Rangpur Lime x Troyer Citrange Trifoliate Hybrid Budwood

x Citroncirus spp.

This accession is Phytophthora resistant to a degree. In the nursery it produces vigorous, unbranched seedlings which are easy to bud. Seedling tests indicate that it is more susceptible to Phytophthora parasitica than Carrizo, but survival of field trees has been excellent. It is resistant to tristeza but susceptible to exocortis. It has grown well on a wide range of soils in Florida. Trees grown on this accession have a moderate growth rate resulting in trees 50 - 75 % of the height of those on Carrizo. Yield relative to tree size is good to excellent in most trials, as is fruit quality. Trees on this cultivar also showed moderate cold tolerance under Florida conditions. Overall it appears to be a rootstock worth of trial in higher density plantings. On the other hand it has not known advantages over C-35 citrange and somewhat poorer disease resistance.

Rootstocks of accession:  Carrizo citrange.

Season of ripeness at Riverside, California:  October to November.
