Abstract

Gray mold neck rot was observed on onion bulbs (Allium cepa L.) in low-temperature warehouses in Changnyeong-gun, Korea. The causative pathogen was isolated from rotted onion bulb lesions and identified as Botrytis aclada based on morphological and culture characteristics, the sequences of three nuclear genes (G8PDH, HSP60, and RPBZ), and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for Botrytis spp. identification. Although onion gray mold disease caused by B. allii, B. cinerea, and B. squamosa species has previously been reported in Korea, this, to the best of our knowledge, is the first report of B. aclada causing gray mold neck rot disease of onion bulbs in Korea.
