Suitability for cultivation and agronomic production

This variety can be managed with short or long pruning. Depending on climatic conditions, it is sometimes susceptible to millerandage. It is also rather susceptible to magnesium deficiency (especially in potassium-rich soils) and to dessication of the stems.
Susceptibility to diseases and pests

Chasselas is not very susceptible to grey rot and mites. On the other hand, it is sensitive to powdery mildew, phomopsis and eutypa dieback.
Technological potentiality

The bunches and berries are medium in size. The skin is thin, the pulp is soft and juicy with a pleasant taste. Chasselas has a good storage and transport capacity. Wines produced from Chasselas are rather fine, but often rather neutral in terms of aromatic potential and sometimes lack acidity.
