“…Due to this information, considerable economic investments and research efforts have been recently devoted to developing and improving FRG wines. For example, a 25-year backcrossing breeding program in France has generated a set of genotypes in which disease resistance is conferred by one single gene for downy mildew and another single gene for powdery mildew [ 21 ]. Similarly, in Italy, some botrytis-tolerant cultivars have been produced through intraspecific controlled crosses [ 14 ].…”

While there is evidence of consumers’ interest in wine sustainability, acceptance of innovations in wine production is not guaranteed. The current study addresses this issue by analyzing consumers’ acceptance of fungus-resistant grape (FRG) wines, a sustainable innovation that can substantially reduce the need for chemical inputs in viticulture. To do so, by means of an online survey including large samples of regular wine drinkers in Italy (N = 752), the UK (N = 858) and the USA (N = 856), the study compares individuals’ preferences for conventional wines with preferences for FRG wines. The study also explores whether FRG wine acceptance is influenced by informal or formal purchase occasion, by different types of information regarding the product, and by individual attitudinal characteristics. The findings show a general acceptance of FRG wines among consumers. In particular, consumers’ preferences for FRG wines on formal occasions are not significantly different from their preferences for conventional wine, whereas on informal occasions, consumers prefer FRG wines over conventional wines. Regarding the impact of information on participant choice, participants informed about the potential effects of FRG on sensory wine characteristics had lower preferences for FRG wines than those who read an information script regarding crop biodiversity. Last, individuals’ sustainability concerns and food technology neophobia had positive and negative influences on FRG acceptance, respectively. Overall, this research provides wineries, nurseries and policy-makers with important insights concerning the market potential of FRG wines in three key markets.

“…The varietal rigidity imposed by registered designations of origin, long juvenile phase, and high heterozygosity leads to costly and longer breeding technical times when classical breeding is applied on Vitis species [ 11 ]. Furthermore, although classical breeding and agrochemical approaches were considered effective at first, in the long run, they could lead to the emergence of resistant pathogen strains, since they mainly confer a qualitative type of resistance which is prevalently monogenic [ 12 ]. To cope with these threats, farmers have massively used pesticides, arousing conflicting opinions regarding environmental sustainability and the quality of viticulture and wine production processes [ 13 ].…”

Downy mildew, powdery mildew, and grey mold are some of the phytopathological diseases causing economic losses in agricultural crops, including grapevine, worldwide. In the current scenario of increasing global warming, in which the massive use of agrochemicals should be limited, the management of fungal disease has become a challenge. The knowledge acquired on candidate resistant (R) genes having an active role in plant defense mechanisms has allowed numerous breeding programs to integrate these traits into selected cultivars, even though with some limits in the conservation of the proper qualitative characteristics of the original clones. Given their gene-specific mode of action, biotechnological techniques come to the aid of breeders, allowing them to generate simple and fast modifications in the host, without introducing other undesired genes. The availability of efficient gene transfer procedures in grapevine genotypes provide valid tools that support the application of new breeding techniques (NBTs). The expertise built up over the years has allowed the optimization of these techniques to overexpress genes that directly or indirectly limit fungal and oomycetes pathogens growth or silence plant susceptibility genes. Furthermore, the downregulation of pathogen genes which act as virulence effectors by exploiting the RNA interference mechanism, represents another biotechnological tool that increases plant defense. In this review, we summarize the most recent biotechnological strategies optimized and applied on Vitis species, aimed at reducing their susceptibility to the most harmful fungal and oomycetes diseases. The best strategy for combating pathogenic organisms is to exploit a holistic approach that fully integrates all these available tools.
