The increasing effort towards sustainable production techniques isexpressed in various ways and also with the introduction of selected plant varieties in culture for resistance to the most serious plant diseases. In the viticultural field, for some decades now, we have spoken of grapes resistant to Peronospora (Plasmopara viticola). Some of these have been obtained and tested in northern environments, eg in Germany. In Italy they were introduced in Trentino Alto Adige and Veneto, but not yet in the vineyards of the peninsular regions.
The resistant vines are gaining interest in all the producing countries of the world, as also confirmed at the technical meeting of the OIV at the end of March 2019.
THE CREA-VE, Research Centre for Viticulture and Enology and ARSIAL, the Regional Agency for Development and Innovation of Agriculture of Lazio, in 2016 implanted a collection of 10 resistant vines in the experimental vineyard of Velletri (RM).
In 2018 the first harvest was carried out. In this work we want to report the first agronomic results recorded in the period in relation to the seasonal trend and the first oenological evaluations of the 10 cultivars in the Castelli Romani area.
Article based on the poster presented at the at the 12th edition of Enoforum (Vicenza, Italy, May 21-23, 2019).
