Towards a relationship between institutional clonal selection, mass selection and private clonal selection of grapevine cultivars

Un 94 % del viñedo español se cultiva con métodos y técnicas propias de los sistemas agrícolas desarrollados en secano en regiones de clima semiárido, donde las precipitaciones anuales raramente exceden los 500 mm

Climate is one of the main conditioning factors of winemaking. In this context, bioclimatic indices are a useful zoning tool, allowing the description of the suitability of a particular region

Wine is a complex matrix whose composition depends on climatic, agricultural, and winemaking factors, making quality control and authenticity assessment critical in the global market.

Climate change will increase the frequency of water deficit experienced in certain european regions, due to increased evapotranspiration and reduced rainfall during the growing cycle. We therefore need to find ways of adaption, including the use of more drought-tolerant planting material. In addition to the varieties used as grafts and involved in the wine ypicity of our wines, rootstocks selection is a relevant way of adapting to more restrictive environmental conditions.

As knowledge about the oenological potential of disease-tolerant grape varieties (PIWI) continues to grow and consumer demand for product safety and sustainable production increases, more governments worldwide are permitting the cultivation of these varieties [1].
