Abstract

Apple cultivars and selections were tested for resistance to two strains of Erwinia amylovora following shoot tip inoculation in the greenhouse. Cv. Liberty was resistant to strain Ea 273, and Priscilla, Delicious and Coop 17 were highly resistant to strain Apple # 1. A significant genotype x strain interaction was obtained suggesting a differential host × pathogen interaction. Segregation of seedlings derived from 16 controlled crosses after fire blight inoculation indicated that resistance to fire blight is quantitatively controlled with evidence for presence of dominant additive gene effects.
