World of CitrusFurr C-57 Citrandarin
Niles, Freckman, and Roose reported C-57 in a 1995 greenhouse comparison of citrus rootstocks for resistance to citrus nematode. In the reported pot and cone experiments, C-57 showed greater resistance than the Rubidoux comparison; the authors said further trials were needed.
Coauthored the reported evaluation of C-57 resistance to citrus nematode.

John Carpenter and Joe Furr produced selection C-57 by crossing Sunki Mandarin as the seed parent with Swingle Trifoliate as the pollen parent through the USDA citrus-rootstock breeding program at the United States Date and Citrus Station in Indio, California. The exact cross date is not established in the available release sources.
