Species: Interspecific Cross (berlandieri;rupestris)
Country of origin: Italy
Pedigree: V. berlandieri X V. rupestris
Berry color: None
Ruggeri selected 140Ru for the droughty limestone soils of Sicily. Italians consider it to be one of the most drought tolerant rootstocks, but it is too high in vigor for deep soils with moderate to high fertility. This rootstock is best suited to dry-farmed areas with shallow soils. 140Ru has good phylloxera resistance, is reported to have moderate resistance to root-knot nematodes (although this has not been tested in California), and good tolerance to lime-based soils. The leaves of 140Ru have a tendency to be more three-lobed than 110R and the leaf tissue puckers near the mid-vein. Otherwise it is very similar.
Foundation Plant Services at UC Davis is the source of Foundation grapevine material for the nursery industry, and the staff can provide information about possible sources for obtaining this stock.
The National Grape Registry (NGR) contains information about varieties of wine, juice, and table grapes, raisins, and grape rootstocks available in the United States. Growers, nurseries, winemakers and researchers can find background information and source contacts for those grape varieties in this single convenient location.
