Behavior of disease resistant grapevine varieties to downy mildew (Plasmopara viticola) infections in the Castelli Romani area (Central Italy)

Abstract

At CREA – Centro di Ricerca di Viticoltura ed Enologia, based in Velletri (RM), an experimental vineyard including 10 downy mildew resistent/tolerant grape varieties and two susceptible varieties was set up with the principal goal to evaluate the behavoir of these varieties in term of resistance to downy mildew (Plasmopara viticola). This evaluation, together to oenological studies, are necessary to register them also in Regional Register (in Lazio region). Monitoring of behavior towards Plasmopara viticulture of resistant vines were done in 2020 and 2021 at different times(phenological stages) and until harvesting, according to an international standard code BBCH a centesimal phenological scale, based on coding system. Data analysis show differences in behaivor depending on the cultivar and the meteorological conditions during the two-year growing seasons.

Evolution of oak barrels C-glucosidic ellagitannins in model wine solution

Oak wood has a significant impact on the chemical composition of wine, leading to transformations that influence its organoleptic properties, such as its aroma, structure, astringency, bitterness and color. Among the main extractible non-volatile polyphenol compounds released from oak wood, the ellagitannins are found [1].

Single plant oenotyping: a novel approach to better understand the impact of drought on red wine quality in Vitis x Muscadinia genotypes

Adopting disease-tolerant varieties is an efficient solution to limit environmental impacts linked to pesticide use in viticulture. In most breeding programs, these varieties are selected depending on their abilities to tolerate diseases, but little is known about their behaviour in response to abiotic constraints.
