Abstract

To extend the range of plants that can be grown on saline land and give a direct financial return, hybrids were produced between Eucalyptus camaldulensis lines selected for salt tolerance, and E. globulus selected for high pulp quality. There was a wide range of compatibility between the parents in terms of numbers of seeds per capsule, percentage germination and abnormal plants. Morphological traits inherited from the male E. globulus parent made it easy to confirm the hybrid status of the seedlings. Variability in leaf morphology made it impossible to distinguish the hybrids from the parents on the basis of leaf shape and size in the field, but the flowers and fruits of the hybrids were intermediate between the parents in shape and size. Hybrids were reproductively fertile and backcrossing with E. globulus was possible.
