Abstract
Five selections of Malus spp., from USA, used as race differentials for the apple black spot fungus Venturia inaequalis, were inoculated with nine Australian isolates of the fungus—six from Queensland, two from Victoria, and one from South Australia. The reactions of the five Malus selections indicated that all nine isolates of V. inaequalis were race 1.
