Abstract
|
|
|
|
A species of Corynespora was isolated from red-brown spots developed on leaves of soybean. The fungus was identified as Corynespora cassiicola and proved to be pathogenic to soybean plants. Growth of this fungus in vitro was optimal at 27℃, and poor at lower than 19 and higher than 35℃. Sporulation was abundant on the potato dextrose malt agar and moderate on V-8 juice agar and potato dextrose agar, The relative susceptibility of several soybean cultivars to Corynespora cassiicola was evaluated in the greenhouse. Cultivar Hwangkum of soybeans appered to be resistant to C. cassiicola and other cuitivars were susceptible or moderately resistant.
