dc.description.abstractEnBotrytis cinerea causes one of the most serious diseases in grapevines namely Botrytis Bunch Rot (BBR). A classification of different grapevine cultivars (cvs.) according to their susceptibility to B. cinerea is an essential management indicator in Integrated Pest Management. Although such classifications are available, they are based mostly on professional experience rather than experimental results. The main aim of this study was to compare and classify the susceptibility of different winegrape cvs to B. cinerea and its relation to fruit maturity within two contrasting climatic and cropping conditions. Between 2011 and 2015, three field trials were carried out in Chile and France, including 13 common cvs. Both, incidence and severity of the disease were evaluated at harvest and indices of susceptibility (SI) and maturity (FMat) were calculated on a per-site basis. The significant differences in disease incidence and severity observed among cvs. led to a similar susceptibility classification in both countries. Cabernet Sauvignon, Cabernet Franc, Grenache Noir and Petit Verdot were the most resistant cvs., whereas Gewürztraminer and Sauvignon Blanc were the most susceptible ones. Moreover, an exponential and positive relationship was established between SI and maturity. The cultivar classification according to the susceptibility to B. cinerea was similar in both countries, despite the contrasting climatic conditions and cropping practices. These findings might be of interest for choosing cultivars more resistant to B. cinerea in order to reduce the number of specific anti-Botrytis fungicide applications.
