Centennial seedless is slightly susceptible to grey rot.
Technological potentiality
Centennial seedless's bunches are large to very large and moderately compact. The berries are seedless, large, with a fairly thin skin, a firm pulp and a very pleasant flavor. Leaf removal must be moderate as the berries are a little sensitive to browning. Under certain conditions, after harvest, the stalks shrivel quickly and the berries have a tendency to fall off. The grapes have a moderate storage and transport capacity.
