Abstract: The utility of chloroplast (cp) DNA in Eucalyptus, either as a molecular marker for genetic studies or as a potential vehicle for genetic manipulation, is based on knowledge of its mode of inheritance. Chloroplast inheritance in angiosperms can vary among and within species, and anomalous inheritance has been reported in some interspecific hybrid combinations. In Eucalyptus, abnormalities of pollen tube growth occur in a number of interspecific hybrid combinations, and this could increase the likelihood of anomalous chloroplast transmission. We used a rapid PCR technique to determine cp heritability in 425 progeny of Eucalyptus, comprising 194 progeny of the premier pulpwood species, E. globulus, and 231 interspecific hybrids between E. globulus and E. nitens (F1, F2, and backcrosses). At this sampling intensity, no pollen-mediated transmission of cpDNA was found in any of the 40 families tested. The results are discussed with reference to cp engineering and the use of cpDNA as a seed-specific marker in phylogeographic studies of Eucalyptus
