Berlandieri Resseguier núm. 2 x Rupestris de Lot.
It is a hybrid obtained in Sicily.
Its resistance to limestone is similar to that of the Richter 110 and 99, but it is more resistant to drought and especially salt. It is considered the most resistant rootstock in both these aspects.
It is also very vigorous; therefore, it is suitable in plantations where vines have been grown before.
