    Citrus Research and Development Foundation

    In 2009, the Citrus Research and Development Foundation, Inc. (CRDF) was formed to coordinate citrus research funding in the face of huanglongbing (HLB, also known as “citrus greening”). While it addresses the full array of citrus research needs, CRDF has focused on HLB because it represents an existential threat to the Florida citrus industry.

  • Call for Grower Cooperators for Stage 1 Scion Trials to evaluate new citrus scions that may have elevated tolerance to HLB.

  • Call for Grower Cooperators for Scion Stage 1 Field Trials

    The Citrus Research and Development Foundation (CRDF) is establishing new field trials to evaluate new citrus scions that may have elevated tolerance to HLB. The trials are to be planted in late 2023 or the spring of 2024. The goal of the trials will be to identify plant material with the traits needed by growers to realize the highest possible pounds solids per acre and increased tree viability in the HLB era. The CRDF scion trial will be a Stage 1 field trial assessing new genotypes, most of which have not been fully evaluated and do not have sufficient “resumes” to be completely confident of success, which is why caretaking compensation to grower-cooperators is prescribed. Nevertheless, they have been selected by growers and scientists for these trials because of their potential. LEARN MORE »
