Abstract:The objective of this study is to explore the pathogen of stria-like lesions epidemically appeared in the pods of soybean variety "Tai 75" in China. Based on the pathogen isolated, morphological observation, rDNA ITS sequence analyses and pathogenicity tests, it is demonstrated that the lesion is a type of infection symptoms caused by fungal pathogen Colletotrichum truncatum (Schwein.) Andrus & W. D. Moore. The same pathogen infects soybean pods resulting in two main types of symptom on various soybean varieties. The stria-like lesions appeared exclusively in the soybean variety "Tai 75" whereas the round-blotches were observed with the other 6 soybean varieties tested. Pod disease incidence of stria-like lesions in the soybean variety "Tai 75" was 65.37%, whereas in the other 6 soybean varieties tested was 1.02%, 1.87%, 2.95%, 3.56%, 9.32%, 12.25%, respectively. The results showed clear host- and variety-dependent characteristics of infection of fungus C.truncatum.
