The accumulation of fumonisin B1 (FB1) and fumonisin B2 (FB2) after inoculation of 14 maize hybrids with Fusarium moniliforme has been examined in Poland during the seasons 1992–1995. Fumonisins have been detected in all 14 hybrids in amounts ranging from 0·09 mg kg-1 FB1+0·02 mg kg-1 FB2 to 93·2 mg kg-1 FB1+15·8 mg kg-1 FB2. Inoculated ears contained from <1% up to 60% of Fusarium damaged (=mouldy) kernels (FDK). Fumonisins' levels in FDK ranged from 5·1 mg kg-1 FB1+1·4 mg kg-1 FB2 up to 196·0 mg kg-1 FB1+62·0 mg kg-1 FB2. Significant influence of the year of inoculation on ear infection and fumonisins accumulation was observed. Only one hybrid (Mona) exhibited low disease score, low percentage of FDK (1·1–2·6%) and low levels of fumonisins (FB1 from 0·09 to 1·66 mg kg-1 and FB2 from 0·02 to 0·42 mg kg-1) during 3 years of experiments.
