Disease resistant grapevine varieties and quality: the case of Bouquet varieties

Abstract

The disease resistant grapevine varieties (ref A. Bouquet) were obtained by INRA from 4 or 5 generations of backcrossing between Muscadinia rotundifolia and Vitis vinifera and exhibit a high level of resistance against downy and powdery mildew. These varieties carry the resistance genes RUN 1 and RPV1, with several other secondary genes at one chromosomal locus. Agronomic criteria were studied for all these selections. Among the selected grapevine species, some have high levels of polyphenols. Some (white and red) have a high aromatic potential, while others have low sugar contents (135 g/L to 150 g/L) and adapted sugar/acidity ratio. All these characteristics were combined to design a new set of vine cultivars dedicated to the production of either low-alcohol wines, grape juices, or classical wines. Since 2012, within a France Agrimer/CIVL/INRA financial framework, 10 plots (0.5 ha each) were planted at INRA Pech Rouge with 8 resistant grape varieties (ref A. Bouquet) in order to examine long-term resistance to diseases and to define quality criteria for the classification of the wines obtained from these new grape varieties.

Behavior of Vine Varieties Resistant to Fungal Diseases in the Somontano Region

“…It should be clarified that a large variability according to the winemaking process has been reported for PIWI wines [62]. Salmon et al [63], who studied the sensory perception of wines prepared from a disease resistant grapevine variety obtained by the French Institut National de la Recherche Agronomique−INRA (ref A. Bouquet, var.…”

Resurgence of minority and autochthonous grapevine varieties in South America: a review of their oenological potential

“…However, the introduction and spread of these grapevine varieties, mostly in South America, has caused a massive loss of minority and autochthonous grapevine varieties traditionally grown in different wine‐growing regions . Moreover, the disappearance of a large number of old grapevine varieties and the varietal homogenization of the vineyard entail an increase in genetic vulnerability in relation to the spread of pathogens against which the cultivated varieties are not resistant …”

“…[11][12][13][14][15][16] Moreover, the disappearance of a large number of old grapevine varieties and the varietal homogenization of the vineyard entail an increase in genetic vulnerability in relation to the spread of pathogens against which the cultivated varieties are not resistant. 15,[17][18][19] In recent years, a new productive trend has gradually been introduced in the world wine industry, favoring the production and preservation of minority grapevine varieties. 15,16,[20][21][22][23][24][25][26][27][28][29] In contrast to the general trend of producing wine from globally disseminated grapevine varieties, associated with the French paradigm, there is a slight tendency to increase the number of studies of minority or autochthonous grapevine varieties.…”

Somatic Variation and Cultivar Innovation in Grapevine

“…All species within the genus Vitis are cross-fertile and the identification of sources of genetic resistant for Vitis vinifera pathogens and pests mainly in other American or Asian species opened the possibility to improve grapevine varieties through classical breeding strategies. This approach has been successfully developed during the twentieth century and new resistant grapevine varieties have reached the markets with different success rates [7][8][9][10]. Furthermore, rising knowledge of the grapevine genome and the development of new genomics and molecular techniques in the last decade have triggered a renewed interest for breeding given, the pressure to reduce the use of pesticides in viticulture [10].…”
