Over 10% ofseeds harvested in 1991 and 1992 (50 samples, 400 seeds in each sample) proved to be infested with various fungi. <em>Fusarium</em> spp. and <em>Botrytis cinerea</em> were the most common pathogens isolated. <em>Fusarium avenaceum</em> was the most common and highIy pathogenic species. <em>Fusarium semitectum</em> and <em>F. tricinctum</em> were highly pathogenic to lupin seedlings but they were the least common <em>Fusarium</em> isolated from seeds. Similarily, <em>Sclerotinia sclerotiorum</em> was isolated only from 0,2% seeds tested but this fungus was highly pathogenic to lupin seedlings. Some other fungi know as lupin pathogens (<em>F. oxysporum, Stemphylium botryosum, Pleiochaeta setosa</em> and <em>Phomopsis leptostromiformis</em>) were also noted in tested seeds.
