Abstract

Sclerotium rot caused by Sclerotium rolfsii occurred on Cyclamen europaeum grown at the experimental greenhouse of Gyeongsangnam-do Agricultural Research and Extension Services in April 2013. Infected plants showed water-soaked appearance, wilting, and rotting; severely infected plants eventually died. White mycelial mats spread over lesions, and sclerotia were formed on leaves, petioles, and flower stalks near soil line. On the basis of mycological characteristics, ITS rDNA sequence analysis, and pathogenicity to host plants, this fungus was identified as S. rolfsii Saccardo. This is the first report of sclerotium rot on C. europaeum caused by S. rolfsii in Korea.

Key Words: Cyclamen europaeum, Sclerotium rolfsii, Sclerotium rot
