Suitability for cultivation and agronomic production

Centennial seedless is very vigorous and has a semi-erect to horizontally bearing. It must be trellised and pruned long.
Susceptibility to diseases and pests

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.
