Conservation of intravarietal diversity in France: exhaustive overview and perspectives


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 genetic resources by the use of ± 400 clones only. Thus, since the middle 90’s, many local repositories have been established by the IFV and French selection partners.
These repositories are established in complementarity with INRA Domaine de Vassal for the maintenance of Vitis vinifera (and other species of Vitis) and the IFV for selected clones. Today, the total of local repositories has reached 151 holding 113 registered varieties and over than 15 000 clones. Passport data of this material is recorded in a national online data-base.
Some clonal research programs have been achieved using material held in repositories. For example, it is the case with Syrah for new material resistant to Syrah decline, Cabernet franc and Tannat for new clones with lower fertility, etc….

This presentation will also give a large overview on the French policy of conservation (history, recent developments, and tools for the management), the organization of the different levels of repositories, and some data including endangered and neglected cultivars that require short term actions to be engaged. Today, there are still 77 varieties without any repository. Some were widely used in the middle of the XXth century but have drastically decreased. Indeed, time has come now to engage a large inventory of old vineyards. Since the last decade, about 50 000 ha of old vineyards have been definitively discarded. That means that opportunities to find diversity are being reduced year after year.
Due to this coordination and partnership, some programs have recently been started : Jurançon noir, Muscat d’Alexandrie, Sacy, etc…
But it seems clear that means are required to prospect additional ressources, plant and manage repositories. Unfortunately, the wine industry does not necessarily consider these programs as a priority even if, in the long term perspective, there are good reasons to have everyone concerned and involved: climate changes, global competition, standardization, etc….

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
