Description Sorghum germplasm accessions (10) and breeding lines (3) exhibiting contrasting reactions to the grain mould complex (including Fusarium moniliforme [Gibberella fujikuroi], Curvularia lunata [Cochliobolus lunatus] and Phoma sorghina) were grown at Patancheru, India. Grains were harvested at different days after flowering (DAF) and analysed for ergosterol. Methanol and acidified methanol extracts of grains were analysed for flavan-4-ols. Ergosterol concn increased with increasing DAF in the mould-susceptible accessions and was 10-fold higher in grains collected at 50 DAF than in the corresponding mould-resistant accessions. It is suggested that ergosterol concn could be used to assess the magnitude of mould damage in sorghum grains. The correlation coeff. between ergosterol and flavan-4-ols concn was significant (P
