Suitability for cultivation and agronomic production
Chasan must be trellised and pruned short due to it being a fertile and productive variety which grows long branches with a drooping bearing.
Susceptibility to diseases and pests
This early variety resists very well to grey rot but is susceptible to phomopsis, powdery mildew and to a lesser extent to downy mildew and mites.
Technological potentiality
The bunches are very large and the berries are medium in size. Chasan produces aromatic products that are sensitive to oxidation. This variety is well suited to cool areas as acidity drops quickly during maturation and often reaches very low levels in southern regions.
Clonal selection in France
The only certified Chasan clone carries the number 538.
