Description: UF/IFAS has approved the release of several new citrus rootstocks under its Citrus Fast Track Release Option. These citrus rootstocks were selected and released on the basis of their positive reaction to Huanglongbing disease (HLB, or citrus greening disease) in multiple experimental field trials under severe HLB disease pressure. Scion trees grafted onto these rootstocks showed a reduced frequency of infection and reduced disease symptoms once infected, when compared to other commercial diploid rootstocks. Long-term performance of trees on these rootstock selections is unknown, and yield and fruit quality data is limited. Furthermore, it is important to note that trees on these new rootstocks still require thorough psyllid control, and have performed best under experimental production systems that feature constant nutrition.
