Use(s): RootstockDog Ridge was selected in Texas from populations of V. champinii by T.V. Munson, the "Father of American Viticulture". This species is a natural hybrid between V. candicans and V. rupestris. Dog Ridge induces very high vigor in scions grafted on it, particularly on deep, fertile soils. This rootstock has strong resistance to root-knot nematodes, and has moderate phylloxera resistance. Dog Ridge is difficult to propagate and graft, and is best suited for infertile coarse-textured soils. It is rarely used now because of its very high vigor and the dense canopies it induces. Dog Ridge has relatively lobed leaves, with small rounded teeth, and reddened tendrils. It is a female vine and needs an external pollen source to set seed. An open pollinated seedling selected from a Dog Ridge cluster was used as the male parent in Freedom and Harmony.
