The project aims to improve the traceability of the grapevine propagation material, with particular attention to the clonal trueness-to-type and to the actual application of preventive treatments against phytoplasmatic diseases.

As for the genetic traceability, the study will concern molecular markers (SNPs) able to allow identification of grapevine clones. Although a high number of SNPs has been characterized up to now, they seem to be unsuitable for clonal fingerprinting. Basing on the results of the project “Nebbiolo Genomics”, which achieved the genome sequencing of three Nebbiolo clones, new SNPs will be identified and characterized; particular attention will be paid to the SNPs belonging to coding sequences, therefore potentially representing functional markers associated to interesting genes.

Radio-frequency identification (RFID) technology will be used to store and retrieve a wide range of information in glass tags implanted in grapevine grafted cuttings. All data concerning the single plant, suitable for tracing it along its nursery and vineyard path, can be be stored in the tag together with data regarding specific phytosanitary treatments (such as hot water treatments against phytoplasmatic diseases). The possible influence of the tags on the plants will be checked during the growth in the nursery; commercial vineyards – whose plants were tagged before planting – will be monitored recording vegetative and productive data.

The project will be carried out in collaboration with Vignaioli Piemontesi, Enocontrol, Pisa University and TOS.CO.VIT.
