Abstract:	Fifteen field fungi belonging to 10 genera and 5 storage fungi of the genera Aspergillus, Penicillium and Rhizopus, were isolated from 26 seed samples of 9 cultivars of soyabean. The field fungi causing reduction of seed germination or seedling emergence were Alternaria alternata, Cercospora kikuchii, Colletotrichum truncatum and C. dematium. Fusarium equiseti, F. moniliforme [Gibberella fujikuroi], F. pallidoroseum, F. oxysporum, F. solani and Macrophomina phaseolina caused root disease and damping off. A. alternata, C. dematium, C. truncatum, C. kikuchii, Curvularia lunata [Cochliobolus lunatus], Phomopsis sojae, Myrothecium verrucaria and Stemphylium botryosum [Pleospora tarda] caused foliage and pod disease. All seed samples of cultivars NARC-III, Crawford, William-82 and Century were infected, whereas some cultivars had no infection. The percentage fungal infection in individual samples varied from 0 to 14. High incidence of storage fungi (Aspergillus, Penicillium and Rhizopus spp.) reduced seed germination potential in vitro.
