Abstract

Alternaria brassicae , Aspergillus flavus, Aspergillus niger and Peni‌cillium sp. were isolated from seeds of rape cv. Semu RT as seed - trans‌mitted fungi. Aspergillus flavus decreased the seed oil content to 37.04 % as compared with 46.68 for healthy seeds indicating about 21 % loss. The remaining fungi, however, showed moderate effect in this respect. Free fatty acids of seeds varied to different extents according to fungal invasion, where some increased in content , other decreased and some were only found in infected seeds, e.g. margaric, lauric, tridecylic and myrestic acids
