Florida Citrus Rootstock Selection Guide, 4th Edition

This updated 4th edition of the Florida Citrus Rootstock Selection Guide (FLCRSG) is a revision of the 2016 publication. The guide is a convenient, easy-to-use reference to 21 characteristics of 49 rootstocks. Of those, 12 are time-honored commercial rootstocks (highlighted in blue), which are the most reliably characterized. The next 13 rootstocks are minor commercial ones (highlighted in green) that are less frequently used today in Florida but may have been prominent at one time. The third group consists of the most recently released 24 rootstocks (highlighted in yellow) for which there is limited commercial experience. The new addition includes three new USDA rootstocks and updates information on a few traits. Written by William S. Castle, Kim D. Bowman, Jude W. Grosser, Rhuanito Soranz Ferrarezi, Stephen H.
