This 'Science to Practice' event transmitted advances in genetic improvement of stone pine as producer of Mediterranean pine nuts, though the main issue was about the very grafting techniques used in this pine.

Presentations delivered a review of three decades of prospection, common garden evaluation, and selection of genotypes (elite clones) with superior pine cone production, aimed as scion donors for grafted plantations. Nursery techniques and costs were analysed. Invited speakers were specialists and technicians from the Spanish Ministry of Agriculture, the National Institute of Agricultural and Food Research and Technology, the regional Forest Administration of Castilla y León, TRAGSA SA and Forestal Catalana SA, involved in development and deployment of elite clones.
