Other claims from this paper (5)
- Observation After inoculation with Venturia inaequalis, susceptible Malus cultivars showed extensive lesion development and hyphal elongation.
- Observation No typical scab symptoms were observed in the Pyrus species after inoculation.
- Observation In Pyrus, pathogen hyphal growth was inhibited after initial conidial germination.
- Observation The authors conclude that nonhost resistance to V. inaequalis is present in Pyrus species, both European and Asian pears.
- Recommendation The authors suggest that Pyrus could serve as a genetic source of novel, durable resistance for scab-resistant apple breeding.
