Abstract
Puccinia psidii causes rust on neotropical Myrtaceae and exotic Eucalyptus spp.. Serious losses have been detected in Brazilian plantations of Eucalyptus. In the present work 27 provenances of 12 Eucalyptus species were screened for resistance to P. psidii present in the southern part of the State of Bahia, Brazil. Provenances of Eucalyptus pellita, E. urophylla E tereticornis, E. resinifera E camaldulensis, E. citriodora, E. microcorys and E. paniculata showed resistance to the population of P. psidii from South Bahia. Highly susceptible materials were detected among provenances of E. grandis and E. cloeziana. These results differed from previous observations in the neighbouring State of Minas Gerais. This suggests differences in pathogenic behaviour of the populations of P. psidii from those two areas.Keywords
