41-B DE MILLARDET
Chasselas x Berlandieri.
Rootstock largely used in limestone soils due to its high resistance: 40% to active limestone and up to 80% to total limestone.
Medium resistance to drought and low resistance to an excess of dampness.
Small and fleshy root system. Therefore, it has a slow development, but once the plant is well set it induces a good development and high fruit set, sometimes even excessive.
