Title
Occurrence of Stem Canker on Rape Caused by Leptosphaeria biglobosa in Korea
Abstract
Stem canker symptoms were observed in a rape field
in Muan, Korea during a disease survey in May 2006.
A total of 15 isolates of Phoma sp. were obtained from
the infected stems of the plant. All isolates were
identified as Leptosphaeria biglobosa based on their
morphological and cultural characteristics. The Korean
isolates of L. biglobosa were assigned to ¡®brassicae¡¯
among six subclades of L. biglobosa complex based on
the entire ITS sequences of rDNA. Pathogenicity of the
fungal isolates was confirmed on leaves and stems of
rape by artificial inoculation. This is the first report
that Leptosphaeria biglobosa causes stem canker of
rape in Korea.
