Eucalyptus globulus and Eucalyptus nitens were evaluated for resistance to rust caused by Puccinia psidii. Seedlings were inoculated with a single urediniosporic pustule isolate of P. psidii (UFV-2) obtained from E. grandis from Itapetininga, SP. Disease assessment was carried out 12 days after inoculation based on a rust rating scale with four class of severity (S0, S1, S2 and S3). Percentages of resistant plants were 60% and 50% for E. globulus and E. nitens, respectively. The high intra-specific variability found in this study allows using the clonal propagation of resistant genotypes in commercial plantations or in breeding programs.
