(ABC10) - UC Davis Professor Andrew Walker spent more than a decade breeding a new variety of grapes that is resistant to Pierce's Disease. The grapes from the resistant plants are similar in flavor to your typical red and white wine variety. The only difference is that nameless plants are bred to resist Pierce's Disease. 

Walker's plants will not replace current varieties. They will be marketed to area that have a history of Pierce's Disease. Wine makers will be able to add or blend disease resistant grapes to non-resistant grapes. Walker hopes this plant will keep grape growers from going out of business should another outbreak of Pierce's Disease strike again. 

End the new grapes are expected to go to market next year. It could take 6 to 7 years before the Pierce's Disease resistant grapes are made into wine.
