ABSTRACT
We studied genetic variation in Puccinia psidii, a newly introduced rust fungus in Hawaii, using microsatellite markers. All 36 Hawaiian P. psidii isolates analyzed had the same genotype at 11 microsatellite loci, while three genotypes were identified among four isolates from Florida and 11 genotypes among 18 isolates from Brazil. One of the isolates from Florida had 95% similarity to the Hawaiian isolates. We conclude that the genetically homogeneous P. psidii isolates in Hawaii might have derived from the same strain originally introduced into the Islands and are closely related to one of the strains found in Florida.
