Classification of winegrape cultivars in Chile and France according to their susceptibility to Botrytis dnerea related to fruit maturity

摘要

Background and Aims: The susceptibility of winegrape cultivars to Botrytis cinerea is a debated topic, and the available classifications are based on professional experience rather than on experimental data. The main aim of this study was to compare and classify the susceptibility of several winegrape cultivars to B. cinerea and its relation to fruit maturity under two contrasting climatic and cropping conditions.
