rootling, a one-year-old vine grown in a nursery, the common material used for planting a vineyard. Typically, it is a grafted rootling, with the fruiting variety, or scion, grafted on to a rootstock. Most species of the vine genus vitis, especially vinifera varieties, form roots readily on their cuttings, but some rootstocks such as Vitis berlandieri and Vitis champini form roots poorly.
