Fire blight resistance of 8 wild pear seedlings ( Pyrus communisL.) found growing in South-western Ontario was measured and 5 were found to be significantly more resistant than Bartlett, 2 were significantly as resistant as Kieffer and 1 was significantly as resistant as Old Home. The most resistant seedling, called Iler, was over hundred years old and has a stem circumference of 5.4 m and a height of 17.1 m. It is probably derived from the Mission or Jesuit pears that were brought to this region by the French settlers in the eighteenth century. The fruit of all seedlings is inferior in quality to that of commercially grown cultivars.
