Tahiti lime, Citrus latifolia Tanaka (Rutaceae), is susceptible to Citrus Tristeza Virus (CTV), and if affected, decreases the profitability of the crop. In the well-drained high terrace of the Meta piedmont, the influence of the virus attack was evaluated on the performance of Tahiti lime grafted on six rootstocks (Carrizo; Sunki × English; Sunki × Jacobson; Pomeroy; Rubidoux, y Kryder 15-3) on a completely randomized experiment design taking each tree as an experimental unit. A comparison of means and inferential statistic were used for: plant height, height and canopy diameter; canopy volume, yield and severity of CTV. All rootstocks showed homogenous height. Carrizo was the exception with less size and canopy volume. The highest accumulated fruit yield (Kg/tree) wasobtained by Sunki x English, followed by Rubidoux and the lowest yield was obtained by Carrizo. The highest yield efficiency of average canopy volume was obtained with Sunki x Jacobson. The Tahiti lime yield and morphological development fell in the seventh year (2007) in all rootstocks, due to an infection caused by a mix of isolates of CTV type Madeira and type B128, isolates which cause stem channeling : type B31 which causes moderate stem channeling and B7 and VT isolate,
