Abstract

‘UFR-4’ is a new and distinct allotetraploid citrus rootstock for tree size control and improved disease resistance. ‘UFR-4’ has shown a positive reaction to the Huanglongbing disease (HLB, or citrus greening disease) in multiple experimental field trials. Scion trees grafted on this rootstock show a reduced frequency of infection and reduced disease symptoms once infected when compared to commercial diploid rootstocks. ‘UFR-4’ rootstock also showed tolerance to the Diaprepes/Phytophthora complex in greenhouse tests.
