The major positive attributes of this new rootstock are resistance or tolerance to citrus tristeza virus, Phytophthora palmivora, and Diaprepes root weevil, dwarfing effect on scion tree size, induction of high fruit quality, induction of good productivity per canopy volume on grafted scions, and ease of seed propagation. A notable negative of this rootstock may be a relatively high rate of tree loss after ten years of age to citrus blight or a similar disease. US-897 produces apomictic seed by nucellar polyembryony and is thus very easy to propagate uniformly by seed. Nursery studies have indicated that US-897 produces vigorous and true to type seedlings at a frequency similar to or better than that of most other commercial rootstocks.
