Released rootstock from the USHRL program that has been extensively evaluated in Florida by USHRL personnel as indicated in the source history. More information on these evaluations is available from Dr Kim Bowman of USHRL. It has also been included in some trials in California conducted by Prof Mikeal Roose of the University of California, Riverside. According to the Release Notice, "In all field avaluations, US-802 rootstock yielded vigorous and productive trees that were tolerant to endemic disease and pest problems and exhibited excellent survival. The major positive attributes of this new rootstock are resistance or tolerance to citrus tristeza virus, citrus blight, Phytophthora palmivora, and Diaprepes root weevil, induction of high vigor and good fruit productivity on grafted scions, and ease of seed propagation. Notable negatives may be the tendency for trees grafted on US-802 rootstock to become very large and produce fruit with intermediate or low soluble solids concentration.
