초록

Blue mold is the most important postharvest disease of apples in Korea. Apple fruits with blue mold symptoms were collected from storages in different locations in Korea and were investigated for their association with Penicillium species. A total of sixty five isolates of Penicillium were sampled from the collected apples. Based on DNA sequence analysis of β-tublin gene and ITS and lsu rDNA (ID region) and morphological characteristics, they were identified as P. crustosum, P. expansum, P. italicum, P.
solitum and P. sp.. P. sp. which is closely related to P. hirsutum is a new species, not reported before. P. expansum (35%)was predominant species followed by P. crustosum. The phylogenetic tree inferred from combined β-tublin and ID region sequence showed good correlation with species that are defined by morphological characteristics. In pathogenicity test, apples were wound-inoculated with conidial suspension and incubated at 20-22℃. The most severe and destructive species was P.
expansum. The species caused a decayed area 42-50㎜ in diameter after 8-10days. Decayed area caused by P. crustosum and P. sp. was 26-32㎜ and 20-26㎜, respectively. This is the first record of P. crustosum, P. italicum and P. sp. from apple in Korea.
