The use of vine hybrids <\/strong> that show resistance to powdery mildew and downy mildew can improve economic and environmental sustainability <\/strong> in a world that increasingly needs protection and guarantees from 'man.<\/p>\n We are only at the dawn of this journey and and the credentials of vine hybrids have yet to be confirmed by their large-scale use.<\/p>\n In this regard, I remember a trip made about 6 years ago to Freiburg where the search for hybrids for the production of red wines was very intense.<\/p>\n The world wine sector has actually already been involved in the cultivation of hybrids. It is estimated that after World War II they could represent shares close to 50% of the entire world planted area.<\/p>\n Inizialmente si trattava di ibridi direttamnete ottenuti da incrocio spontaneo tra viti americane per combattere soprattutto la fillossera dotati in genere di una certa tolleranza alla peronospora.<\/p>\n This first generation, in addition to showing little resistance to phylloxera, had Vitis Lambrusca among its parents. This was the carrier of marker molecules such as methylanthralinated and 2-aminoacetofenone, the chemical basis of the foxy or volpino scent, and fureaneol, responsible for the strawberry-like in addition to the presence of methyl alcohol.<\/p>\n A second generation of hybrids followed that excluded V. Lambrusca so that around 1960 France had about 400,000 hectares planted.<\/p>\n The modest qualitative <\/strong> levels of the wines obtained pushed in favor of the cultivation of the only Vitis vinifera grafted on American rootstock.<\/p>\n We have reached the third generation where we have sought resistance to downy mildew and powdery mildew, without however neglecting the qualitative aspects of the wine.<\/p>\n Vitis vinifera was crossed with American vines and Asian vines in order to obtain a genetic makeup resistant to these diseases.<\/p>\n The pioneering nations in this field were Germany as mentioned above and Switzerland.<\/p>\n A limited number of fungicidal treatments would offer the great possibility of reducing the environmental impact. For many winegrowers <\/strong>, however, the doubt remains that this resistance can be overcome by pathogens as has already happened in some cases. The advice therefore remains to carry out a small number of interventions in the field in aid to the plant <\/strong>.<\/p>","protected":false},"excerpt":{"rendered":" Resistant vines in the field The use of hybrids of vines that show resistance to powdery mildew and downy mildew can improve economic and environmental sustainability in a world that increasingly needs human protection and guarantees.
