How to deal with the Green Deal – Resistant grapevine varieties to reduce the use of pesticides in the EU

Abstract

With its Farm-to-Fork Strategy, which is a part of the European Green Deal, the European Union aims at reducing the amount of pesticides used in agriculture by 50% until 2030. As viticulture uses around 70% of the fungicides in the EU, there is substantial pressure on winemakers to reduce their pesticide input. On top of the political goal, winegrowers face increased pressure from the public demanding a more sustainable production of wine. Since the introduction of downy mildew, powdery mildew and other pests and pathogens from North America to Europe in the 19th century, substantial breeding efforts were undertaken to develop disease-resistant varieties and reduce the amount of plant protection products needed for harvesting healthy grapes. Today’s winegrowers in Europe can choose from many new varieties allowing them to reduce fungicide input by 50-80% and produce high quality wines on par with the valued traditional cultivars. This review will provide an overview on the current situation of disease-resistant varieties in European viticulture. Selected European breeding institutions and private breeders will be introduced and their most important grapevine varieties will be presented. Many resistant varieties are available for winegrowers today, however, even the most robust new varieties will not lead to a more sustainable viticulture if the market does not accept them. The adoption and acceptance of new varieties by winegrowers and consumers is still rather low, but the interest in these varieties is rapidly growing. The production of grafted vines of disease-resistant grapevine varieties allows the estimation that the area of disease-resistant varieties will significantly grow in the next years in Europe.

Haplotype-resolved genome assemblies of Chasselas and Ugni Blanc

Haplotype-resolved genome assemblies were produced for Chasselas and Ugni Blanc, two heterozygous real-field genetic pool Vitis vinifera cultivars by combining high-fidelity long-read sequencing (HiFi) and high‐throughput chromosome conformation capture (Hi-C). The telomere-to-telomere full coverage of the chromosomes allowed us to assemble separately the two haplo-genomes of both cultivars and revealed structural variations between the two haplotypes of a given cultivar.

Preliminary studies on polyphenol assessment by Fourier transform-near infrared spectroscopy (FT-NIR) in grape berries

NIR spectroscopy has widely been tested in viticulture as powerful alternative to traditional analytical methods in the field of quality evaluation. NIR instruments have been used for assessing must and wine quality features in several works, but little information regarding their application on whole berries for polyphenol determination is available.

Evaluation of methods used for the isolation and characterization of grape skin and seed, and wine tannins

Validation of the phloroglucinolysis and RP-HPLC method showed selectivity and repeatability within acceptable limits for all investigated matrices. Recovery of polymeric phenols by SPE was also acceptable.

Identification and formation kinetic study of phenolic compounds-volatile thiols adducts by enzymatic oxidation

By using HPLC-ESI-MS, 1H, 13C and 2D NMR, new addition products between catechin, epicatechin, caftaric acid and 3SH were characterized. Caftaric acid formed more rapidly adducts with 3SH than catechin and epicatechin in the absence of other nucleophiles.
