Vitis vinifera enters dormancy in autumn to face adverse winter conditions and, then, resumes growth and budbreak (BB) in spring, when optimal climate conditions occur.

Water limitation is a major environmental constraint affecting grapevine productivity and fruit quality worldwide.

In order to maintain grapevine production and quality under fluctuating and stressful environments, we urgently need some innovative genetic solutions.

Breeding for complex quantitative traits remains a major challenge in perennial crop systems, particularly for traits related to water use efficiency (WUE), which are strongly influenced by environmental variation and difficult to phenotype at scale.

Although the grapevine (Vitis vinifera) is a thermophilic plant wich is well adapted to regions with warm and dry summers, it is increasingly affected by climate change.

Climate change increasingly challenges viticulture through heatwaves and drought on the one hand as well as high precipitation levels on the other.

High-quality planting material is important for sustainable viticulture, and the early establishment of grapevine cuttings depends on rapid adventitious rooting and vigorous shoot growth.

Freezing tolerance is an important trait affecting grapevine winter survival in the Northern United States.

Mediterranean viticulture faces increasing pressure from rising temperatures, altered phenology, and intensified disease incidence.

Clonal selection represents a key approach in the genetic improvement of grapevines. Its primary objective is to fix, within commercial clones, the cumulative somatic variations that have arisen over time in vegetatively propagated vineyards and that confer valuable agronomic traits.
