tree planted intentionally for pollination and, where appropriate, the major pollinating tree s in the environment shall be sampled and tested for Prune dwarf virus and Prunus necrotic ringspot virus.

Each pre-basic mother plant shall be sampled five years after its acceptance as a pre-basic mother plant, and with subsequent intervals of five years, and tested for Candidatus Phytoplasma prunorum Seemüller & Schneider and Plum pox virus. Each pre-basic mother plant shall be sampled ten years after its acceptance as a pre-basic mother plant, and with subsequent intervals of ten years, and tested for RNQPs, other than Prune dwarf virus, Plum pox virus and Prunus necrotic ringspot virus, relevant for the species, as listed in Annex II, and tested in the case of doubts concerning the presence of RNQPs listed in Annex I. A representative portion of pre-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.
