Abstract
Melampsora coleosporioides, which first appeared in New Zealand in 1978 on Salix babylonica, is believed to have been introduced from Australia by wind-borne spores. It overwinters in New Zealand in the uredial stage. Of 87 willow clones tested, only S. babylonica and some of its hybrids proved highly susceptible. Most other spp. showed satisfactory field resistance.
