Abstract
We developed a method of evaluating the resistance of strawberry to anthracnose disease (Glomerella cingulata) by testing the self-established seedlings of the cultivar. The survival rate of the seedlings decreased rapidly after spray inoculation with fungal spores, but there was no significant difference in survival rates from 20 to 34 days after inoculation. The survival rates 34 days after inoculation increased with increasing seedlng age at the time of inoculation, up to a maximum at 2 weeks after germination. We thus recommend using seedlings that had germinated more than 2 weeks before inoculation and then calculate survival 20 days after inoculation. There were strong correlations between disease indices calculated using vegetatively propagated plants and the survival rates after inoculation of self-established seedlings. This study showed that evaluation using self-established seedlings is effective.
