A Mission to Explore the Genetic Resources
of Native North American Grape Species

Wild grapes (Vitis species) are able to thrive in harsh environments and under high disease and pest pressure conditions. Modern viticulture would not be possible without the exploitation of wild grape species native to North American. These grapes are mainly used as rootstocks and breeding germplasm to combat pests, pathogens and environmental stresses. A few of them are also used to make premium regional wines. They are natural sources for genes that confer tolerance to adverse biotic and environmental conditions. We have selected Vitis aestivalis 'Norton' for this program.
