Expert System for the Florida Citrus Rootstock Selection Guide, 4th Edition


Florida Citrus Rootstock Selection Guide. I don't replace the guide, but rather am intended to be used alongside it. I will interview you and can reason through your information to hone in on your best rootstock options. Over time, I'll keep learning in a way that will make my answers even better. Here are the ways I can help you:

  • Provide a measure of confidence that a rootstock is suitable
  • Easily test different rootstock planting scenarios
  • Serve as a "second opinion" if you already selected your rootstock
  • Provide rootstock suggestions you may have overlooked
  • Help you get started with a new selection that considers the latest rootstocks

My analysis will provide a report that gives you a ranked list of rootstocks that ON AVERAGE are top candidates for you to consider in your situation. Please be sure to read the disclaimer below before proceeding.

What rootstock traits do you want to consider today for the location? You may wish to read over our introduction to rootstock selection on our website as you think about making the best choice. You may select more than one group of traits. I will ask for a little more information about each group you choose.

Planted Variety (*This question is required):

What type of variety do you want to plant on this rootstock? I will use this information to help you avoid certain issues with rootstock-scion incompatibility. Learn more...

                    
Horticultural Traits (Select 3 to 5 traits to help us determine the best match for your situation):

Leave any questions below unanswered if they are not important priority decision factors. Selecting fewer than 3 and more than 5 options makes it harder for us to find an appropriate match.


Tree Size: What size canopy relative to other trees? Select up to two sizes. Learn more...

           
Tree Spacing: Feet between trees within the same row. Select up to three spacings. Learn more...

                          
Yield per Tree: Relative yield per tree? Select up to two. Learn more...

                 
Yield per Acre: Relative yield per acre in 90-pound boxes? Select up to two. Learn more...

How to Use These Results

The information below is just one of several sources that must be consulted to make an informed rootstock selection. Other sources include the Florida Rootstock Selection Guide, other growers, our reference bibliography and your own experience. Based on your answers to the questions in this interview, here are my suggestions for rootstocks that come closest to meeting your needs.

The term, Selection Score, shown in the rankings immediately below the rootstock name is not a statistical value. Instead, it refers to a relative ranking of my confidence that rootstock is suitable on average for the conditions you described. The closer in value the Selection Score for a rootstock is to 100.00, the closer the match of that rootstock is for your situation.

IMPORTANT NOTE: Selecting Recently Released rootstocks involves more risk because of less time and scope of evaluation.

You selected a total of 0.00 traits in this session. Here are the selections you made for how to perform this analysis: - Evaluate horticultural traits - Evaluate site tolerances - Evaluate pest and disease traits - Evaluate rootstocks from all release dates - Show all rootstocks, including positively- and negatively-rated ones. Negatively-rated rootstocks are rootstocks that did not meet your minimum criteria

Compare these results to the rootstock selection table at flcrsg.com. The colors highlighted in the release category correspond to the same colors in the online rootstock table.


Rootstock Rankings - ordered from top to bottom

The maximum Selection Score for any single rootstock is 100%.

If you don't see any rootstocks in a bullet list in the next section below, it means I'm not sufficiently confident in this instance to make recommendations. You might try clicking the Back button at the bottom right corner of this page to go to the prior screen, then lower the confidence level which I'll use to revised this report.
