The Chip Bud Method is performed shortly after the grape vine is planted, giving the rootstock enough time to become active but the bud of the grape vine is still inactive. It is performed by cutting two small slopes in both sides of the rootstock and cutting a small scion into a small bud and placing the scion bud into the cuts made on the ...
One of the newest rootstocks of the "CG" series, only released commercially in 2004, is CG5202(G.202) which adds resistance to the woolly apple aphid, and when combined with highly resistant cultivars such as "Liberty" it is showing great potential. [4] [5] Rootstocks based on Siberian Crab apple are being used in colder areas for more cold ...
The development and registration of new clones take place by means of local clone selection in old plantations, as well as the importation of high quality clones from abroad, for local evaluation. A clone is the vegetative offspring of one specific mother plant; it does not show any genetic, morphologic or physiologic deviations from the mother ...
Grafting is often not a complete cloning method because seedlings are used as rootstocks. In that case, only the top of the plant is clonal. In some crops, particularly apples, the rootstocks are vegetatively propagated so the entire graft can be clonal if the scion and rootstock are both clones.
AxR1 is a grape rootstock once widely used in California viticulture.Its name is an abbreviation for "Aramon Rupestris Ganzin No. 1", which in turn is based on its parentage: a cross (made by a French grape hybridizer named Ganzin) between Aramon, a Vitis vinifera cultivar, and Rupestris, an American grape species, Vitis rupestris—also used on its own as rootstock, "Rupestris St. George" or ...

As a climbing or trailing vine , it is widely distributed across central and eastern Canada and the central and northeastern parts of the United States , from Quebec to Texas , and eastern Montana to Nova Scotia .
The overwhelming majority of Blanc du Bois is grown on its own rootstock, although the vine does not perform well in calcareous soils, such as those found in much of Texas. In these cases, some vineyards graft the Blanc du Bois vine onto rootstock that is resistant to Pierce’s Disease and also tolerant of a soil pH greater than 7.0. [1]
