Abstract

[Autom. eng. transl.] Every year in viticulture, numerous fungicide treatments are carried out, against the main diseases of the vine such as downy mildew, powdery mildew and gray mold (caused respectively by Plasmopora viticola, Erysiphe necator and Botrytis cinerea). The extensive use of phytosanitary products, for a constant protection of the vineyard even in periods in which there is no real risk of infection, causes numerous losses in economic, social and environmental terms. Disease-resistant varieties are among the useful tools for the implementation of an integrated crop defense. The resistant genotypes, results from successive crosses between Vitis vinifera hybrids and wild species of Vitis spp., Aim to obtain vines that combine the characteristics of resistance to the main diseases of the vine inherited from the wild varieties and the high agronomic and qualitative standards inherited from the V . vinifera. The Department of Sustainable Plant Production Sciences (DI.PRO.VE.S.), of the Catholic University of the Sacred Heart of Piacenza, is engaged in the evaluation of the resistance of these genotypes in an analytical way, distinguishing the various components that characterize a infection. The detailed study of the individual components of resistance allows the characterization of the genotypes, the understanding of the mechanisms of resistance and their genetic control, with a consequent improvement in the phytosanitary defense of resistant varieties.
