Plant Improvement Rootstock Field Data
Welcome to the University of Florida’s IFAS Plant Improvement Team presentation of rootstock field trial data. The website’s objectives are to:
- Aid growers make timely and sound rootstock decisions;
- Ensure that the most promising new rootstocks are promptly moved forward in evaluation; and
- Enlist grower support in identifying promising rootstocks.
The Plant Improvement field effort involves about 60 trials that are mostly conducted in cooperation with citrus growers, on their property and under their management, in locations throughout the State of Florida. The trials vary in age and design but overall are intended to focus on certain horticultural traits [tree size, yield and juice and fruit quality] and tolerance to greening disease or Huanglongbing [HLB]. Data are collected and the website is updated annually. Trials are continuously posted to the website throughout the year.
Along with the rootstock data provided herein, the 4th edition  of the Florida Citrus Rootstock Selection Guide provides an updated online description of standard commercial and recently released rootstocks. It is a convenient, easy-to-use reference to 21 horticultural traits of 49 rootstocks. A special feature is an expert system based in artificial intelligence that emulates a human expert. It systematically sorts information available in the database and provided by users, then determines customized rootstock recommendations. The Guide provides rootstock selection assistance that complements the rootstock data presented herein. Improvements are highly desired. Please click on Site Feedback and provide your suggestions.
