Six species of Eucalyptus viz. E. alba, E. camaldulensis, E. microtheca, E. tereticomis, E. polycarpa and E. torelliana were subjected to a complete diallel mating. The cross between E. polycarpa and E. torelliana was characterised by post-fertilisation abortion. An evaluation of the remaining four parents and their 12hybrids for heterosis among parents revealed E. alba and E. tereticomis to record higher than mean performance. Among the hybrids, those of E. alba x E. tereticomis registered highest heterosis for most characters.
