Fifteen field fungi belonging to 10 genera and five storage fungi of the genera Aspergillus, Penicillium and Rhizopus were isolated from twenty six seed samples of nine cultivars of soybean. The field fungi causing reduction in seed germination or seedling emergence were Alternaria alternata, Cercospora kikuchii, Colletotrichum truncatum and C. dematium. The fungi causing diseases of roots and damping-off comprised of Fusarium equiseti, F. moniliforme, F. pallidoroseum, F. oxysporum, F. solani and Macrophomina phaseolina while pathogens causing foliage and pod disease were A. alternata, C. dematium, C. truncatum, C. kikuchii, Curvularia lunata, Phomopsis sojae, Myrothecium verrucaria and Stemphylium botryosum. All seed samples of four cultivars namely NARC-III, Crawford, William-82 and Century were found infected to some degree whereas 50 to 66.70 percent samples of other five cultivars showed no infection. Range of fungal infection percentage in individual samples varied from 0.00 to 14.0. High incidence of storage fungi (Aspergillus, Penicillium and Rhizopus spp.) reduced seed germination potential in-vitro.
