ENHANCEMENT OF NATIVE AND LOCAL GRAPE VARIETIES IN THE CONTEXT OF CLIMATE CHANGE
a. Grapevine biodiversity, a valuable resource to face climate change-related vineyard issues – Tommaso Frioni (Università Cattolica el Sacro Cuore di Piacenza)
b. Identification and discrimination of grapevine cultivars genetic profile – Matteo Busconi (Università Cattolica el Sacro Cuore di Piacenza)
Vineyard sustainability is impaired by the negative effects on grapevine physiology and fruit ripening related to climate change. The traditional and innovative plant material available represents a relevant chance for a wine district to evolve and adapt, according to the environmental conditions. The three-year project ValorInVitis tested traditional and autochthonous cultivars, new crossings and innovative rootstocks as a source of innovation in the scenario of the Colli Piacentini wine district, whose competitiveness is currently strongly affected by warming trends. The performances of the different genotypes was evaluated together with their adaptation to different environments within the region. Finally, the genetic identity of each genotype was assessed with the most modern methods available in grapevine biotechnology.
