140 Ruggeri is a V. berlandieri x V. rupestris hybrid used as a rootstock. It was produced in 1894 in Sicily by Antonino Ruggeri. Dr Richard Smart (2015, p628) says this vigorous rootstock is well suited to dry [low fertility] soils high in lime, and Mediterranean climates but should not be planted on fertile, moist soils because of possible excess vigour. (140 Ruggeri’s competitive streak is useful however when replacing missing vines in an already established vineyard).
