Abstract

Fungi associated with sorghum (Sorghum vulgare) seeds collected from eight different locations viz. Jamalpur, Kushtia, Mymensingh, Pabna, Rajbari, Rajshahi, Savar and Sherpur of Bangladesh were detected by Blotter method. About 36% of the sorghum seeds were infected by different species of fungi obtained from the selected locations and nine different fungi identified in order of prevalence, were-Curvularia lunata, Fusarium moniliforme, Alternaria tenuis, Bipolaris sorghicola,Colletotrichum graminicola, Botrytis cinerea, Aspergillus niger, Penicilliumoxalicum and A. flavus. Of all these fungi, the most predominant fungus was C.lunata (17.4%). The other predominant fungi were F. moniliforme (16.2%), A.tenuis (15.7%), B. sorghicola (11.4%), C. graminicola (11.3%) and B. cinerea(10.0%). The fungi varied in prevalence with respect to location of seed collection. No definite relationship between germination and seed-borne fungal infection was observed.

Key words: Prevalence, seed-borne fungi, locations, sorghum.
