ABSTRACT: Twenty-five species of fungi were isolated from the seeds of twenty rice varieties (BRRI dhan 56 to BRRI dhan 75) collected from Bangladesh Rice Research Institute (BRRI). The fungi were isolated from the samples following “Tissue Planting” method and “Blotter” methods. Among the isolated fungi, Bipolaris oryzae, Curvularia lunata, Fusarium equiseti, F. fujikurori, Microdochium fisheri and Nigrospora oryzae showed pathogenic potentiality following seed inoculation technique. These pathogenic fungi had remarkable effect on seed germination, root shoot length and mortality of rice seedlings. The present report is the first record of Microdochium fisheri as a pathogenic fungus for Bangladesh.
