SURVEY OF SEED-BORNE FUNGI OF SESAME (Sesamum indicum L.) SEED IN THE SUDAN

Abstract

This study was conducted to survey the seed–borne fungi of sesame collected from Elmuglad, Gedarif, Um Rawaba and Elrahad. Using the dry seed inspection, standard Blotter Method and Agar plate method. The dry seed inspection method revealed some impurities and discolored and damaged seeds. In the Blotter Method 11 seed-bone fungi were isolated from non-disinfected seed samples and 8 seed – borne fungi were isolated from disinfected seed samples. Also in the Agar plate Method 7 seed–borne fungi were encountered in sesame seeds. The two incubation method (Blotter and Agar plate) showed that the seed–borne fungi were encountered in higher percentage in the Blotter Method than in Agar Method. All the seed-borne fungi isolated sesame seeds in this investigation were identified as follows: Macrophomina phaseolina, Aspergillus niger, A. flavus, Alternaria sesami, Fusarium sp, Curvularia lunata, Alternaria alternate, Rhizobus sp., Ulocladium sp., Curvularia sp., Drechslera rostrata.
