Welcome to the California Citrus Improvement Program
The Citrus Research Program -- officially, the California Citrus Improvement Program -- is the grower-funded and grower-directed program established in 1968 under the California Marketing Act as the mechanism enabling the state’s citrus producers to sponsor and support needed research. The program is administered by the Citrus Research Board, which is better known in the industry as simply “CRB.”

There are three components to the Program:

  • General research
  • Quality assurance (CCQC)
  • Variety improvement and registration (Citrus Clonal Protection Program)


  • Concerning this website...
    Technical difficulties since late June have required that this site be taken offline periodically, and updates could not be posted.  Certain sections are now undergoing reconstruction and are not fully functional, and we apologize.  Please note that CRB meeting information is also posted on the CDFA Marketing Branch website at www.cdfa.ca.gov

    Basics of Good Agricultural Practices for Citrus Growers
    Food safety begins in the grove.  This information is designed to encourage growers of fresh citrus to learn more about what it takes to have a food safety management plan for their operations.  In this introductory overview, producers will find the basics needed to plan, execute and document cultural practices that will lessen possibilities of fruit contamination.  Growers are strongly encouraged to delve deeper into this important subject.  CRB will be assisting in this process with periodic updates and advanced guidance documents in the coming months.

    California Citrus Quality Council

    The quality assurance portion of the California Citrus Improvement Program is conducted by the California Citrus Quality Council (CCQC) under an operating agreement with the Citrus Research Board. CCQC furnishes California citrus growers and their shippers with technical information and procedural guidance to assure the marketing of citrus fruit that complies with the chemical residue, food safety, phytosanitary and labeling requirements of the U.S. and all importing countries.

    Citrus Clonal Protection Program (CCPP)
    The Citrus Clonal Protection Program operates specifically for the purpose of eliminating the spread of bud-transmitted pathogens in citrus by providing variety improvement through importation, indexing and certification of budlines, by the direct elimination of pathogens from infected budlines, and by the maintenance, evaluation and registration of budwood source trees. The CCPP program is maintained jointly by the Citrus Research Board and the University of California in cooperation with the California Department of Food and Agriculture and USDA.
