Since the renewal of the French vineyard after the Phylloxera crisis, the panorama of cultivated varieties has dramatically changed. This current genetic erosion is due to the increasing interest in some cultivars that are widely spread out. Meanwhile, clonal selection has contributed to the development of these grape varieties driving towards a massive loss of […]

Varieties and rootstocks: an important mean for adaptation to terroir

A large genetic diversity exists among V. vinifera varieties, but also among cultivated rootstocks. This diversity is important to adapt plant material to different environmental conditions and contributes to the expression of terroir. Plasticity, i.e. the level of modification of the expression of individual characteristics of a genotype in different environments, is also important for […]
