Citrus Rootstock Selection Guide

Florida Citrus Rootstock Selection Guide, 3rd Edition. William S. Castle, Kim D. Bowman, Jude W. Grosser, Stephen H. Futch and James H. Graham. The authors also wish to gratefully acknowledge the following colleagues who contributed significantly to the first two editions of this publication: Dr. Alfred H. Krezdorn [deceased], Dr. David P. H. Tucker and Mr. Charles O. Youtsey.

The last edition of this guide was published in 2006. Much has changed since then in the Florida citrus industry mostly because of the discovery and spread of the bacterial disease, Huanglongbing [HLB]. Rootstocks were not initially part of the discussion related to managing HLB, but that, too, has changed particularly given the accumulating evidence that trees on various rootstocks may differ in the incidence of the disease. Therefore, the authors have prepared this timely and necessary update of the former edition as well as considerably expanding the list of rootstocks to include many that have not yet undergone the usual extensive field evaluation in Florida. These new rootstocks offer improvements of many meaningful traits, such as tree size control, high yield and juice quality and possible HLB tolerance that appear essential to the future of our citrus industry.
