Narrative
This is an isolate of the citrus concave gum graft-transmissible agent received from the Citrus Clonal Protection Program. According to Chet Roistacher, this is "a mixture of [tristeza, viroids, psorosis] and concave gum. Should be reindexed. Collected [1983] from 14A-20-2. In Exp 1456-14, inoc to MV as a source plant - has Ps, Tr, and [viroids]. [Viroid] status: positive." Note added 2002: apparent actual location of source 14D-21-02 based upon symptoms and metal tag on tree stating location is 14-20-2. This might be due to a renumbering of the always confusing Field 14. If you want, take a look at images of the source tree, the concavities, and the tag. (RR Krueger, 07/23/2012)
