| Abstract:
An artificial inoculation test method was established in the laboratory to evaluate resistance of cherry genotypes to the leaf spot fungus, Blumeriella jaapii. The reaction type to leaf spot of 52 sour cherry cultivars/clones, 7 sweet cherry cultivars and 11 Prunus species was evaluated. In result, 10 sour cherry cultivars/clones showed a resistant reaction type to leaf spot. All sweet cherry cultivars tested were susceptible. The Prunus species, P. canescens, P. incisa, P. kurilensis, P. maackii, P. nipponica, P. sargentii, P. serrulata ssp. spontanea, P. subhirtella showed a resistant reaction type to the leaf spot fungus. The species P. dawyckensis was susceptible. | |
