The fungus Botrytis cinerea Pers. At present, it is accepted that B. Berries that are exposed to sunlight, particularly UV-B light, produce thicker wax layers than berries under shaded conditions Keller et ala.

Incidence of fungal diseases in the area is lower compared with other viticulture regions of the world. Quantification of disease progression. Estimated Fst value comparing all French vod together as only one population.

Perforationen in der Cuticula von Weinbeeren als morphologischer Faktor der Botrytisresistenz. Role of latent infections. Group II has a wider host range, and includes the isolates that are most deleterious for grapevines and other hosts. The information on genetic diversity that was obtained and the population differentiation data suggest the need of a further study, in order to establish the biological impact of these findings e.
